The Silverado 1500 has run through five distinct bodies since 1999, and the fitment breaks are sharper than most listings suggest. Two examples that cost people money: the crew cab short bed changed from 5'7" to 5'8" in 2019, and in that same 2019 model year Chevrolet sold two completely different trucks under the Silverado 1500 name at the same time.

The Five Generations at a Glance
| Generation | Years | Platform | What defines the break |
|---|---|---|---|
| Classic body | 1999–2006, plus 2007 "Classic" | GMT800 | Shares interior architecture with same-era Escalade, Suburban and Yukon XL |
| Second generation | 2007–2013 | GMT900 | New cab; bed dimensions largely carried over from the previous truck |
| Third generation | 2014–2018, plus 2019 "1500 LD" | K2XX | Crew cab short bed measures 5'7" |
| Fourth generation | 2019–2026 | T1XX | Crew cab short bed grows to 5'8"; interior fitment splits by seat and floor configuration |
| Silverado EV | 2024–2026 | Ultium (BT1) | Entirely separate accessory ecosystem; nothing from the gas trucks carries over |
The One-Inch Bed Change That Breaks Fitment
This is the clearest illustration of why generation matters, and it is one inch.
On the 2014–2018 truck, the crew cab short bed is 5'7". On the 2019–2026 truck, the crew cab short bed is 5'8". You can see it in how bed liners are catalogued — they are sold as separate products, one cut for 5'7" and one for 5'8", at the same price, and they are not interchangeable.
SmartCoverage Bed Liner — 2014–2018 Crew Cab, 5'7" Bed
From $132.29 — cut specifically for the 5'7" K2XX box. Will not fit the 2019 and later bed.
SmartCoverage Bed Liner — 2019–2026 Crew Cab, 5'8" Bed
From $132.29 — cut for the 5'8" T1XX box, and shared with the equivalent GMC Sierra 1500.
Same truck name, same cab style, same trim of product, one inch apart, two different part numbers. Anything that references the bed floor or the bed rails — liners, covers, tool boxes, rack systems — inherits this break.
2019: The Year Two Different Trucks Wore the Same Badge
If you own a 2019, this is the most important paragraph on the page.
When the new T1XX truck launched for 2019, Chevrolet kept building the previous-generation K2XX truck alongside it and sold it as the Silverado 1500 LD. Two trucks, same model year, same nameplate, completely different bodies.
You can see this reflected in how parts are catalogued. A set of crew cab running boards is listed as fitting 2007–2018 Silverado 1500 crew cab and 2019 1500 LD — grouping the 2019 LD with the older body it actually is, not with the model year it shares.
-
6" Stainless Running Boards — 2007–2018 Crew Cab + 2019 1500 LD
From $210.99. Stainless steel, 500 lb rated, two-piece. The fitment line is the point: 2019 appears here only as "1500 LD," alongside the 2500HD and 3500HD, because the LD is the old body.
Practical rule for 2019 owners: find out which truck you have before ordering anything. If the badge or the paperwork says LD, shop the 2014–2018 listings. If it does not, shop the 2019–2026 listings. Ordering off the model year alone is a coin flip.
Why 1500 and HD Year Ranges Don't Line Up
The common question is whether a 2500HD part fits a 1500. The honest answer is sometimes — but the year ranges do not match, which is where people go wrong.
| Product | 1500 coverage | HD coverage |
|---|---|---|
| Second-generation crew cab liners | 2007–2013 | 2007–2014 |
| Third-generation crew cab liners | 2014–2018 | 2015–2021 |
| Fourth-generation crew cab liners | 2019–2026 | 2020–2026 (2500/3500 with bench) |
The HD trucks changed body a year after the 1500 did, every single time. So a 2014 2500HD is still the old body while a 2014 1500 is already the new one. Two trucks in the same driveway, same year, same brand, and the interior parts do not swap.
When a listing does cover both, it says so explicitly and gives both ranges. When it gives only one range, take it literally.
Cab Style Matters as Much as Year
Within a single generation, crew cab, double cab and extended cab are three different floor plans, and anything that touches the floor is cut differently for each.
-
Smart Trim Floor Liners — 2007–2013 Crew Cab
From $92.99. Covers 1500 crew cab 2007–2013 and 2500/3500 HD crew cab 2007–2014 — the offset year range in a single listing. -
SMARTLINER Floor Liners — 2007–2013 Extended Cab
From $69.74. Same generation, same years, different cab — and a different part at a different price.
Two listings, one generation. The only variable is cab style, and it is enough to change the part.
On the Newest Trucks, Interior Fitment Splits Even Further
The 2019–2026 truck adds a layer that older generations did not have. Interior fitment now depends on how the cab was optioned, not just its shape. For the Double Cab alone, liners are catalogued separately by:
- First row bucket seats versus first row bench seat
- Second row under-seat storage present or absent
- Carpet flooring versus vinyl flooring
- Over-the-hump coverage or not
-
SMARTLINER — 2019–2026 Double Cab, Bucket Seats, Carpet, No Under-Seat Storage
From $92.99. Note how much qualification sits in that title. Every clause is a fitment condition. -
SMARTLINER — 2019–2026 Crew Cab, Bench Seat, No Under-Seat Storage
From $107.99. Covers 1500, 2500 and 3500 crew cabs together, but only with the bench seat configuration.
Before ordering interior parts for a 2019 or newer truck, go sit in it. Bucket or bench, carpet or vinyl, storage under the rear seat or not — those four answers determine which part you need.
Beds and Cabs Change on Different Schedules
Here is a nuance that works in your favour. The cab and the bed do not always change at the same time, so bed accessories sometimes span a cab generation break.
A roll-up tonneau cover is catalogued for 2004–2013 Silverado and Sierra 1500 — a range that crosses the 2007 cab change entirely. The cab was redesigned; the box it sits behind was close enough that one cover covers both. Conversely a hard tri-fold is listed for 2007–2014, and another for 2014–2019 at 6.5 feet — ranges that follow the bed, not the cab.
-
Roll-Up Tonneau Cover — 2004–2013 Silverado 1500
From $379.99. Spans the 2007 cab redesign, because the bed carried over. -
Hard Tri-Fold Tonneau — 2014–2019, 6.5 ft Bed
From $679.99. Measure your bed rather than assuming from trim — the 6.5 ft box is a different part from the short box. -
Soft Tri-Fold Tonneau — 2020–2021 2500HD / 3500HD
From $489.99. The HD-specific range again, starting a year after the 1500's.
The takeaway: measure the bed. Do not infer it from the model year or the trim badge.
1999–2007 Classic Body
Interior parts from this era are frequently shared with the same-period Escalade, Suburban and Yukon XL, because those vehicles share the underlying architecture. That widens your options on liners considerably.
-
SMARTLINER Floor Liners — 1999–2007 Crew Cab
From $78.99. Also fits 2000–2006 Escalade, Suburban and Yukon XL. The shared-architecture range works both directions when hunting for stock. -
SMARTLINER Floor Liners — 2001–2007 Double / Extended Cab
From $78.99. The listing says "Classic Body Style" explicitly, which is how the 2007 overlap year gets disambiguated. -
LED Tail Light — 2003–2006 Silverado
From $102.88. A narrower window than the full generation, which is typical for lighting — lamp housings changed mid-generation more often than sheet metal did.
2007 is the other overlap year to watch. The GMT800 "Classic" was sold alongside the new GMT900 truck, the same way 2019 would later play out. Listings that say Classic Body Style are telling you which one they mean.
2014–2018 (Plus 2019 LD)
This generation is where lighting upgrades get interesting, because GM changed headlight systems within the generation and retrofit harnesses exist to bridge them.
-
SmartCoverage Floor Liners — 2014–2018 Crew Cab
From $69.74. The HD range runs 2015–2021 on the same part, which is the offset in plain sight. -
LTZ Headlight Retrofit Harness — 14–15 (all) and 16–19 (2500/3500)
From $341.99. Exists because the 2016 facelift changed the headlights mid-generation. The harness is what makes the newer lamps work on the earlier truck.
2019–2026
-
6" Stainless Running Boards — 2019–2023 Crew Cab
From $198.99. 500 lb rated. HD coverage runs 2020–2024 on the same part — the offset once more. -
Wheel Well Storage Box — 2019–2021, Driver Side
From $159.99. 6.6 gallon, lockable, waterproof ABS. Sold as side-specific — the passenger side is a separate part, so check which side you are ordering. -
LED Headlight Harness — 19–22 Silverado 1500
From $399.99. For moving a halogen-equipped truck to the factory LED lamps. A separate DRL relocate harness exists for halogen models, so confirm which your truck left the factory with.
Silverado EV: A Separate Ecosystem
The Silverado EV shares its name with the gas trucks and almost nothing else. It is built on the Ultium platform with a different body, a different bed and a different rail system, so gas-truck accessories do not carry over regardless of how close the model years are.
Be realistic about where the aftermarket is. The EV is a new platform and its dedicated accessory catalogue is small — at present there are three genuinely Silverado EV-specific products, and everything else you might buy is general-purpose. That is not a criticism of the truck; it is simply where a young platform sits, and it will expand.
What does not carry over: bed liners, tonneau covers, bed rail accessories, tool boxes sized to a gas truck's rails, running boards, and console organisers. The EV bed, rails and console are all different.
What does carry over: genuinely universal items — phone mounts, USB chargers, dash cams, and cargo straps. Anything that mounts to the vehicle rather than sitting in it needs EV-specific fitment.
The three EV-specific parts
-
Silverado EV Electric Retractable Tonneau — 2024–2026
From $1,753.17. Aluminium alloy, power retractable, custom fit with no-drill installation. The standout dedicated option, and the one that most clearly demonstrates the point — no gas-truck cover fits this bed. Because it adds powered components, professional installation is a reasonable choice even though the mounting itself requires no drilling. -
Bed Rail Stake Pocket Covers — Silverado EV / Sierra EV
From $38.19. The cheapest useful thing on this list and worth doing early — open stake pockets collect water, road salt and debris. Note the listing covers the GMC Sierra EV too, since the two share the platform. -
Silverado EV Console Storage Tray — 2024–2026, 2 pcs
From $58.73. Double-layer ABS organiser moulded to the EV console. Gas-truck console trays do not fit, because the console geometry is different.
General-purpose additions that do apply
-
Truck Bed Tie-Down Anchor Clips
Useful for securing cargo under a closed tonneau. Check the clip style against your EV's rail profile before ordering, since the rails differ from the gas trucks. -
Magnetic Car Phone Holder
Genuinely universal. Useful on longer routes where you are running a charging-stop app alongside navigation. -
Dual-Lens 4K Dash Cam
Mounts to glass rather than to the vehicle structure, so platform differences do not affect fitment.
How to Identify Your Generation Before You Order
- Check the model year, then check for an overlap. 2007 and 2019 are both dual-body years. If you own either, the year alone does not identify your truck.
- Look for an LD or Classic badge on a 2019 or 2007 respectively. That is the tell.
- Measure the bed from the inside of the tailgate to the front bulkhead. Do not trust the trim name.
- Count the doors and check how the rear ones open. Crew, double and extended cabs take different interior parts.
- Sit inside and note the configuration — bucket or bench first row, carpet or vinyl floor, under-seat storage present or not. On 2019 and newer trucks these determine interior fitment.
- Read the full listing title. On well-catalogued parts every fitment condition is stated in the title, including the cab, the bed length, the seat type and both the 1500 and HD year ranges.
Prices shown here are starting prices at the time of writing and change with variant and availability. Always confirm fitment against your own VIN before ordering.
Frequently Asked Questions
How do I know if my 2019 Silverado is the old body or the new one?
Look for the LD designation. Chevrolet sold the previous-generation truck as the Silverado 1500 LD alongside the new 2019 truck. Parts listings group the 2019 LD with 2007–2018 trucks, not with 2019–2026 ones, which tells you which body it actually is.
Will a 2500HD accessory fit my 1500?
Sometimes, but never assume from the model year. The HD trucks change body roughly a year after the 1500, so a 2014 1500 and a 2014 2500HD are different generations. When a part covers both, the listing states both ranges explicitly — for example 1500 2014–2018 alongside HD 2015–2021.
Did the bed really only change one inch?
Yes, and it is enough. The crew cab short bed went from 5'7" to 5'8" between the 2014–2018 and 2019–2026 trucks, and bed liners are sold as separate, non-interchangeable products for each.
Why do some tonneau covers span two cab generations?
Because the cab and the bed do not always change together. A cover listed for 2004–2013 crosses the 2007 cab redesign, since the box behind the cab carried over. Bed accessories follow the bed's timeline, not the cab's.
Why does the floor liner listing ask about my seats?
On 2019 and newer trucks, interior fitment depends on first-row seat type, flooring material and whether the second row has under-seat storage. The same cab in the same year takes different liners depending on how it was optioned.
Will regular Silverado accessories fit the Silverado EV?
Assume not. The EV is a different platform with a different body, bed and rail system, so anything that mounts to the truck needs EV-specific fitment. Only genuinely universal items — phone mounts, chargers, glass-mounted dash cams — transfer across.
Are floor liners available for the Silverado EV yet?
Not as dedicated EV parts at present. The EV accessory catalogue currently runs to a tonneau cover, stake pocket covers and a console tray. This will expand as the platform matures, and gas-truck liners are not a workaround in the meantime.
Are older generations still well supported?
Reasonably. The classic-body trucks benefit from sharing architecture with same-era Escalade, Suburban and Yukon XL, which widens the parts pool. Selection narrows over time, but core protection and wear items remain available.
What's the single most common fitment mistake?
Ordering off the model year alone. Year gets you close; cab style, bed length, tonnage and — on newer trucks — interior configuration get you the right part.
