Fifty-eight series here fit the Sierra 2500 HD and 3500 HD. Each generation has a standard bed and an 8 ft long bed, but cover makers label them differently:
| Sierra HD years | Standard bed, listed as | Long bed, listed as | Series (standard / long) |
|---|---|---|---|
| 2020 to 2026 | 6'9" or 6'10" | 8' or 8'2" | 48 / 32 |
| 2015 to 2019 | 6'6" or 6'7" | 8' or 8'2" | 41 / 21 |
| 2007 New Body to 2014 | 6'6" or 6'7" | 8' or 8'2" | 34 / 14 |
| 1999 to 2006, 2007 Classic | 6'6" | 8' | 21 / 9 |
Most brands list the 2020 to 2026 beds as 6'9" and 8', while TruXedo, Roll-N-Lock and most Access parts call the same beds 6'10" and 8'2". If the selector offers both sizes for your year, check both, because they are one bed. Match the model year as well: no part here fits both a 2019 and a 2020 Sierra HD. Every 2020 to 2026 part also lists the Silverado 2500 HD and 3500 HD, which share these beds. No one-piece lid here fits a 2020 or newer truck.
GMC added the MultiPro tailgate to the Sierra HD for 2020, and most covers here list no tailgate limit (the exceptions are in the FAQ below). Owners report one snag: the grab handle bolted inside the bed beside the tailgate can crowd a cover's rail or clamp. A Sierra 2500 HD owner fitting an Extang Trifecta 2.0 wrote:
“The fit is close because my new truck has an arm to assist climbing into the back. But I moved the cover a little more to the front and everything fits fine.”

Bed-side storage boxes rule out most 2020 to 2026 Access parts, Roll-N-Lock's M-Series and one LOMAX Hard Tri-Fold part. Roll-N-Lock's 6'10" M-Series also needs the factory front tie-downs removed. On 2007 to 2014 trucks, a cargo management system in the bed rules out UnderCover's Flex, ArmorFlex and Ultra Flex, the Pace Edwards SwitchBlade and most TruXedo Lo Pro and Deuce parts.
For a fifth-wheel hitch, the spec sheets list BAK's Revolver X4s ($1,399.99) and Revolver X2 ($1,379.99) hard roll-ups as compatible with most fifth-wheel hitch setups, and both roll onto a spool at the front wall to open the whole 6'9" or 8' Sierra HD bed. A 2024 Sierra 3500 owner with the long bed chose the X2 to be sure of room for the hitch. Owners of 2024 and 2025 HD trucks also say BAK packs foam strips to shim the rails where the bed width varies.
For weight on top, the Extang Solid Fold ALX ($1,249.99) is rated for 600 lb on both 2020 to 2026 beds. The RetraxPRO MX ($2,249.99) carries 500 lb, slides into a canister at the front wall and is one of only two Retrax covers with a 2020 to 2026 long-bed part. One owner wrote:
“I bought this for my new AT4 3500. The install took 1.5 hours and was one of the easiest I have done.”

Six covers carry T-slot rails on the 2020 to 2026 long bed and ten on the standard bed. The BAKFlip MX4 TS ($1,499.99) is the hard folding choice for both. The TruXedo Pro X15 TS ($669.99) costs less, but its parts are listed only for trucks without the MultiPro tailgate.
Powered covers depend on the bed: the Retrax EQ ($2,799.99) and both PowerTraxPRO covers fit only the 6'9" bed, so on the 8 ft bed the powered choices are the Pace Edwards BedLocker ($2,886.23) and UltraGroove Electric ($3,160.55).
All the soft covers here start under $700 for the Sierra HD. The Extang Trifecta e-Series ($339.99) has the lowest From price on this page and fits the 2020 to 2026 6'9" bed, but it has no long-bed part. On that 8 ft bed, eleven soft covers from Extang, TruXedo and Access fit.
Nine brands make covers for the Sierra HD here, and all but LOMAX have parts for both 2020 to 2026 beds. The table shows one or two series from each:
| Brand | Series | Type | 2020 to 2026 beds | From |
|---|---|---|---|---|
| Extang | Trifecta 2.0 | Soft folding | 6'9", 8' | $469.99 |
| Access | Lorado | Soft roll-up | 6'10", 8'2" | $580.55 |
| TruXedo | Pro X15 | Soft roll-up | 6'10", 8'2" | $599.99 |
| UnderCover | Flex | Hard folding | 6'9", 8' | $1,149.99 |
| BAK | BAKFlip MX4 | Hard folding | 6'9", 8' | $1,249.99 |
| Extang | Solid Fold ALX | Hard folding | 6'9", 8' | $1,249.99 |
| TruXedo | Sentry CT | Hard roll-up | 6'10", 8'2" | $1,379.99 |
| BAK | Revolver X4s | Hard roll-up | 6'9", 8' | $1,399.99 |
| LOMAX | Professional | Hard tri-fold, diamond plate | 6'9" | $1,442.70 |
| Roll-N-Lock | M-Series | Retractable | 6'10", 8'2" | $1,799.99 |
| Retrax | RetraxPRO MX | Retractable | 6'9", 8' | $2,249.99 |
| Retrax | RetraxPRO XR | Retractable with T-slot rails | 6'9", 8' | $2,399.99 |
| Pace Edwards | BedLocker | Electric retractable | 6'9", 8' | $2,886.23 |
From is each series' lowest Sierra HD price, sometimes for an older model year, so the selector has the final word on your part.
The BAK Revolver X4s ($1,399.99) rolls up behind the cab to leave the whole 6'9" or 8' bed open, and its spec sheet lists it as compatible with most fifth-wheel hitch setups. Closed, it carries 400 lb with BAK's Level-3 security rating and a 5-year warranty. Skip it if you want cross bars: the Revolver X4 TS ($1,629.99) adds T-slot rails on 2020 to 2026 trucks.
The Extang Solid Fold Toolbox 2.0 ($1,249.99) sits behind a crossover box on 2020 to 2026 6'9" and 8' beds and on 2015 to 2019 6'6" and 8' beds. Its hard panels clamp on by hand and fold forward for two-thirds of the bed. Skip it if the budget stops under $700: Access's Toolbox Edition soft roll-up ($580.55) takes most 19 to 21 inch boxes on both 2020 to 2026 beds.
The Extang Trifecta 2.0 ($469.99) clamps on without tools, folds to open two-thirds of the bed and lifts off for the rest, backed by a limited lifetime warranty. It fits 2020 to 2026 6'9" and 8' beds and every 6'6" bed back to 1999, and no part in the series runs much past $500. Skip it if cargo rides on top, since its spec sheet gives no load rating; it also has no part for the 2015 to 2019 long bed.
The RetraxPRO XR ($2,399.99) has full-length T-slot rails, carries 500 lb on double-wall aluminum slats and locks with a key. It is the only Retrax with rails for the 2020 to 2026 8 ft bed and has a limited lifetime warranty. Skip it if the budget stops near $1,500: the BAKFlip MX4 TS ($1,499.99) keeps T-slot rails on both 2020 to 2026 beds at a 400 lb rating.
Folded up against the back window, the BAKFlip MX4 ($1,249.99) opens all of a 6'9" or 8' Sierra HD bed, and closed it carries 400 lb.
The RetraxPRO MX ($2,249.99) holds at any point along its track and carries 500 lb on double-wall aluminum slats, on both 2020 to 2026 Sierra HD beds.
The TruXedo Pro X15 ($599.99) rides on rails cut at 15 degrees, so the closed cover sits almost level with the bed caps on 2015 to 2019 beds like this one and on 2020 to 2026 trucks.
A 2020 to 2026 Sierra HD has either the Standard Bed (listed as 6'9" or 6'10") or the Long Bed (listed as 8' or 8'2"). Every Regular Cab has the Long Bed, and a Crew Cab can have either. On 2015 to 2019 trucks the beds are listed as 6'6" or 6'7" and 8' or 8'2". To check, run a tape along the floor from the front wall to the closed tailgate: the standard bed comes in under 7 ft and the long bed a little over 8 ft.
Most do with no special part. The TruXedo Pro X15 comes in separate 2020 to 2026 versions for trucks with and without the MultiPro tailgate, so match yours. The rack-ready Pro X15 TS is listed only for trucks without it. Most Access parts for those years are listed for either tailgate, as are Roll-N-Lock's 8'2" parts and one LOMAX Hard Tri-Fold part.
On 2020 to 2026 trucks the parts here make no dually split: each 3500 HD part is listed by bed alone, and a RetraxPRO MX owner runs one on a 2024 Silverado 3500 dually, which shares the Sierra's bed. On older duallys, read the part notes. The Pace Edwards BedLocker has an 8' part for 2004 to 2019 3500 duallys, and Access makes a dually Lorado for 2001 to 2006 trucks and the 2007 Classic. TruXedo makes dually 8'2" versions of the Lo Pro (2007 to 2014) and Deuce (2007 to 2013), while its Pro X15 and Pro X15 TS 8'2" parts for those years are listed for single rear wheels.
On a 2015 to 2019 HD, usually: nearly every part here for those years is the same part listed for the 2014 to 2018 Sierra 1500 with the same bed. The 2020 to 2026 HD's 6'9" bed has no 1500 match, so no standard-bed part crosses over. Seven 8'2" parts do, fitting both trucks' long beds: the Roll-N-Lock M-Series and six TruXedo covers, from the Lo Pro to the Sentry CT.
Mostly, by owner reports. A RetraxONE MX owner with a GMC AT4 2500 saw very little water get in through a car wash, while a Revolver X2 owner with a 2024 Sierra 3500 long bed gets a bit at the top of the tailgate. Retrax covers drain through tubes, and a 2025 GMC 2500 AT4X owner swapped the RetraxPRO MX drain tubes for 3/8 in tubing that fits the bed's stock drain holes.
