Silverado / Sierra 1500 — 2019 to today
- Regular Cab — Long Box (8'2").
- Double Cab — Standard Box (6'7"); early work trucks also offered the Long Box.
- Crew Cab — Short Box (5'10") or Standard Box (6'7").
GM widened and deepened the bed for 2019, so shells and covers for 2014–2018 trucks don't carry over. In 2019 GM also sold the older truck as the Silverado 1500 LD and Sierra 1500 Limited — those use the 2014–2018 bed. Silverado 1500 sizes · Sierra 1500 sizes
Silverado / Sierra 2500HD & 3500HD — 2020 to today
Double and Crew Cab with a Standard Box (6'9"), or Regular, Double and Crew Cab with a Long Box (8'2"). 3500 duallies use the Long Box. The HD bed is its own design — it is not the same bed as the 1500. Silverado 2500HD · Silverado 3500HD · Sierra 2500HD · Sierra 3500HD
2014–2018 (2015–2019 HD)
For 2014 the old Extended Cab with small rear-hinged ("suicide") doors was replaced by the Double Cab, whose rear doors open on their own. Regular and Crew Cab carried on. HD trucks switched to the same names for 2015. Beds were the Short Box (5'8"), Standard Box (6'6") and Long Box (8'). The 1500 and HD beds of this era are the same box, which is why so many shells cross between them.
1999–2013
Chevy and GMC used Regular Cab, Extended Cab (small rear doors) and Crew Cab, with Short (6'6"), Long (8') and — on crew cabs from 2004 — an Extra-short 5'8" bed. The narrow Sportside/Stepside bed with fenders outside the box was offered through 2007. See the "Older years" tables on each model page.
