How long is a 2500hd crew cab long bed?

In short, a Chevrolet (GMC) Silverado 2500HD with a Crew Cab and long bed is a sizable pickup, typically around 250 to 260 inches in overall length. The long-bed variant adds roughly 15 inches to the length compared with the standard-bed version. Exact numbers vary by model year and drivetrain.


Bed length options and overall length


Two bed lengths are offered for the Silverado/Sierra 2500HD line. The crew cab long bed configuration uses the 8-foot bed, which increases the vehicle’s total length compared with the shorter bed option.



  • 6.75-foot bed: 81 inches long

  • 8-foot bed: 96 inches long


Because the crew cab long bed uses the 8-foot bed, the overall length of the vehicle is extended by about 15 inches relative to the 6.75-foot bed variant. As a result, you can expect the crew cab long-bed Silverado 2500HD to sit in the roughly 250–260 inch range, depending on year and drivetrain.


Why exact length varies by year and trim


GM updates styling, bumpers, towing hardware, and other components over different model years, which can shift the precise overall length by a few tenths or a couple of inches. For a truly exact figure, consult the official specifications for the specific year and trim you’re considering.


How to verify exact length for a given year


To obtain the precise overall length of a 2500HD Crew Cab Long Bed for a specific year, check:



  • The official Chevrolet/GMC specifications page for Silverado 2500HD

  • The vehicle’s window sticker (Monroney label) for that year

  • The owner’s manual or a dealer’s spec sheet


If you share the exact model year and whether you’re looking at 2WD or 4WD, I can provide the precise measurement for that configuration.


Summary


Overall, a 2500HD Crew Cab with a long bed is typically about 250–260 inches long, with the 8-foot bed adding roughly 15 inches over the standard 6.75-foot bed. For a precise figure, reference the official specs for the exact year, trim, and drivetrain you have in mind.
