About 3800 Parts

Chevy 3800 parts fit the one-ton Advance Design truck, the heaviest of the AD line - dually rear axle on many, longest wheelbase, and the same cab as the 3100 and 3600.

Because the cab is shared, most of what we build for the 3100 fits: smooth firewalls, floor and kick panels, billet door handles, dash and gauge panels, power window kits, and hidden fuel filler options. Bed and chassis parts are one-ton specific, so read the fitment notes rather than assuming a 3100 bed part carries over.
