304 Offroad is based in West Virginia and builds spring kits and suspension upgrades for UTVs and side-by-sides. The lineup includes tender spring kits, long travel spring kits, dual rate spring kits, and portal gear lift spring kits, with options built around Walker Evans and Fox shocks.

Fitments cover the Polaris RZR (XP 1000, XP Turbo, Pro XP, Pro R, Turbo R), Can-Am Maverick X3, and Honda Talon, in 2-seater and 4-seater configurations. 304 Offroad's approach: you build it, you break it, they help you fix it.
