AccuTune Offroad builds weight-specific, re-valved suspension for the full Chevy and GMC lineup: Silverado/Sierra 1500, 2500 HD, and 3500 HD, Suburban/Yukon XL, Tahoe/Yukon, Avalanche, and Colorado. Every setup starts from how the truck is actually loaded, whether that's a daily commute, a family hauling trip, or a heavy trailer. Every tuneable shock is physically re-valved in our San Diego shop using AccuTune Equations, our proprietary process for calculating the correct spring rate, motion ratio, and damping curve for your specific truck, GVWR, towing habits, and accessories.
On the 2019 and newer Silverado/Sierra 1500, Trail Boss and AT4 trims come with factory-leveled suspension already, and AccuTune carries kits built to work with that factory setup rather than against it. Fox and King shock packages are available across the lineup, with leveling kits or as part of complete systems including upper control arms; for lifts over 2", aftermarket control arms are strongly recommended to correct CV axle angle and extend the life of joints and axles.
