All of our kits are a direct bolt in and require no modifications to your vehicle. These kits work with your OEM shocks and retain the stock ride quality of your truck. Every Truxxx GM2500 1.0″ block and u-bolt kit has 3/4″ U-bolts that are made with US high chromium steel rod ( cheaper off shore steel has little to no chromium and can stretch, causing your axle to come loose) and blocks that have been fabricated with US and Canadian mill certified steel, laser cut to precision tolerances using OEM drawings. Each 1.0″ block kit is welded using the latest US Made welders and triple checked to ensure proper fitment. Recommended installation time is approx 1 hour and this kit can be used with stock length aftermarket or original equipment shocks.
