Step into the world of unmatched performance and superior handling with the team at Texas Truck Works. We are proud to present the ultimate upgrade for your Sprinter 3500 - Fabtech’s 1.5” Coil Assist Kit. Designed for the 2015-2021 Mercedes Sprinter 3500 4WD, Fabtech’s 1.5” Coil Assist Kit is a game-changer. It enhances your struts, empowering you to conquer rough terrains and manage heavy loads with unprecedented ease. The coil springs are strategically positioned around the strut bodies, providing an additional lift that not only increases ground clearance but also allows the installation of larger tires. But that's not all. The kit also significantly reduces sway for vans with full interior build-outs or those hauling heavy cargo. Built with 1/4" thick steel, these heavy-duty front auxiliary shock mounts attach exclusively to the suspension subframe, ensuring no attachment to the unibody structure. This method of mounting is vastly superior to other shock kits that mount to the unibody, as it isolates road noise and eliminates potential stress to the unibody. Installation is a breeze, requiring only two holes to drill and taking just 1-2 hours, with no need for interior removal. This Sprinter auxiliary shock kit, complete with Performance twin tube shocks, is the ideal upgrade for Sprinter owners seeking increased suspension damping for highway and offroad trails.
