Sprinter vans that have been upfitted for overlanding and /or carrying additional cargo weight often need more damping capacity than what the factory struts and shocks can provide. Fabtech addresses this problem with our heavy-duty auxiliary shock kit. These heavy-duty front auxiliary shock mounts are built with 1/4 in. thick steel and attach to the suspension subframe only. There is no attachment to the unibody structure. This type of mounting is vastly superior to other shock kits that mount to the unibody. By mounting to the subframe it helps isolate road noise and eliminates potential stress to the unibody. With only two holes to drill for installation it takes about 1-2 hours with no removal of the interior required.
