SKU: K9012DL Category:



2015-21 Mercedes Sprinter 3500 4WD

Sprinter vans that have been upfitted for overlanding and/or carrying additional cargo weight often need more damping capacity than what the factory front struts, and rear shocks can provide. Fabtech addresses this problem with their heavy-duty auxiliary shock kit and Dirt Logic 2.25 shocks.

The kit retains the factory front struts and adds two high quality Fabtech built Dirt Logic 2.25 shocks with valving specific to the Sprinter van. The valving will provide a superior ride quality for both loaded and unloaded vans. The Dirt Logic 2.25 shocks are constructed with stainless steel bodies that provide maximum corrosion resistance in all conditions.

These heavy-duty auxiliary shock mounts are built with 1/4" 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.

This Sprinter van auxiliary shock kit and Dirt Logic 2.25 shocks are the perfect upgrade for Sprinter owners looking for increased suspension damping for highway and offroad trails.


  • Additional shock damping for upfitted van and/or hauling heavy cargo
  • Brackets attach to subframe for a quiet ride
  • No interior removal required for installation
  • Compatible with Fabtech Coil Assist kit
