Fabtech K9012 Auxiliary Front & Rear Performance Shock Kit — 2015–2021 Sprinter 3500 4WD 3.0L V6

Fabtech K9012 adds two auxiliary front Performance shocks and replaces the two rear shocks with Performance shocks while retaining the factory front struts.

Application

• 2015–2021 Mercedes-Benz Sprinter 3500 4WD, 3.0L V6, with factory suspension and the factory front hub adapters shown in FT28002. Verify year, engine, model, drivetrain and hub configuration before ordering.
• This listing covers the 3.0L V6 configuration only. Sprinter 2500, other engines, 2WD and later AWD applications are outside this listing.
• Factory front struts are retained. No coil-assist springs or rear lift blocks are included; this auxiliary package does not provide a suspension lift.

Package contents

• One FTS28001 front auxiliary mount kit: driver and passenger upper and lower mounts with specified installation fasteners.
• One FTS28002 front hub-spacer kit: two FT19007 spacers, twelve M14-1.5 × 65mm bolts and specified thread-locking compound. Fits behind the factory front hub adapters; factory wheel lug nuts are retained.
• Two FTS7163 front auxiliary Performance shocks and two FTS7231 rear Performance shocks: four shocks total. No struts, coil-assist springs or rear block kit included.

Installation and requirements

• Professional installation required on a stock vehicle. Read FT28001 and FT28002, inspect the suspension and check alignment before installation.
• FT28001 requires two 17/32-inch drilled holes at each upper mount, four holes total. Remove the inner fender liners; trimming may be required. Follow the specified subframe and lower-control-arm mounting procedure.
• Remove the factory front hub adapters, install the FTS28002 spacers behind them and refit the adapters using the supplied bolts and thread-locking compound. Follow all specified torque values.
• Check tire, brake-hose and ABS-wire clearances through steering travel, align to factory specifications and adjust headlights. Recheck fasteners and wheel hardware after 50 miles and periodically as directed.
