Fabtech K9002 supplies coil-assist hardware, the Sprinter 2500 rear kit and front wheel spacers without struts or shocks. The B4 installation configuration requires compatible Bilstein B4 front struts and specified Fabtech rear shocks, purchased separately.

Application

• 2015–2021 Mercedes-Benz Sprinter 2500 4WD with factory suspension configuration. Verify the year, model and drivetrain before ordering.
• This 2500 package uses the FTS28009 rear kit. Sprinter 3500, 2WD and later AWD applications are outside this listing.
• Nominal 1.5-inch system; the manufacturer describes approximately 1–1.5 inches of front lift. Actual stance depends on the vehicle and load.
• This listing is for installation with separately purchased, compatible Bilstein B4 front struts; factory front struts are not suitable.

Package contents

• One FTS28012 front coil-assist kit: two coil springs, upper/lower spring perches, support washers and specified subassembly. No front struts, rear shocks or auxiliary shocks are included.
• One FTS28009 rear box: two replacement rear blocks, four U-bolts, two bumpstops, spacers, brake-line/linkage brackets and specified installation hardware. The physical 4-inch blocks replace factory blocks; they do not add 4 inches of net lift.
• One FTS28011 front wheel-spacer kit: two wheel spacers, twelve extended studs, twelve lug nuts, socket and specified thread-locking compound. Rear wheel spacers are not included; order one additional FTS28011 kit separately for the rear.
• Compatible Bilstein B4 front struts and specified Fabtech rear shocks must be purchased separately before installation. No dampers are supplied.

Installation and requirements

• Professional installation required on a stock vehicle. Read all supplied instructions, inspect the suspension and check alignment before installation.
• Retain the factory upper strut mounts. Install the spring perches, support washers and coils in the order shown in FT28003.
• Follow FT28009 for rear blocks, U-bolts, brake-line/linkage brackets and bumpstops. Fit one supplied FT120 spacer behind each upper rear shock mount as specified.
• Follow FT28011 for front wheel spacers and extended studs. Check tire, brake-hose and ABS-wire clearance through steering travel, align to factory specifications and adjust headlights.
• Recheck fasteners and wheel hardware after 50 miles and periodically as directed by the manufacturer.

Tire and wheel guidance

• Manufacturer reference: 275/75R16 tires with 16×8 wheels and 6-inch backspacing, with minor trimming. Verify wheel and tire clearance on the actual vehicle; wheels and tires are sold separately.
