Installation and requirements

• Professional installation required. Read the exact FTS26133, spacer-kit and FTS26132 differential-drop instructions before work; inspect the stock suspension and record factory alignment.
• Retain the factory front coilovers with the supplied spacers. The front strut studs must be trimmed to the specified 3/4-inch retained length; follow the spacer instructions and their mounting sequence.
• Install the ball-joint arms with barrel gussets upward and the specified bushings, sleeves, washers, caps and ABS-line clamps. Follow the arm guide for air-box/computer-module removal and reinstallation.
• Support and reposition the front differential using the supplied driver/passenger brackets, bushings, sleeves and backing plate; relocate the differential sensor-wire bracket as instructed.
• Follow the air-suspension branch: safely deflate and disconnect the air springs as instructed. Cut the lower air-spring mounting stud, drill its location to 7/16 inch, then mark and drill the second 7/16-inch spacer-mount hole on each side. Fit the correct driver/passenger spacers.
• Install the supplied driver/passenger height-sensor brackets, reposition the adjustment rods as specified, and reconnect the factory air lines. Follow the exact air-suspension procedure; do not substitute the rear-coil spacer branch.
• Cut the rear bumpstop brackets and install the supplied extensions and brake-line brackets. Fit both rear Stealth shocks using the specified lower-mount spacers and sleeves.
• For 35-inch tires, the instructions additionally require body-mount cutting and welding the supplied reinforcement plates. Other wheel/tire combinations may require trimming; check actual clearance.
• Check brake hoses, ABS wiring, tire and suspension clearances through steering and suspension travel. Align to factory specifications, adjust headlights, and recheck fasteners after 50 miles and periodically.
