Fabtech K7050 4-Inch Tundra TRD Ball-Joint UCA Lift Kit with Rear Performance Shocks

Fabtech K7050 is a nominal 4-inch Tundra TRD ball-joint upper-control-arm system using the factory front coilovers with spacers and two new rear Performance shocks.

Application

• 2017–2021 Toyota Tundra TRD 2WD/4WD with the 5.7L V8.
• TRD models only; excludes non-TRD and TRD Pro.

Package contents

• One complete FTS26067 component package per vehicle, including two FT70170BK front shock spacers and two FTS7188 rear Performance shocks. The factory front coilover assemblies are retained; two new dampers total, both rear.
• Two FT70222BK/FT70223BK ball-joint upper control arms, two FT20538 high-travel ball joints and the FT70225D/FT70225P steering-knuckle pair.
• Rear lift uses two FTBK12 1-inch blocks and four FT1500U U-bolts with the factory rear leaf springs. FT70195 hardware subassembly includes two FT70196 body-mount weld gussets, differential spacers, bump-stop spacers and brake-hose mounts.

Installation and requirements

• Installation requires two professional mechanics and a certified welder. The body mounts must be cut and the specified gussets welded in; tie-rod ends and front bump-stop threads require trimming.
• The factory skid plate and front mud flaps are removed. Brake hoses and wheel-speed sensor wiring require relocation and full-travel/steering clearance checks.
• Check alignment before installation, align to factory specifications afterward and recheck fasteners after 50 miles.
• The lower-control-arm shock mount requires clearance grinding. The selected front spacers fit above the retained factory coilovers; the two rear Performance shocks replace the factory rear units.

Tire and wheel guidance

• Factory wheels/tires and 17-inch wheels cannot be used. Manufacturer guidance: 35/12.50R18 or 295/70R18 on 18×9 wheels with 4-1/2-inch backspacing, or 35/12.50R20 on 20×9 wheels with 5-inch backspacing. Minor trimming is required.
