Fabtech FTS21274 Front Uniball Upper Control Arm Pair for GM 1500

Fabtech FTS21274 replaces the front upper control arms with a driver and passenger uniball arm pair. The package includes the associated bushings, sleeves, adapter pins, misalignments and hardware. Arms alone do not add lift; shocks and other suspension-system components are sold separately.

Verified application

• 2019–2021 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, 2WD or 4WD, with 0–6-inch suspension lift.
• 2019–2021 Chevrolet Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 pickups, 4WD, with 0–4-inch suspension lift. The standard-model 0–6-inch limit does not apply to these factory-lift models.
• Excludes the old-body 2019 Chevrolet Silverado LD and GMC Sierra Limited 1500, and vehicles equipped with Super Cruise. Confirm the vehicle configuration, lift height and shock compatibility before ordering.

Construction

• 1.50-inch OD, .120-inch wall 4130 chromoly tubing with 1-inch stainless PTFE-lined FK uniballs.
• 17-4 stainless-steel pins and misalignments, urethane pivot bushings and capped uniball cups.

Installation requirements

Professional installation and alignment are required. The FT21274 instructions require compatible Fabtech shock absorbers and removal of the factory bump-stop tabs from the frame mounts with a cutoff wheel. Follow the complete instructions, including ABS-line routing, torque checks and clearance checks; some oversized tires require bumper or valance trimming. Recheck fasteners after 50 miles and periodically thereafter.
