Fabtech FTS21283 Uniball Upper Control Arm Kit for 6" Lift Systems

Fabtech's Uniball Upper Control Arms are designed to replace the factory ball joint arms to strengthen the front suspension for aggressive offroad use. Compatible with 2020-2024 GM Sierra/Silverado 2500HD and 3500HD 4WD trucks, these heavy-duty control arms are engineered to work with stock height vehicles or with Fabtech's 6-inch lift systems.

Premium Construction Features:

• 1.50" OD, .120" wall 4130 chromoly tubing with 1" diameter Stainless Steel FK Uniballs
• 17-4 stainless steel pins that attach to the factory spindle taper without modification for easy installation
• Large urethane pivot bushings at the frame help to reduce chassis noise and vibration
• Additional one degree of caster when running oversized tires for improved handling and alignment
• Chromoly tubing construction reduces flex found in stock arms for enhanced road feel

Kit Includes: Driver and passenger side upper control arms (FT20929 and FT20930), uniball pins (FT94521), misalignment spacers (FT90152, FT90153), caps (FT90154), and all necessary hardware for installation.

These professional-grade uniball upper control arms eliminate the weak factory ball joints with super strong 1-inch ID stainless steel American FK uniballs, providing significantly increased suspension strength and durability for trucks that see hard off-road use or carry heavy loads. The heat-treated 17-4 stainless steel construction ensures long-lasting performance in the most demanding conditions.
