Upgrade your lifted GM full-size truck or SUV with the Tuff Country 10931 Uni-Ball Upper Control Arm Kit. Designed for 2–4 inch front lifts, this UCA kit enhances suspension articulation, improves handling, and reduces binding compared to factory ball joints.
- Uni-ball joints with teflon lining: High-precision FK uni-ball joints deliver smooth, consistent movement and reduce binding under articulation.
- 30–35% more articulation: Significantly increases suspension travel for better off-road grip and smoother descent over rough terrain.
- 2–4 inch lift compatibility: Specifically engineered to restore proper geometry when your Silverado 1500, Suburban 1500, Tahoe, or GMC Sierra/Yukon is lifted in this range, improving alignment and ride quality.
- Polyurethane bushings and zerk fittings: Durable, low-maintenance bushings with simple lubrication to extend service life.
- Durable, powder-coated, gusseted construction: Strong aluminum OE-style or stamped two-piece steel arms finished for corrosion resistance and lasting performance.
- Made in the USA: Trusted manufacturing from a brand with decades of suspension expertise behind every kit.
- Lifetime warranty: Backed by Tuff Country’s warranty program for lasting confidence in your lift project.
- Direct-fit for factory knuckles: Designed to work with 2014–2018 Chevrolet Silverado 1500, Suburban 1500, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL 1500 models equipped with aluminum OE upper arms or stamped two-piece steel arms.
- Wheel backspacing requirement: Requires a wheel backspacing of 4.5 inches or less; some factory rims may not fit without checking clearance.
These Uni-Ball upper control arms restore proper geometry after lifting, providing improved steering stability, better tire contact, and enhanced on- and off-road confidence. The kit’s teflon-lined uni-balls tolerate high articulation without the harsh wear of traditional ball joints, while the rugged finish and gusseted joints stand up to daily driving and rough terrain alike. Ideal for weekend warriors and enthusiasts who demand predictable handling from their 2–4 inch lifted Silverado 1500, Suburban 1500, Tahoe, Sierra 1500, or Yukon setups.
