Product Details
Description
Upgrade the front suspension on your 2007–2021 Toyota Tundra with the Tuff Country 50931 Uni-Ball Upper Control Arm Kit. Engineered for 2–4 inch lifts, it delivers improved articulation, better geometry, and enduring durability for enhanced on- and off-road performance.
- Uni-Ball joints: High-quality Teflon-lined FK uni-ball joints replace factory ball joints to dramatically reduce binding and increase articulation.
- Lift compatibility: Designed specifically for 2–4" front lifts to restore proper geometry and improve handling on lifted Tundras.
- Articulation boost: Delivers approximately 30–35% more articulation than standard ball joints, enabling smoother suspension travel over rugged terrain.
- Durable construction: Powder-coated black finish with gusseted connecting points for added strength and long-lasting performance.
- Bushings & lubrication: Polyurethane bushings paired with zerks provide easy lubrication and durable resilience in harsh conditions.
- Fitment & wheels: Front upper control arms for 2007–2021 Toyota Tundra 2WD/4WD; designed to work with factory steering knuckles and wheels with 5.5" backspacing or less; excludes TRD Pro.
- Made in the USA & warranty: Proudly manufactured in the USA with a lifetime warranty from Tuff Country, backing your lift with proven reliability.
This Uni-Ball UCA kit is built to reduce the plate‑to‑frame binding that can occur with stock ball joints, delivering more consistent steering feel and predictable handling as you flex through rocky trails or rough backroads. The geometry correction helps maintain proper wheel alignment under load, which translates to improved stability, steering response, and tire contact with the ground. With sealed, durable components and easy-to-service zerks, you’ll enjoy reliable performance and easier maintenance for years to come.
