DESCRIPTION:
Engineered for Real-World Performance.
The Kryptonite Upper Control Arm Kit is a heavy-duty upgrade engineered to outperform your stock GM upper control arms in every way. Built from high-strength boxed steel, laser cut and TIG welded in the USA, these arms are a direct fit upgrade that improves strength, alignment control, and suspension travel.
Whether you're running stock suspension or have a mild to moderate lift, these control arms are designed to correct upper ball joint angles, reduce binding, and ensure long-term durability. Kryptonite UCAs also feature premium bolt-in ball joints and polyurethane bushings—pre-greased and ready to install.
If your factory arms are worn out or your lifted truck feels sloppy up front, this is the upgrade you’ve been looking for.
INCLUDES:
- 1 x Kryptonite Upper Control Arm Pair
- 4 x Control Arm Sleeves
- 8 x Control Arm Polyurethane Bushings
- 2 x Kryptonite Bolt-in Upper Ball Joints
- 1 x Complete Hardware Package
