SuperPro SPF5776K Front Lower Control Arm Bushing Kit - 4 Piece Polyurethane Set

The SuperPro SPF5776K is a front lower control arm bushing kit designed for the Jeep Wrangler JL and Gladiator JT platforms. This 4-piece polyurethane kit replaces worn OEM rubber bushings to restore and improve front suspension performance for both on-road and off-road driving.

Why Replace Your Control Arm Bushings?

Control arm bushings form the vital pivot and link between all core suspension components. Worn bushings allow excessive deflection and movement, leading to vague steering response, irregular tire wear, and reduced handling precision. The problem is amplified on modified Jeeps running larger tires, lift kits, or additional load—all of which place greater stress on suspension pivot points.

Key Features:

• Manufactured from SuperPro's proprietary polyurethane compound—significantly more durable and wear-resistant than OEM rubber
• Kit includes 4 pieces covering the front lower control arm bushing positions
• Engineered with voiding and knurling to reduce NVH (Noise, Vibration, Harshness) to near-OEM levels
• Tangential grease grooves retain lubrication longer, reducing maintenance intervals
• Resists degradation from ozone, oil, and harsh environmental conditions that cause rubber to deteriorate
• Backed by SuperPro's lifetime warranty for bushings
• Developed through nearly five decades of suspension engineering and real-world testing in demanding terrain

SuperPro polyurethane bushings are engineered to maintain correct suspension geometry under load, which is especially critical for lifted or modified Jeeps running oversized tires. By eliminating the flex and deflection of worn rubber bushings, the SPF5776K helps restore proper caster alignment, reduce tire wear, and sharpen steering response.
