Whiteline W83404 Front Lower Radius Arm Bushing Insert Kit

The Whiteline W83404 is a front lower radius arm bushing insert kit engineered to eliminate unwanted movement and flex in your suspension's factory rubber bushings. By reinforcing these high-load locations, this kit helps tighten steering response and reduce alignment change during hard driving, all while preserving a comfortable everyday ride feel.

Rather than replacing the entire bushing assembly, these precision-fit inserts press directly into the existing factory radius arm bushings — no permanent modification required. The result is a more connected, responsive chassis with tighter handling characteristics during braking and cornering.

Key Features:

• Fills voids in factory rubber radius arm bushings for improved chassis rigidity
• Made from Whiteline's proprietary synthetic elastomer material — resistant to deformation, heat, and oil
• Delivers the compliance of rubber at low speeds while providing greater control under load at higher speeds
• Reduces alignment change and improves steering precision during aggressive driving
• Installs by pressing into OEM bushings — no permanent modification to the vehicle
• Improves braking stability by reducing bushing flex under deceleration loads
• Lifetime warranty on Whiteline bushing kits (part numbers W00001–WZZZZZ)

Whiteline is a globally recognized leader in performance and replacement suspension components, known for delivering measurable gains in vehicle balance, steering precision, and grip. The W83404 is an ideal upgrade for daily drivers and performance-focused builds alike.
