Product Details
This Whiteline Front Lower Radius Arm Bushing Kit fits the 2007-2008 Audi RS 4. Application note: Adds +/- 0.5 degrees Caster. You receive 2 shell bushings, 2 tubes, an install guide, and grease. The part number is KCA422. This part is for the front of the vehicle.
This kit does more than replace rubber. Its offset design moves the pivot point of the lower control arm to add positive caster and change how the front end resists dive under braking, which improves straight-line stability and turn-in feel.
Installation is rated difficult, with about 3 hours of work listed. Get the car aligned once it is back on the ground. To go with it on the RS 4, see 16mm Rear Sway Bar Bushing Kit.
Features
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Finish: Powder coating covers the metal for protection against chips and rust.
- Bonded design: The bushing is bonded for strength where loads are highest.
- Grease: Molybdenum disulfide grease is included to help the parts last.
- Corrosion protection: Rust protection comes from plating on the metal parts.
