Product Description

The Whiteline KCA313-BJ Roll Centre/Bump Steer Ball Joint Kit is a front suspension upgrade designed to correct roll-centre geometry and minimise bump steer, especially on lowered Subaru vehicles. By raising the front roll centre, this kit reduces unwanted suspension compression during cornering, improving weight distribution and tyre contact for sharper handling and enhanced grip at the front. Fitment spans a wide range of Subaru models including Forester, Impreza, Outback, Legacy, WRX/STI, Levorg, and XV across their respective compatible production years, along with select Saab 9-2X vehicles.

Built as a direct-fit service kit, the KCA313-BJ includes two high-quality ball joints designed to replace worn or stock ball joints while correcting suspension geometry. Installation typically takes around 1.5 hours, and a professional wheel alignment is recommended after fitting. This part is ideal for enthusiasts and daily drivers seeking improved handling precision, reduced understeer and more balanced front suspension dynamics without altering the vehicle's core steering geometry.
