A Small Bushing With a Big Influence on Stability

Worn front control arm bushings have a huge influence on vehicle stability, steering precision, and braking efficiency, far more than their modest size and cost would suggest. As these bushings age and degrade, the control arm loses its precise, designed geometry, introducing play that shows up as vague steering, inconsistent braking feel, and reduced overall stability. Replacing them restores the front suspension to as-new condition rather than trying to compensate for the play elsewhere. It's the kind of upgrade that quietly improves everything else in the suspension too.

Built From Materials Chosen for Longevity

This service kit uses Whiteline's advanced synthetic elastomer bushings, engineered with core characteristics that ensure superior elasticity, memory, and outright durability across all forms of driving applications. That combination of elasticity and memory means the bushing continues performing consistently over years of use rather than gradually sagging or losing its shape the way a lesser rubber compound would. It's a proper repair, not a temporary fix. That's real, functional engineering, not just a marketing claim.

This is the service kit specifically for Whiteline's Control Arm Lower Inner bushing, part number KCA361.

Straight From Subispeed

A genuine restoration of front-end precision and stability for 2002-2007 WRX / 2004-2007 STI / 1990-2004 Legacy, not a temporary patch for worn control arm bushings.
