Whiteline Front Lower Inner Caster Bushing Kit – 2003–2007 Honda Accord & 2004–2008 Acura TSX – KCA550

Whiteline Front Lower Control Arm Caster Bushing Kit

Improve steering response, straight-line stability, and front suspension control with the Whiteline KCA550 front lower inner control arm bushing kit.

Designed for the 2003–2007 Honda Accord and 2004–2008 Acura TSX, this kit replaces the forward inner bushings in both front lower control arms. Its dual-offset design provides approximately ±0.5 degrees of caster adjustment, allowing the bushings to be positioned to increase positive caster or help correct side-to-side caster variation.

Increasing positive caster can provide greater steering weight, improved return-to-center behavior, better straight-line stability, and increased dynamic negative camber gain while cornering. The firmer Whiteline bushings also help reduce unwanted control-arm movement under braking and cornering loads.

Installation Note

The original bushings must be pressed out of the front lower control arms before installation. The offset orientation determines the caster change, so both bushings must be positioned correctly for the desired alignment result.

Professional installation is recommended. A wheel alignment should be performed after installation to verify caster, camber, and toe settings.
