Whiteline Rear Trailing Arm Bushing Kit Subaru WRX 02-07 / STI 04-07 / Forester XT 04-08 | W61381A

Restore precision to your rear suspension and eliminate unwanted movement with the Whiteline W61381A Trailing Arm Lower Front Bushing Kit. Engineered to replace the factory rubber trailing arm bushings in the rear lower forward position, this kit helps maintain alignment geometry and improve handling stability.

Often overlooked, the trailing arm bushings play a critical role in controlling lateral and longitudinal forces under load. Upgrading to high‑performance bushings reduces slop, tightens rear suspension feedback, and delivers more predictable behavior during spirited driving.
