Product Description

The SuperPro SPF3507K Front Upper-Inner Control Arm Bush Kit is designed to replace worn factory rubber bushings on the front upper control arms of Toyota Crown and Lexus GS/IS models. Over time, the OE rubber bushings can degrade, causing play in the control arm, reduced steering precision, and uneven tyre wear. This kit restores front suspension stability and improves handling through the use of high-quality polyurethane and steel inserts.

Installation involves removing the front upper control arm, pressing out the worn bushings, and installing the SuperPro components. Because the control arm affects suspension geometry, a full front wheel alignment is required after installation. Fitment is confirmed for the listed model years and vehicles; for other trims or post-2011 models, users should verify compatibility before purchase.
