The Circuit Werks Hardened Front Lower Control Arm Bushings are designed as performance-oriented replacements for the factory rubber bushings on compatible Lexus IS, GS, and LS models. Using hardened, high-strength, anti-crack performance rubber, these bushings provide a firmer connection at the front lower control arms while retaining the ride and noise characteristics of a rubber bushing design.

Rated at Shore 70A compared with the approximately Shore 60A factory bushing specification provided by Circuit Werks, these bushings are approximately 20% stiffer than OEM. The firmer construction is designed to reduce unwanted control arm movement and provide increased steering response and suspension stability without switching to polyurethane bushings.

20% Stiffer Than OEM: Circuit Werks rates these bushings approximately 20% stiffer than the factory bushings for increased suspension control.

Shore 70A Hardness: Uses a Shore 70A performance rubber compound compared with the Shore 60A OEM specification provided by Circuit Werks.

Hardened Performance Rubber: Replaces the softer factory rubber bushings with a firmer, high-strength rubber compound designed for performance-oriented suspension use.

Anti-Crack Rubber Construction: Uses a hardened rubber material designed for strength, durability, and long-term service.

Improved Steering Response: The firmer bushing design reduces unwanted compliance at the lower control arm, helping provide more direct steering response and feedback.

Increased Suspension Stability: Designed to provide a more controlled connection between the front lower control arm and chassis compared with softer or worn factory bushings.

Rubber Instead of Polyurethane: Maintains a rubber bushing design for enthusiasts who want increased firmness without the squeaks or additional noise that can occur with some polyurethane bushing applications.

Direct OEM Replacement: Designed as a direct replacement for the compatible factory front lower control arm bushings.
