Product Description

The Whiteline KBR21-27 Heavy Duty Rear Sway Bar Mount Kit is engineered to strengthen the rear anti-roll bar mounting points on select AWD Subaru vehicles and certain Saab derivatives by replacing the stock mounting brackets and bushings with a more rigid, high-strength kit. Factory mounts can flex or twist under increased sway bar loads - especially with larger 27 mm aftermarket bars or firmer suspension setups. This upgraded mounting kit improves sway bar response, reduces compliance, and enhances rear suspension control for tighter handling and improved stability around corners and during spirited driving.

Designed for use with 27 mm rear sway bars, the KBR21-27 kit includes synthetic elastomer D-bushings and alloy mounting hardware with a durable powder-coated finish for long-lasting performance in harsh conditions. Installation is straightforward for experienced technicians or DIY enthusiasts, and all necessary hardware is included. Whether you're upgrading from stock mounts or installing a performance rear anti-roll bar, this kit helps ensure maximum sway bar effectiveness and firmer rear chassis tuning.
