Part #: SPF3868-21K

Overview

The Superpro Sway Bar Mount To Chassis 21mm bushings are a critical upgrade for owners of the Scion FR-S, Subaru BRZ, and Toyota 86 models within the specified year ranges. These bushings serve as the essential connection points anchoring the sway bars to the chassis, directly influencing your vehicle’s handling precision and body control. Over time, the factory rubber bushings deteriorate, leading to a loose, imprecise steering feel and diminished suspension performance. Superpro’s engineered replacement bushings restore and enhance the sway bar’s effectiveness, delivering sharper cornering response and improved road feedback.

Designed specifically to fit the original equipment mounting points and hardware, these bushings ensure a perfect fit without the compromises of generic or universal kits. Whether you are a spirited driver seeking better handling or simply want to maintain your vehicle’s factory driving dynamics, these bushings offer a durable, maintenance-free solution that lasts.

Construction & Design

Superpro bushings are crafted from premium-grade polyurethane, a material known for its excellent resistance to abrasion, oil, and environmental degradation compared to standard rubber. This ensures the bushings maintain their shape and performance characteristics over extended use. The design incorporates grease retention grooves that hold lubricant within the bushing, preventing metal-to-polyurethane contact and eliminating noise and premature wear. Each bushing is molded to match the exact dimensions and contours of the factory sway bar mounts, guaranteeing a secure fit and consistent performance without the need for modifications or additional hardware.

Installation & Fitment

Installation is straightforward and designed to be a direct replacement for the original sway bar mount bushings. No special tools or modifications are required, making it accessible for both professional mechanics and experienced enthusiasts. The bushings fit the 21mm sway bars on the following vehicles:

• 2013–2016 Scion FR-S
• 2013–2020 Subaru BRZ
• 2017–2020 Toyota 86

Replacing worn bushings with Superpro units restores the sway bar’s effectiveness, improving handling stability and driver confidence.
