Product Description

The SuperPro SPF2678K bush kit is engineered specifically for the rear upper-inner control arm mount positions on the Mazda RX-7 (FD series, 1992-2002). By replacing the factory rubber bushing with a high-performance polyurethane equivalent, the kit significantly reduces unwanted control-arm pivot deflection under load, improves alignment retention, sharpens handling feel and reduces premature tyre wear.

Whether you're restoring your RX-7 to optimal condition, using it for weekend performance drives, or running modified suspension, this kit delivers tangible improvements in rear end stability and durability. Installation is straightforward for a qualified technician - remove the original bush, press in the new polyurethane kit, insert the sleeves, torque to specification, and complete a full rear-wheel alignment to capture the full benefits.

Before purchase, please verify your vehicle's exact year, model, drivetrain (RWD), and rear suspension arm configuration to ensure compatibility. While fitment through 2002 is supported, compatibility beyond those years or for other makes/platforms is unconfirmed at time of listing.
