Product Description

The Superpro SPF5538K is a rear suspension bearing kit designed for Mazda MX-5 Miata ND and Fiat 124 Spider platforms. It replaces factory rear control arm joint assemblies with precision-engineered polyurethane-supported bearings to improve suspension accuracy and durability.

By reducing deflection in the rear link and knuckle connection points, this kit enhances handling stability, improves alignment retention under load, and reduces wheel hop during aggressive driving or acceleration. The result is sharper rear-end response and more consistent traction performance.

Manufactured using Superpro's advanced engineering-grade materials, the kit is designed for long-term durability in both street and performance applications, offering a significant upgrade over OEM rubber-based components.
