Product Description

The SuperPro KIT131NAK Suspension Bushing Kit is designed to completely refresh the suspension system on Mazda MX-5 Miata NA and NB platforms. Over time, factory rubber bushings degrade, causing vague steering response, increased suspension movement, and inconsistent handling. This SuperPro kit replaces those worn components with high-performance polyurethane bushings engineered for improved durability and chassis control.

By reducing suspension flex and maintaining consistent geometry, the KIT131NAK kit improves steering feedback, cornering stability, and braking response. The advanced polyurethane formulation resists oil, road debris, and extreme temperatures, providing a longer service life than standard rubber bushings. This makes it an ideal upgrade for enthusiasts restoring classic Miatas, building track cars, or simply improving daily driving performance. A professional installation and alignment are recommended after installation to ensure proper suspension geometry and optimal tire wear.

Fitment confirmed for Mazda MX-5 Miata models from 1990 through 2005 across both NA and NB platforms with 1.6L and 1.8L engines. No official manufacturer confirmation currently lists compatibility beyond 2005.
