Rear Knuckle Bushing Kit - Mazda MX5 Miata ND

Upgrade your ND Miata’s rear suspension with this Rear Knuckle Bearing Kit, engineered to replace the factory spherical bearings with a higher-precision, zero-play solution. While the OEM bearings offer smooth articulation, they can still develop play, wear under repeated high-load use, and allow small but critical alignment changes during cornering. This Whiteline kit utilizes premium motorsport-grade spherical assemblies designed for maximum durability, minimal friction, and absolute consistency at the limit. By eliminating bearing slop and unwanted compliance, this upgrade ensures precise suspension geometry, sharper feedback, and the confidence to drive your tires to their full potential grip—lap after lap.
