SPL Parts Rear Knuckle Spherical Bushing Kit for 2016-2025 Mazda MX-5 Miata & Fiat 124 Spider
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2016-2025 Mazda MX-5 Miata and 2017-2020 Fiat 124 Spider.
The SPL Parts Rear Knuckle Bushing Kit (SPL RKB ND) provides a precision-engineered solution to eliminate the suspension deflection and compliance inherent in factory rubber bushings. By replacing the OEM rubber-injected bushings and metal sleeves with a full spherical solution, this kit removes the "street-car" mushiness that compromises handling during aggressive driving.
Standard rubber bushings bind and deflect under heavy cornering loads, leading to unpredictable alignment changes and reduced contact patch stability. These spherical bearings provide smooth articulation without adding artificial spring rate, ensuring your suspension geometry remains consistent so you can drive your tires to their full potential grip.
- Replaces compliant factory rubber knuckle bushings with high-precision spherical bearings
- Eliminates suspension binding and unwanted deflection
- Provides consistent alignment geometry under high cornering loads
- Full spherical bearing design for zero-compliance articulation
- Proudly engineered, manufactured, and assembled in the USA
- Manufacturer Part Number: SPL RKB ND
