SPL Pro Suspension SPL RKB ND Rear Knuckle Bushing Kit for Mazda Miata ND

The SPL Rear Knuckle Bushing Kit for the ND Miata provides a smooth articulating, deflection and compliance eliminating solution to take all of the street-car mushiness out of the rear of your suspension. The rear knuckle bushings in the ND Miata are rubber injected bushings with metal sleeves that provide a compliant ride, but this is not what you desire when pushing the vehicle to its limits.

When pushing the car to the limit, the OEM bushings will bind and deflect causing unwanted changes to your alignment as you round corners, making it difficult to hold the car at peak grip. Replacing with a full spherical solution will eliminate all artificial spring rate and mushiness from the rear of your suspension, and allow you to drive the tires to their full potential grip.

Key Features:

• Replaces rubber factory bushing with low friction teflon-lined spherical bearing for less deflection under heavy load and less bind as the arm travels through its suspension
• Uses the largest possible FK bearing in this location for increased longevity and lower NVH
• Housing machined from 6061-T6 aluminum and CNC cut to +/- .001" tolerance to insure proper fitment
• Proudly designed and built in the USA
• Sold as a pair

This kit is designed for high performance street and track applications where precise suspension control is critical. The spherical bearing design provides smooth articulation while eliminating the compliance issues found in rubber bushings, resulting in more predictable handling and improved tire grip at the limit.
