MX-5 / Miata NC / RX-8 Spherical Bearings for rear knuckle / upright

Replacement rear knuckle spherical bearings (that connect to the rear lateral link arms) to replace the standard rubber bushing that often degrade over time. These are track-focused replacements that provide many benefits over typical polyurethane bushes available in the market.

Benefits over rubber or polyurethane bushings:

• Decreased deflection - improving handling and steering response.
• Minimise alignment drift.
• Increased rigidity over stock bushings or polyurethane.
• Reduced friction bearings with Teflon liner between ball and body.
• Improved damping in the full range of motion of the control arm.

Features:

• No modifications to the chassis or standard mounting points required.
• CNC machined from 7075 T6 aluminium.
• Bearings come pre-assembled in assemblies.
• What you get: 2 7075 T6 aluminium spherical bearing housings.
• 2 high-quality, pre-installed motorsport spherical bearings.
• 2 internal snap ring to retain bearing in housing.
• 4 Stainless steel 316 spherical misalignment spacers.

These require a retaining compound (such as Loctite 603) to be used when installed in the rear knuckle and we advise you key the mating face prior to installation. We recommended using a hydraulic press rather than a vice or bearing installation tool to eliminate misalignment and galling. We can offer an installation service should you not have access to the tools to carry this out. These are intended for track-focused / race car use where suspension geometry is paramount over NVH (Noise, Vibration and Harshness).
