Bearing Kit for 5in Spring

The ALLSTAR PERFORMANCE Bearing Kit for 5in Spring (ALL 64214) is a coil-over thrust bearing assembly designed to support and stabilize 5-inch inner diameter springs in suspension systems. This complete kit includes roller bearings and washers, engineered from steel to handle the demanding loads and repeated compression cycles typical of performance suspension applications, whether in drag racing, street performance, or off-road setups.

The roller bearing design reduces friction during spring compression and extension, allowing smoother suspension articulation and more predictable spring rate performance. Steel construction provides the rigidity and fatigue resistance required to maintain proper bearing clearance over thousands of compression cycles without deformation. The inclusion of precision washers ensures even load distribution across the bearing surfaces, minimizing side loads that can cause premature wear or misalignment. These specifications directly translate to more consistent suspension geometry and improved handling feedback on the track or street.

This bearing kit is essential for builders and enthusiasts working with coil-over suspension systems that use 5-inch springs. It serves both performance-focused applications—where suspension compliance affects lap times and vehicle control—and street builds where smooth suspension action improves ride quality and safety. The kit format eliminates guesswork about component selection, providing everything needed for proper thrust bearing installation in one package.

ALLSTAR PERFORMANCE is recognized in the drag racing and performance automotive community for suspension components that meet rigorous repeatability standards. This bearing kit represents their OEM-style specification approach: engineered around proven dimensions rather than generic aftermarket assumptions.
