SPC Performance 15641 X-Axis Sealed Flex Joint Suspension Control Arm Bushing

The SPC Performance 15641 X-Axis Sealed Flex Joint is a high-performance bushing replacement engineered for race and off-road suspension builds. Designed as a direct replacement for many OE-style bushings, the xAxis flex joint delivers superior compliance control, enhanced articulation, and long-lasting durability compared to standard rubber, polyurethane, and spherical bearing alternatives.

This Builder Series unit features a 14mm bolt bore (I.D.), 40mm outer diameter, and 50mm width, with 20 degrees of angularity — making it ideal for high-demand suspension linkage applications where standard bushings fall short.

Key Features:

• Reduced compliance and deflection compared to rubber and polyurethane joints for more precise suspension response
• Improved durability over traditional spherical bearings and poly joints
• Increased joint angularity vs. rubber and urethane bushings — up to 20° for this application
• Sealed design retains grease and repels dirt, mud, and moisture for long service life
• Highly polished nickel-finish ball maximizes wear resistance and smooth articulation
• Easier installation compared to pressed-in rubber or polyurethane bushings
• Specifications: 14mm I.D. × 40mm O.D. × 50mm Width

The SPC xAxis Sealed Flex Joint is a proven technology upgrade for performance suspension systems, delivering consistent handling characteristics whether on the track or the trail. Suitable for use in control arms, links, and other suspension pivot points requiring a sealed, high-angularity bushing solution.
