SPC Performance 87550 Lincoln Xaxis Joint Set (4)

The SPC Performance 87550 xAxis Sealed Flex Joint Set is a complete four-piece replacement kit for worn rear lower control arm cross axis ball joints. Engineered to restore and retain original chassis design parameters, these joints are a direct upgrade over OEM-style rubber bushings, offering reduced compliance and deflection alongside improved durability compared to standard spherical bearings and polyurethane bushings.

Key Features:

• Highly polished electroless nickel-plated balls for maximum wear resistance and long service life
• Moly-impregnated nylon races provide low-friction, smooth articulation under load
• Sealed dust boots lock out dirt, road grime, and moisture to protect joint integrity
• Pre-greased and maintenance-free design for hassle-free installation and long-term reliability
• Up to 45° of angularity accommodates high misalignment requirements — ideal for performance, race, and off-road applications
• Complete kit includes four (4) xAxis Sealed Flex Joints and two (2) press tool adapters for full rear-end service

SPC Performance xAxis joints are recommended when higher joint angularity performance is desired, making this set well-suited for performance street builds, track cars, and off-road applications where OEM bushings fall short. The included press tool adapters make installation straightforward without the need for specialty shop equipment.
