Replace worn Mustang Cobra IRS cross-axis joints with Maximum Motorsports' spherical bearing upgrade for less than half the price of OEM Ford replacements! The IRS cross-axis joints are the pivots on the rear uprights (spindles) where the rear control arms attach. Stock replacements for the joints are only available by purchasing a complete rear hub and spindle assembly from your local Ford dealer. MM's upgraded replacement for the plastic-bushed OEM Ford joints utilizes a high-strength PTFE-lined spherical bearing. These bearings provide long service life, along with easier future maintenance. The MM kit includes tooling to aid in removing the OEM Ford joints and installing the MM replacements.

Fits 1999-2004 Mustang Cobra IRS. One kit replaces all four cross-axis joints on one Mustang.

Note: Ford recalled the 1999 model year Mustang Cobra to replace the IRS uprights because of problems with the cross-axis joints. The Maximum Motorsports kit does not fit the original 1999 uprights; only the uprights that replaced them in the recall, and the post-1999 OEM uprights. See this document about how to distinguish between the two different Mustang Cobra IRS uprights.
