Installation Notes and Tips

Verify the stabilizer bar diameter before installation to confirm the 24.20 mm application. Inspect the mounting bracket and surrounding hardware for wear or damage before reassembly, since the bracket is not included with this kit. Clean the bar surface and mounting area so the new bushings seat correctly, and follow the vehicle service procedure for front suspension disassembly and torque specifications.
