Installation summary

This suspension upgrade requires medium installation difficulty and can be successfully tackled by experienced DIY mechanics with proper garage equipment in about two hours. You will need a hydraulic shop press and specialized spring perch tools to safely extract the factory rubber bushings and press in the new spherical bearings. The most critical step is ensuring the monoballs are oriented correctly during pressing to avoid binding, and a professional wheel alignment is strictly required immediately following the installation.
