Manual steering has its charm, but tight parking lots, slow cruising, and daily driving can turn it into a workout. The CPP 400 Series kit transforms the experience, delivering smooth, confident power steering while keeping your factory column right where it belongs. Best of all, it’s designed as a true bolt-in solution, no hacking, cutting, or major modifications required.
