If you’re running a Ford 8.8-inch rear axle and want a direct bolt-on upgrade that maximizes torque multiplication without compromises, this kit gives you the exact gearing ratios that serious builders depend on. The 30-spline pinion ensures compatibility with high-horsepower applications while maintaining proven durability.
