The Motive Gear 4.71 Ratio Ford 10-inch Ring & Pinion Gear is a precision differential component engineered for Ford 10-inch axle assemblies requiring a 4.71:1 gear ratio. This ring and pinion kit delivers the steep gear reduction needed for maximum torque multiplication in high-load applications, from off-road recovery and towing to performance drag racing where low-end pulling power is critical. Built to Motive Gear's Pro Gear specifications with a 35-spline pinion, this component offers the mechanical advantage serious enthusiasts and professionals demand when stock ratios fall short.
The 4.71 ratio represents a significant step down from factory differentials, multiplying engine torque by 4.71 times at the wheels for each complete engine rotation. This specification translates directly to faster acceleration off the line, improved towing capacity, and better hill-holding in extreme-duty scenarios. The 35-spline pinion design distributes load across a larger tooth surface, reducing contact stress and extending component life under repeated high-torque cycles. Weighing 23.33 pounds, this is a complete ring and pinion kit ready for installation into Ford 10-inch housings, with each component precision-machined to tight tolerances for smooth, quiet operation once properly set up.
This gear ratio is ideal for operators who prioritize pulling power and low-speed torque multiplication over highway fuel economy. Off-road enthusiasts running challenging terrain, commercial operators managing heavy payloads, and performance builders chasing drag strip consistency all rely on steep ratios like 4.71:1 to maximize available mechanical advantage. Installation requires professional axle work—proper setup includes backlash adjustment, bearing preload, and pinion depth shimming to ensure quiet mesh and longevity. The Motive Gear Ford 10-inch 4.71 ratio ring and pinion kit (part number F910471) is a core component for builders and shops rebuilding heavy-duty differentials to exact performance specifications.
