Revolution Gear & Axle GM 14-Bolt 10.5in 30 Spline 4.10 Ratio & Down Full Spool

The Revolution Gear & Axle RGA75-2023-30 full spool is designed for GM 14-bolt 10.5-inch rear axles using 30-spline axleshafts. Built for dedicated off-road, drag racing, and competition applications, this spool locks both axleshafts together to deliver consistent torque distribution and dependable traction in demanding conditions. It is intended for vehicles where maximum drivetrain strength and predictable power delivery are more important than street-oriented maneuverability.
Designed for differential applications with a 4.10 gear ratio and numerically lower ratios, this full spool provides a direct, durable alternative to an open differential or limited-slip unit. The Revolution Gear & Axle construction supports high-load use and helps minimize differential-related wear points by using a solid carrier design. Proper axle compatibility and professional installation are essential for reliable performance, and the finished assembly should be set up according to the vehicle manufacturer’s specifications.
