QM Axle Sprocket 29t

The QM Axle Sprocket 29t by TANNER is a critical drivetrain component designed for vehicles requiring precise gear ratio calibration and torque delivery. Whether you're building a custom off-road rig, restoring a classic motorcycle, or optimizing a performance vehicle, this 29-tooth sprocket serves as the foundational element for rear-end gearing strategies. The 29t configuration is commonly selected by builders seeking moderate reduction ratios that balance acceleration response with highway cruising efficiency, making it ideal for mixed-use applications where versatility trumps specialized performance.

Engineered from durable steel and manufactured to OEM tolerances, the QM Axle Sprocket 29t features precision-cut teeth designed to mesh cleanly with your vehicle's drive pinion, ensuring smooth power transfer and minimal drivetrain noise. The compact footprint—measuring 4.9 inches in overall diameter with a 0.6-inch thickness—allows straightforward installation in stock or modified differential housings without frame or suspension interference. TANNER's manufacturing process maintains tight dimensional accuracy (MPN 75329), reducing runout and ensuring consistent engagement across the full mesh cycle, which is essential for longevity under high-torque applications.

This sprocket is ideal for enthusiasts upgrading from OEM gearing or fine-tuning existing setups to match engine output and intended use. Installation requires removal of the differential cover and careful carrier work—a task best performed by experienced mechanics or in a proper shop environment with correct tools and torque specifications. The lightweight 0.32-pound design minimizes rotational mass, contributing to quicker acceleration response and reduced bearing load compared to heavier alternatives, while maintaining the structural integrity required for modern vehicle demands.
