Ring & Pinion 4.86 w/o Bearings

The Ring & Pinion 4.86 w/o Bearings is designed for serious drag racers, circle track competitors, and street performance enthusiasts who require aggressive final drive ratios. This gear set is essential for vehicles optimized for quarter-mile acceleration or high-RPM track work, where every fraction of a second counts. It transforms low-end torque delivery and launch characteristics, making it a critical component for performance upgrades.

Engineered for precision, the 4.86 gear ratio enhances torque multiplication through the differential, allowing engines to reach peak power delivery at lower vehicle speeds. This is crucial for launch control and acceleration in competitive environments. The gear set is machined to exacting tolerances for smooth engagement and minimal backlash under extreme loading, ensuring reliability during high-performance use.

Ideal for those building dedicated race cars or upgrading street machines, this configuration is supplied without bearings, allowing builders to select OEM or premium bearing upgrades tailored to their specific application. The compact dimensions and weight reflect precision manufacturing that minimizes rotational mass while maintaining structural integrity under sustained high-load operation.
