Ring Gear - GM 168 Tooth

The Pioneer Ring Gear - GM 168 Tooth is a heavy-duty flywheel ring gear designed specifically for General Motors differentials and transfer cases, where precision gear meshing is crucial for optimal drivetrain performance. This component is essential for mechanics engaged in rebuilding GM differentials, changing gear ratios, or restoring worn drivetrain assemblies.

The 168-tooth configuration is a common OEM and aftermarket standard, making it a reliable replacement for stock and modified GM axle assemblies found in trucks, SUVs, and performance vehicles. Ring gears serve as the stationary member of a differential's gear set, meshing directly with the pinion gear to effectively transmit rotational force from the driveshaft to the axle shafts. Manufactured to OEM tolerances and material specifications, this ring gear ensures tooth geometry that resists wear, pitting, and deflection under load.

The 168-tooth count provides a direct 4.11:1 ratio when paired with a 41-tooth pinion, making it ideal for highway cruising while still offering sufficient torque multiplication for towing or off-road use. Precision casting and CNC finishing guarantee smooth, quiet operation and a long service life, which is critical for rebuilding a differential that will endure sustained RPM or aggressive driving. This ring gear is compatible with most GM 10-bolt and 12-bolt differentials, but verification against your specific axle casting and pinion configuration is essential before purchase.
