The GM 10.5" full-float 14-bolt axle is renowned for its strength because the axle shafts only transmit torque — they do not support vehicle weight. The load is carried by the spindle and dual wheel bearings, making this axle ideal for extreme use.
Thick gear options allow lower ratios to be installed on 4.10-and-down carriers without changing the carrier or locker, making them a popular upgrade for high-torque builds.
Important Note:
Thick gears are designed for 4.10-and-down carriers/lockers. Always verify axle type, carrier break, and build specifications before ordering.
