GM 14-bolt (10.5")

The GM 14-bolt 10.5" full-float rear axle is prized for strength under heavy loads and large tires on 3/4- and 1-ton trucks. Ring and pinion sets must match your existing ratio goals, spline count, and whether the axle is full-float or semi-float.

Browse ratios suited to towing and off-road builds. Proper bearing preload and gear pattern are essential given the higher torque loads these axles see.
