Quality OE Replacement Axles with High Grade Steel

An axle shaft is the final part of a differential the transfers power to the wheels.

Front and rear axle shafts have different construction details than rears.

Front vs Rear

While a rear axle mates to the wheel via a flange on the end; a front axle consists of two shafts: an inner and an outer, that mate to each other via a universal joint to allow for turning. Front axles connect to the hub assembly.

Stronger than OEM

Factory axles are typically made from 1040 alloy steel, while aftermarket performance driveshafts are made from 1541H or 4340 Chromoly alloy for significant strength gains.
