Performance Chromoly Axle Shafts from Sierra Gear & Axle are designed for high performance use.
For our performance axle shafts, we use 4340 Chromoly steel, which has been hardened to maximize the strength and ductility of the axle shafts. Stock axle shafts are typically made from 1040 and 1541 steel and are perfectly adequate for stock applications. The combination of superior materials and advanced manufacturing processes make Sierra Gear Chromoly axles far stronger and more durable than standard stock axles. These Performance Chromoly axle shafts are available for Jeep, Ford, GM and Dodge applications and are backed by our 10 Year Limited Warranty. In addition to our Performance Chromoly Axles, we also have axle shaft upgrades that are non-chromoly but have an increased number of splines for superior strength.
