Performance Axle Shafts

Sierra Gear Performance and Chromoly Axle Shafts

Chromoly Performance Axles from Sierra Gear & Axle are designed for high performance use. Stock axle shafts are typically made from 1040 and 1541 steel and are perfectly adequate for stock applications.  We use 4340 Chromoly steel, which has been hardened to maximize the strength and ductility of the axle shafts. 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 axle shafts are available for Jeep, Ford, GM and Dodge applications and are backed by our 10 Year Limited Warranty.

Axle Bearing and Seal Kits can be found here
