These axle and drive plate kits are designed for off-road and circle track racing applications with Wide 5 (3/4 to 1-ton truck type hubs), Dana™ 60/70 (and most Dana™ 80) hubs, and 14-Bolt style full floating hubs. The 40-spline drive flanges are manufactured using aircraft quality alloy steel and are heat-treated and black oxide coated. The axles are available in standard 4340 steel or high strength 300M steel. The center section spline is available or any spool / carrier requirements. The parts are designed to work with low-profile sealing o-rings. All sets feature MW true involute splines and are in-house heat-treated. The complete kits are comprised of shafts, flanges, caps, fasteners, o-rings, and retaining rings. Custom produced for specific application with quick delivery. 

** Note ** When planning your build, be sure to keep the factory housing and spindle dimensions in mind. Changes made to spline count could necessitate new outer parts (hubs, floater cups, brake parts, etc). In addition, you may need to have the ability to perform custom machine work and operate a welder, or be prepared to have a professional do the work for you. Specifically, anything other than 30 or 35 spline at the carrier is definitely not going to be compatible with factory style housing and spindles without modifications.
