These Evolution series rear axle kits are designed, engineered, and manufactured to be the best axles on the market. The axles are made from a super-tough, induction-hardened alloy, and many feature more splines for extreme duty and dual bolt patterns for upgrading to larger studs. Plus, all axles are made using a cold-formed, rolled spline process, making them 35 percent stronger than cut splines.
