12 Bolt Assemblies
In sheer numbers alone, the Chevrolet 12 bolt rear end is the most popular in racing. With the proper components and modifications, the 12 bolt can be strengthened to the point where it is adequate for most moderately powered full-bodied racecars. Using MW's 35-spline axle/spool package and the addition of the DTS Express (KTRE) housing will extend the life cycle of the 12 bolt. These housings feature improvements over the original GM housings that include ductile iron castings, 4130 tubes, 3.062" or 3.250" main bore caps with 1/2" bolts, and jig fitted suspension brackets. Three basic units are available; configureations include street / strip with Eaton™ posi-traction units, standard drag race with 35-spline steel spool and lightweight 35-spline aluminum spool. Bolt-in models are available for all popular GM cars including the F-body with torque arm mounts.
