Save yourself 70 lbs over a stock housing! All of our housings are made with 4130 chromolly bodies and braces. The axle tubes are 3.250" OD .3125" wall DOM tubing. All of our housings are jig built with bearing cap locators, and all faceplate studs installed post weld out for a perfect fit every time. We use Rockwell 106 spindles and hubs on everything larger than a Ford 9". Our billet spindles are bored to accept 2.060" axles, and all aftermarket components fit as well. We will be glad to custom build you a housing to fit your needs from Dana 60's and Ford 9"'s to the Rockwell 106's, SQHD's, and the bigger yet 20145. We are direct with all axle and center section manufacturers so we can finish these as far as you would like us to go.
