Our Builder Series housings are for those on a budget or looking to do a lot of the work themselves to keep the costs down. Also for the customer that doesn’t need a rear truss or bash plate because it’s going in a street truck or hot rod. We didn’t cheapen the actual housing, just removed some of the options.

Taking our CAD designed and laser cut housing into production starts with building the center section first. It’s based around using the Ford 9″ 3rd member and also fits the larger 10″ version used in off-road race trucks. We use high strength low carbon A50 steel plate which is considerably stronger than standard mild steel. The face plate is 3/8″ thick and MIG welded to 3/16″ sections that also have internal gussets for added strength. Once it’s fully welded, we then fixture it in our CNC mill and machine the faceplate for a precision flat sealing surface and also machine and tap the holes for the 3rd member studs. Other companies laser cut these holes and with the amount of welding taking place it distorts the bolt pattern so 3rd members do not fit correctly and have to be beat on with a mallet or drilled out. This is not the case with our housing since we machine them to 0.001″ tolerances after initial welding. We then use 3.50″ OD x thick .250w 4130 chromoly tubing and weld them into the center section. Using this size tubing is extremely strong and also offers various semi-float and full float hub combinations. All welding is done in specific fixtures to minimize distortion to insure that your housing is straight from start to finish.

Standard our housings are built both housing and pinion centered, but every housing we build is custom to your specs with many options available, call for more info and details. If you’re looking for a complete rear end, check out our online builder for options and pricing.

We recommend our 3.50 housings for lighter weight vehicles, hot rods and pre-runners running 33-37″ tires with lower horsepower engines.
