Ford Mustang DTS Drivetrain And Suspension - Project ProCharged Pony - Back Half for Your Blower
If you're going to forge ahead with your elapsed times, you best have an anvil that can take the beating.
The billet tube ends are similar to the Ford 9-inch design and retain the axle without the use of C-clips. These ends are welded on and utilize a tapered roller bearing. DTS uses the tapered roller bearings because the bearing presses into itself when cornering. This is beneficial to bearing longevity, and it also prevents leaks.
Once the axle tubes have been straightened and welded, support trusses are welded/bolted on. These are optional and should be considered if clutch drops loom in your future, as they further prevent the axle tubes from twisting or flexing.
With the DTS billet ends installed, the housing is then painted before the differential is dropped in. For our application, DTS used an Eaton Posi unit, which has been modified to accept DTS' forged spider gears for use with 33-spline axles. Mark Williams built the 33-spline axles that employ pressed-on wheel bearings to be used with the billet ends.
The Pro 5.0 3.55:1 ring-and-pinion set had been in our 8.8 only a few months, so we opted to reuse it. We also had DTS install a TA Performance main support cover, which it can offer to you as well.
To constrain our new axle, we contacted UPR Products for a set of new control arms. After mentioning our car's horsepower level, UPR sales associate and racer extra-ordinaire Jeremy Martorella recommended the company's Pro Series arms, which use aluminum and spherical rod-end bushings. He also sent us a set of UPR's urethane-bushed chrome-moly control arms, should the Pro Series pieces become too noisy for our street machine.
In addition, we ordered a set of UPR's Max-Cross subframe connectors, as our Pony was long overdue for a set, especially since we don't intend to put a rollbar in the car just yet.
Not all 8.8s are created equal, and if you're as horsepower hungry as we are, consider getting a quality-built piece such as the one we received from DTS. It's the only way you'll be sure to get all the enjoyment your high-horsepower Mustang can provide.
