SUPER DUTY

The OUO front and rear covers use a machined surface with a groove that accepts a thick 3/16” O-ring to make installation cleaner and easier than the factory silicone-style seal. They also incorporate a magnetic drain plug at the lowest point of the cover to ease future fluid services. But one of the most impressive design features of the cover is the massive 1-7/8” fill port cast and machined into it. This large port makes filling the cover much easier, while allowing you to actually see inside the differential to check the fluid level.

OUO LEVELERS

While the added weight of the new TDK front bumper didn’t cause the front suspension to sag much, plans for raising the rear of this F-250 truck to F-350 height with taller OUO Traction Bar lift blocks when the OUO Traction Bar kit gets installed (stay tuned for Part Four of the project), something needed to be installed to add some front-end tire clearance. The Adjustable Coil Levelers from OUO seemed the perfect solution, as their unique threaded post design allows complete height adjustability by raising or lowering the lower coil spring perch to your desired level. The real beauty behind this style of leveling system is the fact that it will have no effect on ride quality since you’re doing nothing to chance the coil spring compression rate, but can change the front suspension height anywhere up to 2.5 inches over stock.

The kit installs in around two hours and you’ll be able to fine-tune the stance and rake of the truck to fit your personal preference. With just a 33-inch tire and stock wheels under the truck and the factory F-250 block still out back, the front end was brought up 1.5 inches for now. But as the rear suspension is upgraded and raised up another two inches, a set of taller 35-inch tires may be considered, so this ACL system may get adjusted to the full 2.5-inch height to improve looks and tire clearance, but that’ll be revisited if and when the time comes. And while it doesn’t pertain to this build, for those already running big aftermarket lifts under their Super Duty with taller coil springs, the OUO Adjustable Levelers could still be added to get you another inch or two, or simply to fine tune your final lift height front to back or even side to side.

While the cosmetic and performance changes to this 6.4L Power Stroke haven’t been very drastic, their

Since the used truck was purchased a little high on mileage and had been used for towing, the owner opted to service the front and rear differentials to be sure the fluid was fresh. This meant it was the perfect time to upgrade to the cast aluminum...

The OUO front cover for the Dana 60 under the Ford Super Duty trucks is one of the only high-flow covers available that will clear the factory steering linkage, like tie-rod, track bar, and track bar bracket. They also use a 3/16” O-ring for sealing,...

OUO didn’t just make a nice-looking, easy-to-service differential cover; the team spoke with Dana Spicer, manufacturer of the Ford Super Duty front axle, to ensure they engineered a cover that would improve oil flow to the bearings. Additional volume...

The supplied line management tab is set onto the axle, then the adjustable leveler system can be installed using the supplied bolt. Be sure to use some Loctite on that center bolt and torque to 140 ft-lb.

With the OUO Level installed, the factory coil spring can be reinstalled, along with all the other pieces you unbolted. Raise the axle back up into place, reattach the ABS lines, brake line brackets, lower shock bolts, and sway bar end links.
