ultimate impact is more than noticeable while towing and daily driving. The additional horsepower and torque have helped keep massive loads moving, while the Banks Speed Brake has helped keep that same load under control when coming to a stop. The differential covers should extend pinion bearing life under the harsh towing conditions this truck will see every weekend, and the added height up front just plain looks better on this truck. In Part Four of this project build, the rear suspension will get some minor tweaks with OUO F-350 traction blocks and a set of short gusset traction bars to help prevent axle wrap under heavy load and acceleration.
Since the OUO covers use such a large fill port, they also include a custom machined key that can be inserted to tighten or remove the plug. Also note the magnetic drain plug used at the lowest point of the cover, which makes future fluid changes...
The rear differential cover on the 2008-2010 Ford Super Duty is small improvement over previous model years, with its aluminum construction and cooling fins, but the lack of a drain plug and the silicone needed to seal it makes servicing the...
Like the OUO front differential cover, the rear cover for the Ford 10.5 rear axle uses a thick 3/16” O-ring to seal the cover to the axle, making installation much easier and mess free with no more silicone to bead on and wait to dry. You can also...
This truck may have a lot of miles for its age, but the rear differential was still in perfect condition with no excessive play, no wear on the gears, and with some fresh gear oil and a new cover it should be good for quite a few more miles.
