The Aerodynamic Drive Cover + Wheel from Alcoa Wheel Products is an exclusive cover plus wheel system designed for the 22.5” diameter by 8.25” width and 22.5” diameter by 14” width wheels, Nos. ULA18x, 84U61x, and 84U64x. The cover’s design powers fuel efficiency while weighing less than comparable solutions, the company said. Its design features a unique approach in attachment style. The cover provides a measurement-free installation process. It is also affixed to a ring which is secured in the flange groove of the wheel (patent-pending flange design), leaving the hub unburdened by heavy brackets and ensuring appropriate mounting consistency for maximum results. Additionally, the cover features a 9” inspection opening, which allows for a clear view of all wheel-end components, eliminating the need for wheel cover removal during pre-trip, post-trip, road-side inspections, and tire inflation. According to the company, the system saves up to 0.96 gallons of fuel per 1,000 miles.
