1985-2019 Powerstroke Ram Air Black Ops Differential Cover (19258)

Fits

The Banks Ram-Air Differential Cover is a game-changer in the cover industry. They took the extra mile when designing the 19280 Ram Air Cover by testing all the flat-back covers on the market to determine where they were falling short and how Banks could improve the design. This is what they came up with, the new Ram Air Differential Cover cools 5 Times Better than flat-backs.

In-fact, they found that other flat-back differential covers didn't cool as well as advertised and suffer from poor fluid dynamics and as a result actually reduce your fuel economy and efficiency.

Purpose Built

When the team at Banks sat down at the drawing board, the goal was to perfect fluid flow and reject BTU's from the fluid as fast as the ring and pinion put them in. When you slow down the fluid in any way, it results in resistance and aeration which KILL your fuel economy. Not only does it hurt your fuel economy, it begins to build heat, this heat will slowly but consistently degrade the fluid and decrease the lifespan of the gearset. 

The Banks Power design is to allow the fluid to flow through your gears with little to no resistance, keeping your oil cool and having consistent coverage on your gears without drowning the bearings.

Currently, most aftermarket covers floating around the market today have fins for cooling. However, those fins really don't do anything, yes, they may dissipate heat to some extent, but there really is no airflow hitting the back of your cover. Also, most of the flat back covers impede the flow, imagine firing a hose at a brick wall, what happens to the fluid?

The Banks Power Ram-Air system increases the amount of airflow that gets pushed passed your differential by scooping air as you move and directing it through the fins on your cover.

 

 

Other covers may use fins to cool the differential but they don't have a method of pulling the airflow into those fins on the differential.
