Ultimate Fluid Cooling Bundle for 2020-2024 Chevy/GMC 6.6L Duramax

Engineered to cool motor Oil

The Banks CoolRunner Oil Pan for the 2020-2024 Duramax out-performs and out-cools the competition by leveraging decades of racing and military engine development.

•19 deep-cut huge external radiator fins provide more surface area to the cool air moving under the truck.

•Die-cast process provides a smoother interior surface which improves oil flow to the pickup tube and drain.

•A smooth, streamlined area around the oil pickup with an engineered anti-cavitation dimple improves oil flow to the pump by reducing restriction at the filter inlet.

•15 internal fins absorb more heat from the oil than a stock or any other aftermarket pan.

Banks proprietary FlowThru Fins^TM maximize thermal energy transfer by lining up the internal and external features with each other.

Engine heat is efficiently drawn from the sump where the hottest oil rests. Cooler oil retains the proper viscosity, which means metal-on-metal surfaces remain properly lubricated.

Engineered to run cool

The Banks Ram Air Transmission Pan for 2020-2024 Duramax trucks with the 10-speed 10L10000 transmission outperforms and outcools the competition by leveraging decades of Ram-Air technology and thermal management expertise honed in racing and military engine development.

Taking advantage of the fast-moving cool air under your truck, the Ram-Air Transmission Pan draws ambient air through the large forward-facing scoop, funneling it through the external heat radiation fins.

The plastic scoop is also designed to break away without causing damage to your pan, just in case. If this happens to you, let us know and we will send a replacement Ram-Air scoop on the house.

•1/8" NPT port for easily adding a supplemental temperature sensor to your vehicle.

•22 deep-cut external radiator fins provide more exposed surface area to the cool air moving under the truck.

•Integrated support structure for internal filter acts as anti-slosh baffles for fluid in the pan.

•20 internal fins absorb more heat from the oil than a standard pan or all other aftermarket pans.

•Die-cast process provides a smoother, less porous interior surface and improves fluid flow in the pan.

The Banks proprietary FlowThru Fins^TM maximize thermal energy transfer by lining up the internal absorption and external radiator elements with each other.

Transmission fluid heat is efficiently drawn from the fluid, reducing stress on your Duramax's cooling and lubrication systems.

Die-Cast vs Sandcast

All Banks lubrication cooling products are die-cast, not sand-cast like competitors. Made with far greater precision, a die-cast part is denser, smoother, and has virtually no porosity compared to the equivalent sand-cast part.

Sand-cast parts can even retain the sand they were molded with. (You don’t want sand in your oil). Finally, our long, thin cooling fins are only possible with a die-cast process. Although this process costs more, we think it's worth it.

Purpose Built

The Banks Engineering team’s goal was to perfect fluid flow and reject BTUs from the fluid as fast as the ring and pinion puts them in. If the fluid flow is impeded in any way, it results in resistance and aeration which reduce fuel economy and creates heat, thereby degrading the fluid and decreasing the lifespan of the gearset.

Outperform The Competition, For Less

Thanks to its superior fluid and aerodynamics, the Ram-Air® Cover out-performs stock and flat-back high-capacity covers and does so with less lubricant. Increased distance between service intervals and less lubricant means you'll save money while extending gear life.
