Engineered to outperform stock and aftermarket competitors, this comprehensive cooling package combines three precision die-cast components—Banks Cool Runner Oil Pan, Ram-Air Transmission Pan, and Ram-Air Differential Cover—to deliver unmatched thermal management, extending the life of your engine, transmission, and differential. Bundled for exceptional value, this system saves you up to $234 compared to individual purchases (MSRP: $1,425.56, Bundle Price: $1,190.85).

Key Features

• Banks Cool Runner Oil Pan: Features 19 deep-cut external radiator fins and 15 internal fins for superior heat dissipation. Its die-cast design ensures smoother oil flow, reducing cavitation and improving lubrication with an anti-cavitation dimple. Proprietary FlowThru Fins™ maximize thermal energy transfer, keeping oil at optimal viscosity to protect engine components.

• Banks Ram-Air Transmission Pan: Designed for the 10-speed Allison 10L1000, it includes 22 external and 20 internal fins, a forward-facing Ram-Air scoop for enhanced airflow, and 3 additional quarts of fluid capacity. The die-cast pan with integrated anti-slosh baffles and a 1/8" NPT port for a temperature sensor ensures cooler transmission fluid and reduced system stress. A replaceable plastic scoop protects the pan from damage.

• Banks Ram-Air Differential Cover: Patented design cools 5X better than competitors, rejecting heat faster with superior fluid dynamics. It uses less lubricant while extending gear life and fuel economy, outperforming stock and flat-back covers through optimized aerodynamics.

Why Choose Banks?

Unlike sand-cast competitors, Banks’ die-cast components offer denser, smoother surfaces with virtually no porosity, eliminating abrasive sand residue that can harm bearings and cylinder walls. The patented and patent-pending FlowThru Fins™ technology aligns internal and external fins for maximum heat rejection, ensuring your lubricants stay cool and effective under demanding conditions. No other system matches Banks’ engineering precision, rooted in decades of racing and military development.

Fitment Notes

For lifted trucks, ensure at least 10” of clearance between the OEM oil pan’s lowest point and the front cross member/drop bracket. Some lift kit drop brackets may need removal for Cool Runner Oil Pan installation. Refer to your lift kit guide for safe handling, as torsion bars are under load.

Benefits

• Extends engine, transmission, and differential life by maintaining optimal lubricant temperatures.

• Reduces oxidation breakdown, preserving fluid integrity.

• Saves money with fewer service intervals and a bundled price.

• CARB E.O. not required.
