ATS 303-901-2272 48RE RACING VALVE BODY FITS 2003-EARLY 2004 5.9L CUMMINS

Product Description

The ATS 303-901-2272 48RE Racing Valve Body is a performance-engineered upgrade designed for 2003–early 2004 Dodge Ram trucks equipped with the 5.9L Cummins diesel engine. Built specifically for high-performance and competition applications, this racing valve body delivers increased line pressure, faster shift response, and improved clutch holding power.

ATS modifies the factory valve body to eliminate common 48RE weaknesses by enhancing hydraulic control, reducing slippage, and optimizing shift timing. The result is firmer, more consistent shifts and improved transmission durability under high horsepower and torque conditions.

This racing valve body is ideal for trucks used in performance builds, sled pulling, drag racing, or heavy towing where maximum transmission efficiency and reliability are critical.
