CPP EXTREME-ER G56 TRANSMISSION WITH HD CASE FOR 2005-2018 DODGE RAM

Product Description

The CPP EXTREME-ER G56 TRANSMISSION WITH HD CASE is the ultimate manual transmission upgrade for 2005-2018 Dodge Ram 2500 and 3500 trucks equipped with the legendary G56 six-speed transmission. Built for serious towing, high-torque diesel applications, and long-term durability, the Extreme-ER combines upgraded transmission internals with a heavy-duty reinforced main case designed to reduce case flex and cracking under extreme loads.

Unlike standard replacement G56 transmissions, the Extreme-ER utilizes the same upgraded internal components found in CPP's Extreme Duty series while adding a heavy-duty HD case for maximum strength. The result is a transmission designed to handle demanding towing conditions, performance modifications, and commercial truck use with improved reliability and durability.
