The SunCoast 48-TCS Transfer Case Support is designed to eliminate one of the most common failure points on 48RE-equipped Dodge Cummins trucks. The factory 48RE overdrive housing supports the weight of the transfer case with minimal reinforcement, which can lead to cracked tail housings, fluid leaks, and transmission damage under towing and high-performance conditions.

This heavy-duty support system adds critical reinforcement between the transfer case and factory skid plate to reduce stress, flexing, and torsional movement. Whether your truck is used for towing, hauling, daily driving, or high-horsepower performance applications, the SunCoast Transfer Case Support helps improve durability and long-term transmission reliability.

Features

• Helps prevent cracking of the 48RE overdrive tail housing
• Reduces torsional flex and transmission case stress
• Helps eliminate common tail housing fluid leaks
• Heavy-duty steel bracket construction
• Uses a universal GM-style transmission mount
• Bolt-on installation with included hardware
• Installs using factory skid plate mounting points
• Designed for towing, hauling, and high-horsepower applications

Why Install a Transfer Case Support?

The transfer case on 48RE-equipped 4WD trucks places significant stress on the overdrive housing. Over time, constant twisting and drivetrain movement can cause cracked housings and recurring fluid leaks. The SunCoast 48-TCS adds additional support to help stabilize the transfer case and reduce strain on the transmission housing.
