The UMI Performance 78-88 GM G-Body Transmission Crossmember (Part 3108-B) is a bolt-on steel structural support designed for classic G-Body platforms from 1978 to 1988. This component enhances the transmission mounting interface, providing the necessary rigidity for performance driving and drivetrain upgrades on vehicles like the Monte Carlo SS, Cutlass, Regal, and Grand Prix.
Constructed from heavy-gauge steel and finished with a durable black powder coat, the crossmember is ready for installation without any additional surface preparation. Its length of 48 inches is designed to fit within the G-Body frame rail structure, while its weight of 25.15 pounds reflects the robust material needed to support increased engine output and transmission loads.
This crossmember is particularly beneficial for enthusiasts who are upgrading their drivetrain or running modified engines. It supports various transmission types, including the factory 200R4 automatic and modern overdrive swaps like the 4L80E, making it a versatile choice for performance applications.
