Transmission Crossmember 88-98 GM P/U w/Mount

The G Force Transmission Crossmember 88-98 GM P/U with Mount (RCC10-4PRO) is a bolt-on steel crossmember engineered for GM LS-Series engine swaps in 1988–1998 full-size pickup trucks running 2WD configurations. This component bridges the gap between modern LS powerplant integration and older GM truck platforms, providing a secure structural mount for transmission and driveline components during high-torque engine swaps.

Constructed from heavy-duty steel and finished in black powder coat, this transmission crossmember weighs 25 lbs and measures 12 x 6 x 56 inches, delivering the structural rigidity necessary to support LS engines that produce significantly more torque than stock drivetrain components were designed to handle. The bolt-on design eliminates welding, making installation straightforward for builders who prioritize reversibility and shop access. The integrated mount point ensures proper transmission alignment, critical for NV4500, NV5600, 4L80E, and other popular swap transmissions paired with LS engines in truck applications.

This crossmember is purpose-built for 2WD C/K trucks of the 1988–1998 generation undergoing LS conversion. Truck builders and engine swap enthusiasts rely on this component to maintain proper driveline geometry, reduce vibration, and eliminate structural flex that compromises transmission longevity. The RCC10-4PRO specification ensures compatibility with the full range of 2WD truck frames in this era, whether the swap targets a 5.3L, 6.0L, or larger displacement LS variant.
