Re-engineered for durability, the G Force RCG-700 Transmission Crossmember addresses common body bushing compression issues found in 1978-1988 G-Body vehicles. This robust crossmember ensures optimal performance and longevity for your drivetrain.
Installation is straightforward, though minor adjustments may be needed. In cases where floor pan clearance is tight, gently lifting the pan with a wood block and floor jack can provide the necessary space. The passenger side hump is designed taller for the specific G-Body configuration.
Installation note: On some 78-88 G-Body models, it may be necessary to remove the catalytic converter heat shield from the passenger side floor pan to ensure proper fitment and exhaust clearance.
This crossmember is engineered to be compatible with a range of transmissions, including the 700R4, 4L60, 4L60E, TKO-500, and TKO-600, offering a versatile solution for your G-Body’s transmission needs.
