G Force RCG-6L80 Transmission Crossmember, 84-88 G-Body, GM-6

Sku # 64084886

Mfr. Part # RCG-6L80

This generation of vehicle is prone to body bushing compression, even with some southern vehicles. If the floor pan is too close to allow installation, it may be necessary to replace the body bushings. Some customers have reported that with slight interference instances, they have been able to gently lift the floor pan with the assist of a floor jack and a wood cushion, thus providing the required clearance for installation. On all 78-88 G body crossmembers, the passenger side hump is the taller of the two, and on some installations, it is necessary to remove the catalytic converter heat shield from the passenger side floor pan.

• Fits 1984-1988 G-Body
• Crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom

• The primary frame change on this generation of vehicles is beginning with 1984 models and the implementation of the 2004R transmission which required positioning the crossmember further to the rear of the vehicle. This is evidenced by 2 sets of frame holes for the crossmember on the driver side of the vehicle. G force has developed the frame extension (FE-100) to duplicate this longer frame on the early generation vehicles.
