SHOPTALK

See the G Force Crossmember Overview for more info.

The RCG-400 is bolted to the rear set of frame holes on the driver’s side frame rail.

On some installations it is necessary to remove the catalytic converter heat shield from the passenger side floor pan.

For all 78-88 G body crossmembers the passenger side hump is the taller of the two.

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 instances where there is slight interference they have been able to gently lift the floor pan with the assistance of a floor jack and a wood cushion to create enough clearance for installation.

This crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom.
