G Force Crossmembers RCG-400 Details

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
  • Bolts to the rear set of frame holes on drivers side frame rail

Application

Since different transmissions can share the same overall lengths as well as other measurements, they can also share some transmission crossmembers. G-Force has grouped the transmissions together that can share the same crossmember.

This Crossmember fits the GM-3 Transmission Group:

  • Turbo Hydra-Matic 2004R (TH2004R)
  • Turbo Hydra-Matic 400 (TH400)
  • Turbo Hydra-Matic 375 (TH375)

Fit great - a bit of loose weld slag trapped in the tubing but don't think it will hurt anything. Just can hear it rattling around a bit
