  • Fits Models: GM RWD G-Body; Malibu, Monte Carlo, El Camino, Cutlass, Grand Prix, Regal, Century, LeMans, Caballero, Bonneville
  • Fits Years: 78-83
  • Fits Transmissions: TH400, 2004R
  • If you are looking for improved performance check out our lighter weight, next generation of this crossmember,  RCGNG-400KBLK.
  • We recommend a polyurethane transmission mount. The G Force  GMTM is sold separately.
  • G force has developed a frame extension, GF-FE100, to duplicate this longer frame on the early generation vehicles. The RCG-400K is pre-packaged with the frame extension.
  • The primary frame change on the 1978-1988 generation of GM G-Body vehicles begins 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 two sets of frame holes for the crossmember on the driver side of the vehicle.
  • Note: Some 1983 Hurst Olds are known to have the 2004R transmission and thus the longer frame rail which does not require the GF-FE100 frame extension that is included in this Kit.  Some 1984 El Caminos retained the early frames and do require an GF-FE100 frame extension to run this crossmember.

It’s just an air filter

It’s exactly how it’s pictured. Not sure what else to say it’s an air filter. I guess it’s doing its job

Only 98% efficient. Says 99.9 in the ad. There is a huge difference between those two efficiencies.
