- 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.

Not completely indestructible but definitely long-lasting with plastic bits everywhere
Color: 1PC-Beef-Red
It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.

Great Product!!!
Color: 1PC-Beef-Red
This is the first toy my dog has not demolished. I need to buy more just like it just in case something happens to this one. It's worth every bit of the money I spent on it.
