  • 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.

Quiet and easy to install on your car or SUV. Good quality blades.
Size: 24"/18"/14"
Wiper blades were easy to put on and come with an easy to follow instructional booklet. Wiper blades themselves are constructed well and made of quality rubber material. The other advantage is they come with all three blades which saves you time and money. Took about 10-15 minutes to replace all three wiper blades which can be done without any tools. The blades are quiet and so far do not cause any streaking. I recommend these blades if you’re looking for OEM quality blades that are easily replaceable and quieter than old blades that need replacing. They work well in heavy rainstorms.

Perfect fit at a perfect price!
Size: 26"/24"/14"
I was hesitant at first with buying an all-in-one set. In the past, I had to buy the windshield wipers separate from the rear due to compatibility issues. I read the reviews and took a chance. The material quality far exceeds what the price would suggest. The size matched the old blades. They look sturdy and will hold up over time. The instructions are mostly pictures but that proved to be enough. All you have to do is remove your old wiper blade. Identify the wiper arm end. Find that style on the installation sheet. Identify what clip configuration is needed for your wiper arm end from the same installation sheet. You may have to remove some layers of the new wiper blade assembly. It's easy to do since they are clipped on top of one another. For my 2021 Honda Pilot I had to remove the top two pieces to expose the type of clip I needed. It just snapped into place with minimal effort. Once both were installed I tested them by cycling wipes with wiper fluid. No streaks told me I had consistent contact throughout the wipe cycle. The back was simple. I had to rotate the old blade all the way around until the blade faced upward. Then I supported the wiper arm while I pulled the old blade out and away. The new blade is installed facing upward. As you rotated the blade downward, apply pressure towards the wiper arm and the blade will snap into place. I tested with a wiped cycle and the blade had constant contact with the glass. Crystal clear vision at the front and back. I will trust this brand with my other car, a 2017 Volvo XC60, and submit a review at that time. Order now! Operators are standing by!

High quality, great performance
Size: 28"/14"/14"
I was impressed by the quality of this product. It was a little tricky figuring out how to put them on at first, but once I did, it was actually very easy. This is a product that I will plan on purchasing again in the future!
