Crossmember Information

We’re glad you asked! All of our Crossmembers are made in the USA. Our bolt to frame design means no cutting or welding, which makes installation easy! Plus, for most of our kits, installation hardware is included. Our products have been thoroughly tested and built to last. See all the reasons our customers choose G Force here.

We’re happy to! It’s easiest to explain by example. Let’s breakdown RCG-4L80K.

The first two letters always stand for Racing Crossmember.
Next is the Body Type(s). Options are A, B, C, E, F, G, X, Y, S-10, C10, and Mustang.
Body Type is followed by Generation.
The next letter indicates whether it is an Early or Late model.
Finally, the part number ends with the Transmission.

Here's another example: RCBE-400 = Racing Crossmember, B Body, Early model, TH400 transmission.

Remember, an individual Crossmember may fit multiple transmissions. The RCBE-400 also works with a TH350, TH200, TH250, Muncie, T10, Super T10, Powerglide, Saginaw, TH375, and 2004R. The product page for each Crossmember gives complete details and also includes a list of the vehicle models and years for which the Crossmember was engineered.

For easy reference we have created a list of Body Types by year, make, and model.

Yes, lightweight versions of our most popular Transmission Crossmembers have been on the market since early 2020. They were specially designed for performance enthusiasts. For example, racecar drivers are always looking for ways to reduce the curb weight of their cars. A lighter car means less braking time and faster acceleration on the track. Read "When Weight Matters—Try a G Force Lightweight Crossmember" for more details.

I know of customers' installation shops which have made modifications to our series of 3rd gen corvette Crossmembers to work with the 1982 model year, but the modification is often more than the average home installer is comfortable undertaking. The area which requires modifications are the horizontal mounting holes on our series of Crossmembers do not align with the holes on the vehicle frame. This typically requires some welding and properly positioned holes then drilled into the Crossmember. The vertical mounting holes do properly align, which helps in positioning and measuring to make the modifications.
