Why should I choose a G Force Crossmember?

Would you decode your Crossmember part numbers?

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.

Do I have a comprehensive list of which Crossmembers work with different transmissions?

We do. Check out our Crossmember Transmission Groups page to find the group in which your transmission falls. You can use the group number as a cross-reference to find out which crossmembers support which transmissions. Find out all the details in our guide, "How to Find the Right Crossmember to Support Your Transmission."

If I buy your Crossmember and decide to swap out my transmission later, will the same crossmember work?

Yes, as long as both transmissions are in the same transmission group. Check out "How to find the right Crossmember to support your transmission" for more information. Although this page is designed to help our customers order the correct Crossmember, you'll find everything you need to know about transmission groups there as well. Our Make, Model, Year search bar is also a valuable tool for finding the correct Crossmember quickly. You'll find it at the top of our home and products pages.

Do you carry lightweight crossmembers?

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.

What is the difference in weight between a regular and lightweight Crossmember?

The exact amount varies depending on the Crossmember. Here is a list for the Crossmembers currently in our product line: SKU Weight Difference RCG-350 5 lbs RCG-400 7 lbs RCG-700 6 lbs RCAE 10 lbs
