Make Your Transmission Swap Easy With Crossmembers
The rise in popularity of swapping transmissions has created an increased need for transmission conversion kits and parts. A transmission swap is switching the OEM (original equipment manufacturer) transmission to a new one. Transmission swaps are common because they give the option for an upgraded transmission that wasn’t available when you first bought/owned your vehicle.
Transmission swaps will improve your fuel efficiency, eliminate recognized OEM vulnerabilities, and handle heavy load situations better. Crossmembers are an essential tool of the transmission swap process and adapter kits. A manufacturer that specializes in the design of automotive accessories will provide you with the most innovative crossmembers for your transmission swap.

What Are Crossmembers?
To make transmission swaps easier, specific kits and parts are necessary for a smooth transition. A crossmember is a steel-reinforced bar that bolts across the underside of your vehicle to support the transmission. Crossmembers have to be strong enough to resist deflecting and twisting. Strength, durability, and size are critical components for proper handling and body panel alignment.
You want to find a crossmember manufacturer that guarantees each engineered crossmember will fit just like a factory transmission crossmember. With custom-fit crossmembers, there’s no need to change the mounting location. A transmission swap should be all about ease and efficiency. Every crossmember variation is designed for specific makes and models of cars to be the exact fit.
Why Does Weight Matter?
For any car guru or even race car driver, they understand the importance of weight in their vehicle. Weight or changes in weight affects every alteration of their vehicle. Many drivers are conscious of their lowering curb weight, also know as the total weight of the car without the driver in it. Lightweight crossmembers are important aftermarket options to keep your curb weight low.
Any type of change in the weight of your vehicle will affect its performance. A carefully thought-out and balanced curb weight gives you better handling, faster braking, and better rapid acceleration. Less weight will reduce your emissions and fuel consumption because your vehicle won’t have to work as hard.
What Crossmember Is Best For Your Vehicle?
With so many different makes, models, and years of vehicles, it’s important to pick the correct crossmembers for your vehicle. Read below about the years and models that correlate to each crossmember.

G-Body 700R4 RCG-350 Crossmember
If you have a Malibu, Monte Carlo, El Camino, Cutlass, Grand Prix, or Regal model vehicle made between 1978 and 1988, a G-body crossmember RCG-350 is the best selection. It will fit TH350, Muncie, Powerglide, T-10, Super T-10, Saginaw, and TH200 transmissions.
