Next Gen G-Body Crossmember for TH400

Are you looking to enhance the performance and quality of your 1978-1983 Next Gen G-Body vehicle? Look no further! Our Next Gen G-Body Crossmember, designed specifically for TH400 and 2004R transmissions, is the perfect solution for your classic ride. This crossmember is meticulously crafted by G Force Performance, ensuring a lighter weight design that not only improves performance but also maintains the same high-quality standards as the original RCG-400K crossmember. With its durable construction and precise engineering, this crossmember is a must-have for any G-Body enthusiast.

Fitment and Compatibility

Our Next Gen G-Body Crossmember is designed to fit a wide range of models, including Malibu, Monte Carlo, El Camino, Cutlass, Grand Prix, Regal, Century, LeMans, Caballero, and Bonneville. Whether you have a Pontiac, Chevrolet, Buick, or Oldsmobile, this crossmember is compatible with your vehicle. The fitment years span from 1978 to 1983, making it an ideal upgrade for classic cars and trucks. Along with the crossmember, we offer a frame extension, FE-100, to extend the frame for early generation vehicles, ensuring a seamless installation and improved fit.

Enhanced Performance and Quality

In addition to the frame extension, we recommend using a polyurethane transmission mount, GMTM, for optimal performance and durability. This mount is sold separately, but it is an essential component for the complete upgrade. The RCG-400KNG-BLK crossmember is pre-packaged with the frame extension, making it easier for you to install and enjoy the benefits of this high-quality product. With G Force Performance's commitment to excellence, you can trust that this crossmember will provide the performance and reliability you expect from your classic G-Body vehicle.
