’78-88 El Camino, Malibu and Monte Carlo

Our transmission crossmembers are precisely manufactured in the USA using only top-quality materials. These are available for a variety of transmission applications since the crossmembers utilize 2” x 2” mild steel tubing, 1/2” plate for dual exhaust humps, 3/16” plate for end mounts as well as Grade 8 hardware. Each crossmember is painted a gray Hammertone color and also features detailed instructions for a painless installation.

Notes

  • L240378, L240380 and L240381 require the use of frame extensions (part# L240383 sold separately) for proper mounting on 1978-83 cars.
