Product Description

Swapping transmissions or upgrading a G-body's driveline usually means fighting the factory crossmember's fixed mounting position - it simply wasn't built with adjustability in mind. The UMI 3108-B solves that with a modular, laser-cut tab-and-slot design that offers multiple mounting locations, letting you dial in the correct driveline angle for whatever transmission you're running rather than working around a one-size-fits-all bracket.

Built from rectangular tubing and mild steel mounting plates and finished in black powder coat, it supports everything from a TH350 to a 700R4 or Powerglide, with generous cutouts that leave room for larger dual exhaust systems. Since the transmission mount itself is sold separately, pick the bushing option that matches your transmission before ordering.
