Item# S80

Redesigned and strengthened, our Super 80® transmission cases address weaknesses and add features that improve every aspect of the 4L80e. We build our Super 80® cases with full 360 degree internal case “lugs” that retain the center support and pressure plate. Not only are they lightweight and offer minimal drag, but their abuse tolerance has been kicked up several notches to handle high-horsepower levels without ending up with a ruined transmission.

Super 80®’s are massively tough, ductile, and leak-free with the strength to handle Turbo charged muscle cars, drag cars, rock crawling, and desert truck racing. Their modular, two-piece design allows them to be used with popular engines by simply changing bolt-on Superglide bellhousings. Our Super 80® transmission cases are SFI 4.1 certified* without requiring any external shields.
