Redesigned and strengthened, our Super Hydra 400® transmission cases address weaknesses and add features that improve every aspect of the Turbo 400. We build our Super Hydra 400® 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 Hydra 400®’s are massively tough, ductile, and leak-free with the strength to handle rock crawling, as well as desert or short-course truck racing. Their modular, two-piece design allows them to be used with all popular engines by simply changing bolt-on Superglide bellhousings. Our Super Hydra 400® transmission cases are offered in drag/street and off-road versions, each with features geared specifically for those applications and are SFI 4.1 certified*.
