SUPER HYDRA TH400 TRANS CASE SFI 4.1 SUITS DRAG & STREET

Description

The Turbo 400 is the favored 3-speed transmission today for high horsepower applications because of its light weight, minimal drag, and its tolerance of abuse. As rugged as it is, there is one glaring weakness; the internal case “lugs”that retain the center supportand pressure plate do not go completely around the inside of the case. At high horsepower levels, the “lugs” closest to the gap become overloaded and they fail. This sets off a chain reaction and all of the remaining “lugs” fail in a zipper-like fashion ending up in a ruined transmission. Reid Racing, Inc. has redesigned the Turbo 400 to correct this problem and has added dozens of features that improve every aspect of the case.
Justas with the renowned Superglide cases, Reid Racing uses a phenomenally expensive permanent mold casting technique for the Super Hydra 400, which results in a massively strong, tough, ductile, and leak-free case that is 100% interchangeable with existing GM Turbo 400 cases. Standard governor, speedometer, and wire connector feedthrough is featured in the case. By using the same bellhousings asthe Reid Racing Superglide, the two-piece design allows the Hydra 400 to be used behind all popular engines by simply changing bolt-on bellhousings.
The case wall thickness is sufficient to pass SFI 4.1 explosion requirements without any external shields or internal liners. This increased wall thickness also provides the strength required for off-roadapplications such as rock crawling and desert or short course truck racing.
Twoseparate cases are offered: a Drag/Street version and an Offroad version, each with features geared specially for its application. Included in both versions is a new billet steel pressure plate and an oversize retaining snap ring. The Super Hydra 400 ensures that Turbo 400 style transmissions can withstand huge horsepower levels and itsuse will not be limited by thenumber of remaining junkyard cores.
Standard bellhousing flange fits Reid Racing’s full line of SFI 30.1bellhousings, as well as SFI 6.x “cans” from Browell, Trick Titanium, Quicktime, and others. Indexing ring on the oversizedflange properly centers bellhousing.
