Redesigned and strengthened, Reid Racing Super Hydra 400 transmission cases address weaknesses and add features that improve every aspect of the Turbo 400. They build their 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! A direct replacement for the GM case, Reid cases use an incredibly expensive permanent mold casting technique to increase the case wall thickness, making it sufficient to pass SFI 4.1 certifications without the need for any external shields or internal liners. Super Hydra 400s 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, 2-piece design allows them to be used with all popular engines by simply changing bolt-on Superglide bellhousings. Reid Racing Super Hydra 400 transmission cases are offered in drag/street and off-road versions, each with features geared specifically for those applications. Features: * Speedometer and governor provisions * Improved billet steel pressure plate * Oversized snap ring * Longer band anchor pins captured by oversize bosses * Additional dipstick hole on driver side * Multiple external pressure taps allow for monitoring of circuit pressures * Accept all style oil pumps, including 8-bolt and vari-pitch designs * Heli-coiled bellhousing and oil pump threads * Pre-machined to fit larger custom planetary gear carriers Off-road also includes: * Pre-machined side oil feed feature for 4L80-E center support * Front band anchor tapped for custom ARP anchor bolt (supplied) * Pre-machined bosses for input and output speed sensors * Un-machined speedometer boss for maximized 4x4 transfer case load support * Oil line ports machined for -AN fittings * Pre-machined with additional stud/nut clearance for Advance Adapters transfer case adapters * Available with a 4L80-E size pressure plate

ACT Mod-Twin 10.5 Heavy-Duty Race clutch kits tackle aggressive launches and rapid shifting of high-powered machines by combining twice the ceramic friction surfaces with a no-nonsense solid Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process to provide a light and consistent pedal feel. Puck-style friction plates with high-quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These friction plates uniformly transfer torque to a mono-drive chromoly hub, which is heat-treated for strength and durability, extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. The kits include a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, rigid mono-drive hub, floater, alignment tool and pilot bearing (where applicable). In addition, these Mod-Twin clutches by ACT are also fully rebuildable, and replacement discs may be ordered separately. Product features: * Recommended for Drag, Road or Rally Racing * Predictable, aggressive engagement, lightest pedal effort, quick shifting, possible start-off judder with mild to moderate transmission gear noise * Forged aluminum cover, mono-drive hub, exclusive diaphragm, and premium friction materials ensure this long-life twin performs and survives under the most demanding conditions * Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances * 100 percent clamp load tested, balanced, and SFI certified
