TH400 - SUPER PUMP - LOCK-UP - OEM SHAFT - ADJUSTABLE PRESSURE REGULATOR

TH400 Super Pumps

ATI's Turbo 400 Super Pump is designed to prevent tube damage and increase fluid flow for better cooling. Starting with a new permanent-mold Aluminum casting, the finished pump features a 3 piece design with a bolt-in, one-piece, heat treated alloy steel stator tube for improved fluid routing over the pressed in OEM or aftermarket tubes. Micro-finished coated gears and ATl's exclusive hardened steel wear plates are standard equipment. At just 12 Ibs, the ATI pump is 5 lbs less than an OEM unit. The OEM fluid passages and depths were retained as well as the pressure regulator. An adjustable pressure regulator is also available.

The gear side comes with 8 bolt holes and is designed to mate with ATI built 8-bolt stator halves, and all OEM rear castings except ones stamped "649". If using as an 8 bolt pump in a 6 or 7 bolt case add helicoils in the stator half and run a shorter bolt.

Options for OEM sized 27 spline and 29 spline input shafts, larger sizes available for high HP use.
