Our heavy-duty replacement trans for 4-wheel drive pick-ups and Blazers is packed with additional upgrades to handle up to 450 horsepower and the additional strain of oversized tires and off-road use. This trans also includes our 4×4 torque converter with stall speed modified for off-road and towing use. This transmission features the factory “K” case with provision for bolt on aluminum dust cover and block supports and is designed as a direct replacement for GM four-wheel drive trucks originally equipped with a 700R4 transmission.
