Product Description
The CARDONE 27-7502 Remanufactured Steering Gear Box restores factory-original steering feel, control, and responsiveness for classic 4WD GM trucks and SUVs. The steering gear box is the core of the steering system, converting steering wheel rotation into precise directional movement at the wheels.
CARDONE thoroughly remanufactures each unit using 100% new O-rings and lip seals, eliminating the risk of leaks and extending the lifespan of the steering system. Shafts are resurfaced to exact OE tolerances to prevent early seal wear, and every gear is 100% hydraulically tested for correct pressure, flow, steering effort, and leak-free performance.
The rust-resistant Cool Dip coating penetrates deeply to protect all exposed metal surfaces with a uniform finish that will not peel or flake. As an OE remanufactured part, the 27-7502 guarantees proper fit, correct steering geometry, and long service life.
CARDONE’s environmentally friendly remanufacturing process reduces raw material use and energy consumption by up to 80%, delivering a sustainable, high-quality steering gear solution for vintage Chevrolet and GMC 4x4 platforms.
