The gearbox reduces steering effort, improves alignment stability, and helps extend the life of adjacent steering and suspension components. Whether replacing worn steering gear or upgrading an older system, 4037 offers dependable steering performance and reliability. Wofford Truck Parts supplies the M-100 pre-tested and ready for installation, providing fleets and owner-operators a trusted solution to maintain control and safety on the road.
