Specifications

For heavy-duty trucks that rely on M-100 steering gear, the 4058 Seal Kit is an essential maintenance or rebuild component. This comprehensive kit includes premium-grade seals, O-rings, gaskets, and wear components engineered to restore proper steering gear sealing and prevent fluid leaks. The seals are manufactured to withstand hydraulic pressure, temperature fluctuations, and continuous vibration — common in commercial trucking environments. With this kit, you can refresh your steering assembly to near-original spec, improving steering response, prolonging gearbox life, and minimizing downtime. Wofford Truck Parts offers 4058 as a reliable solution for fleet maintenance and steering system rebuilds.
