This power steering pump repair kit is designed as an OE-style rebuild solution for Isuzu NRR and NPR-HD trucks equipped with 4HE1 4.8L or 4HK1 5.2L diesel engines (1998–2010) and equipped with hydro brake booster. Engineered to restore proper hydraulic pressure and steering performance, this kit includes precision-manufactured sealing components designed to address common wear issues such as fluid leaks, pressure loss, and steering noise. Ideal for rebuilding the original pump housing while maintaining factory steering response and reliability. Manufactured from high-grade rubber and sealing materials resistant to heat, hydraulic fluid exposure, and continuous-duty operation typical in commercial truck applications.
