The King Pin Set for Isuzu NPR, NPR-HD, NQR, and NRR Trucks is a critical front suspension component engineered to restore and maintain proper steering alignment and wheel pivot function. These king pins are precision manufactured to meet stringent OEM standards and provide smooth, reliable articulation between the steering knuckle and the axle beam.
Specifically designed for vehicles powered by Isuzu 4HK1-TCS and 4HK1-TCN 5.2L diesel engines, this king pin set delivers tight tolerances, superior strength, and optimized wear resistance. Worn or loose king pins can cause excessive play in the steering system, uneven tire wear, pulling, vibration, and compromised handling performance.
A correctly installed king pin set restores proper steering geometry, improves vehicle stability, and extends the life of related front suspension components. This set is ideal for maintenance, rebuilds, restoration projects, or correction of worn steering linkage in NPR, NPR-HD, NQR, and NRR truck platforms.
