The Front Leaf Spring Bumper (Rubber Bump Stop) with OEM numbers 8-97039571-0 (also listed as 8970395710) is a verified OEM-grade direct replacement for the front suspension of ISUZU NPR, NKR, and ELF series trucks. This critical component is mounted on the chassis to limit suspension travel, preventing metal-to-metal contact between the axle and the frame during full compression. The rubber buffer absorbs impact energy, protects suspension components from damage, and ensures a smoother ride.
