Rear Leaf Spring Sub-Spring Bumper 8-94119958-0 8941199580

OEM Rubber Stop Buffer With Mounting Bolt for ISUZU NKR/NPR/NQR 4BD1 4JB1

Product Overview

The Rear Leaf Spring Bumper (Rubber Buffer Stop) with OEM numbers 8-94119958-0 and 8941199580 is a verified OEM-grade direct replacement for a wide range of ISUZU light and medium-duty trucks. This critical suspension component prevents metal-to-metal contact between the axle and chassis during full compression, absorbing impact energy and protecting suspension components.

  • OEM Specification - Verified by ISUZU OEM part numbers 8-94119958-0, 8941199580 with cross-references 8972543870, 8983350390, 8941199581
  • Proven Durability - High-quality rubber with integrated metal mounting bolt engineered for commercial truck operation
  • Broad Compatibility - Fits ISUZU NKR, NPR, NQR, NRR, NPR-HD models from 1986 to 2024 with 4BD1, 4JB1, 4JH1, 4HK1 engines
  • Verified Fitment - Confirmed for NPR66 (1991-2003), NPR71 (1998-2002), NKR77 (2002-2005), NPS59 (1992-1994) and many others
Failure Symptoms
  • Harsh Bottoming-Out: Loud thud or metal-on-metal impact when driving over bumps
  • Visible Cracking or Deterioration: Cracks, splits, or missing chunks from rubber buffer
  • Sagging or Uneven Ride Height: Rear suspension sits lower than normal
  • Reduced Load-Carrying Capacity: Excessive suspension compression under heavy loads
  • Increased Suspension Noise: Rattling or clunking sounds from rear axle area

Warning: A worn or missing leaf spring bumper can lead to serious suspension and chassis damage over time. Prompt replacement is strongly recommended.
