Leaf Spring Assembly A167 for ISUZU NKR NPR NQR 4JB1 4HF1 — Verified OEM Fit Front/Rear Suspension Leaf Spring Pack with Bushings

The Leaf Spring Assembly with reference code A167 is a verified direct-fit replacement for ISUZU NKR / NPR / NQR / ELF light and medium-duty trucks equipped with 4JB1 / 4JB1-T / 4HF1 / 4HG1 / 4HK1 diesel engines. This leaf spring is a critical component of the vehicle's suspension system, responsible for supporting the vehicle's load, absorbing road shock, and maintaining proper suspension geometry under all load conditions.

Working Principle

The leaf spring is a load-bearing suspension component composed of multiple spring steel leaves stacked and clamped together. It connects the axle housing to the vehicle chassis frame, supporting the vehicle's weight while allowing controlled vertical movement of the axle over uneven terrain. The leaf spring absorbs road shocks through the elastic deformation of its spring steel leaves, converting impact energy into controlled flex rather than transmitting it directly to the chassis and cargo.

The A167 assembly features a multi-leaf configuration with a main leaf and additional secondary and overload leaves, all secured by a center bolt and rebound clips. The spring eyes at both ends are fitted with rubber bushings to isolate vibration and ensure smooth articulation at the chassis mounting points.

This leaf spring is manufactured by YIMI (Guangzhou) Automotive Parts Co., Ltd, a leading Chinese supplier of ISUZU truck parts, and is branded under the Zhengzhong (正众) name. The NKR marking on the spring surface confirms its application for the ISUZU NKR platform.

Failure Symptoms

Replace the leaf spring assembly when any of these symptoms appear:

  • Visible cracks or broken leaves — a cracked or broken spring leaf compromises load-carrying capacity and can cause sudden suspension collapse.
  • Sagging suspension — the vehicle sits lower than normal on one or both sides, indicating spring fatigue or leaf failure.
  • Excessive bouncing or bottoming out — weakened springs fail to absorb road shocks, causing the suspension to bottom out under load.
  • Uneven tire wear — misaligned suspension geometry from a worn spring causes irregular tire wear patterns.
  • Clunking or knocking noise from the suspension — loose or worn leaf spring bushings or center bolt allow the spring pack to shift, producing noise.
  • Vehicle pulling to one side — a weakened spring on one side causes asymmetric suspension height, leading to steering pull.
⚠️ Critical Inspection Note: ISUZU service manuals require that when the leaf spring assembly is removed or replaced, all U-bolts, spring bushings, and shackle pins must be inspected for wear and replaced if any abnormality is found. U-bolts must always be replaced, never reused. Always tighten U-bolt nuts in a diagonal sequence and re-torque after the first 100 km of driving. Note: The factory service manual for the N-Series includes a leaf spring legend noting that when replacing the leaf spring assembly, use the leaf spring with the same camber as the original.

  • Always replace U-bolts with new units — never reuse old U-bolts.
  • U-bolt nuts must be tightened to specification in a diagonal sequence. Re-torque after the first 100 km.
  • Note: The factory service manual for the N-Series includes a leaf spring legend noting that when replacing the leaf spring assembly, use the leaf spring with the same camber as the original.
  • For right-hand drive (RHD) vehicles, verify clearance and mounting orientation. Refer to the ISUZU workshop manual for the correct procedure.
