Rear Shock Absorber Assembly 0503010002 05030-10002 for ISUZU NJ140 CYZ CXZ EXZ — Verified OEM Fit Rear Suspension Shock Absorber with Bushings

Product Overview

The Rear Shock Absorber Assembly with OEM number 0503010002 is a verified direct-fit replacement for ISUZU NJ140 / CYZ / CXZ / EXZ medium and heavy-duty trucks. This shock absorber is a critical component of the rear suspension system, responsible for controlling spring oscillation, dampening road-induced vibrations, and maintaining tire contact with the road surface for safe vehicle handling and braking.

Working Principle

The rear shock absorber is a hydraulic damping device that converts the kinetic energy of suspension movement into thermal energy, which is then dissipated into the surrounding air. It is mounted between the vehicle's chassis frame and the rear axle, working in parallel with the leaf spring suspension.

When the vehicle encounters bumps, potholes, or uneven road surfaces, the rear shock absorbers compress and release hydraulic fluid under pressure, absorbing the energy from the impact. This action helps to minimize excessive bouncing or oscillation of the suspension, ensuring that the tires maintain consistent contact with the road for improved traction and handling.

The 0503010002 shock absorber features a twin-tube hydraulic design with a piston valve that controls oil flow between the inner and outer tubes during compression and rebound strokes. The chrome-plated piston rod ensures smooth operation and long seal life, while the nitrile rubber bushings at both mounting eyes isolate vibration and reduce noise transfer to the chassis.

Failure Symptoms

Replace the rear shock absorber when any of these symptoms appear:

  • Excessive bouncing or oscillation after hitting bumps — a worn shock absorber cannot control spring rebound, causing the vehicle to bounce excessively.
  • Nose dive during braking or body roll during cornering — weakened damping allows excessive weight transfer, reducing stability.
  • Uneven or accelerated tire wear — loss of tire contact with the road causes cupping or flat-spotting.
  • Visible oil leakage from the shock absorber body — a leaking seal allows hydraulic oil to escape, reducing damping effectiveness.
  • Knocking or clunking noise from the rear suspension — worn bushings or a loose shock absorber mount produce noise over bumps.
  • Vehicle sagging at the rear — a completely failed shock absorber can contribute to rear suspension sag.
⚠️ Critical Inspection Note: ISUZU service manuals require that shock absorbers be inspected for oil leakage, bushing wear, and mount security at every suspension service interval. Always replace shock absorbers in pairs (left and right) to maintain balanced damping performance. Torque the shock absorber mounting bolts to specification — verify against your specific ISUZU workshop manual. After installation, check wheel alignment to ensure proper steering geometry.

⚠️ Important Fitment Notes:
  • This shock absorber is designed for the rear axle application. The front axle uses a different part number (0503010001).
  • Confirm the mounting type (eye-to-eye or eye-to-stem), extended/collapsed lengths, and bushing sizes against your original component before ordering.
  • Always replace shock absorbers in pairs (left and right) to maintain balanced damping performance.
  • Torque the shock absorber mounting bolts to specification — verify against your ISUZU workshop manual.
  • After installation, check wheel alignment to ensure proper steering geometry.
  • For right-hand drive (RHD) vehicles, verify clearance and routing. Refer to the ISUZU workshop manual for the correct procedure.
