Product Description
ISUZU CVR FVR King Pin Kit 1-87830039-0 KP-222 OEM Fit
The King Pin Kit with OEM number 1-87830039-0 and model KP-222 is a verified direct-fit replacement for ISUZU CVR / FVR heavy-duty trucks. This king pin kit is a critical steering knuckle component that connects the front axle to the steering knuckle, allowing the front wheels to pivot for steering while supporting the vehicle's weight.
Working Principle
The king pin kit serves as the pivot point for the steering knuckle on the front axle. It allows the knuckle to rotate for steering while maintaining precise alignment between the axle beam and the knuckle assembly. The king pin must withstand both vertical loads (vehicle weight) and horizontal loads (steering forces, braking forces, and road impacts).
The KP-222 kit includes a Φ50*252 mm hardened king pin, bronze bushings, thrust bearings, shims, seals, and mounting hardware. The king pin is manufactured from SAE1045 alloy steel for excellent wear resistance and fatigue strength.
Failure Symptoms
Replace the king pin kit when any of these symptoms appear:
- Steering wander or excessive steering play — worn king pin bushings allow the knuckle to move, causing the vehicle to wander on straight roads.
- Uneven or accelerated front tire wear — misaligned knuckle geometry from worn king pins causes cupping or scalloped tire wear patterns.
- Front end shimmy or vibration — loose king pins allow the front wheels to oscillate at certain speeds.
- Hard steering or binding — seized or corroded king pins prevent smooth steering operation.
- Clunking or knocking noise from the front axle — excessive clearance between the king pin and bushings causes metal-to-metal contact.
⚠️ Critical Inspection Note: ISUZU service manuals require that the king pin be replaced, never reused, when the knuckle is removed. Always replace king pins, bushings, bearings, and seals as a complete kit. Inspect the axle beam king pin bore for wear or elongation — if damaged, the axle beam must be replaced. After installation, a professional wheel alignment must be performed to restore correct steering geometry.

⚠️ Important Fitment Notes:
- This king pin kit is designed for the ISUZU CVR / FVR series. Confirm your specific model and year before ordering.
- The 1-87830039-0 is the primary OEM number. The 1-87830039-1 / 1878300391 is the updated version. The 1-87830-021-0, 1-87830-034-0, 1-87830-219-0, 1-87830-259-0, and 1-87830-737-0 are related numbers for the same application. Verify your exact OEM number against your original component.
- Always use new king pin bolts and nuts — never reuse old fasteners.
- After installation, a professional wheel alignment must be performed to restore correct steering geometry.
- For right-hand drive (RHD) vehicles, verify installation orientation. Refer to the ISUZU workshop manual for the correct procedure.
📌 Fitment Verification: To ensure 100% accurate matching, please provide the VIN or chassis number before ordering. We will verify it through the ISUZU global EPC system.
