Front Right Door Assembly 8978523771 / 8-97852377-1 For ISUZU NKR55 4JB1 — Bare Shell, Without Trim, Ready For Paint, RH Passenger Side

The Front Right Door Assembly with OEM references 8978523771 / 8-97852377-1 (factory number 8-97852377-PT) is a verified replacement body panel for the ISUZU NKR55 light truck equipped with the 4JB1 engine. This is the complete front right-hand (RH / passenger side) door shell, supplied bare — without interior trim, glass, regulator, latch, or hardware — and ready for paint.

The unit is confirmed by multiple independent listings as "DOOR ASM FRT WO/TRIM RH". The "WO/TRIM" designation confirms the supply scope is a bare shell without interior trim. It is a high-strength steel door shell designed to provide side-impact protection and structural integrity. The door is supplied in original steel colour and can be painted to match the vehicle's factory finish upon request.

This is the front right door shell. The left-hand counterpart uses 8-97852378-1 / 8978638480. Left and right shells have mirror-image hinge positions, latch orientations, and mirror-hole layouts. They are not interchangeable.

This listing covers the door shell only. Interior trim panel, glass, window regulator, latch, hinges, and mirror hardware are not included. The unit is confirmed as "WO/TRIM" (without trim). If a complete door assembly with trim is required, that is a different product scope and must be specified separately.

The shell is supplied unpainted (original steel colour). The body shop must prepare and paint the surface to match the vehicle's finish. The supplier offers a painting option to customer requirements.

• Collision damage: Impact to the front right door — dents, creases, or structural deformation that cannot be economically repaired.
• Rusted or perforated door skin: Corrosion along the lower edge, seams, or window frame that has progressed beyond surface rust.
• Broken hinges or hinge mounting points: A door that sags, binds, or will not close flush due to damaged hinge reinforcement within the shell.
• Damaged door frame / intrusion beam: Structural damage that compromises side-impact protection or prevents the door from latching correctly.

• Bare shell vs. complete door: This listing is for the bare shell without trim. If the customer requires a complete door with trim, glass, and hardware, that is a different scope and must be specified separately.
• Paint preparation is required: The shell is supplied unpainted. Confirm paint compatibility and preparation requirements with the body shop before installation.

1. 1Confirm the required part first: Verify that the replacement is the front right (RH) bare shell and that the hinge and latch mounting points match the original door.
2. 2Remove the original door: Support the door weight with a jack or stand. Disconnect the door check strap, wiring harness (if any), and hinge pins/bolts. Note the hinge shim configuration for alignment reference.
3. 3Transfer hardware: Transfer the original hinges, latch, handle, glass, regulator, and trim (if retained) to the new shell. Inspect hinge pins and bushings for wear — replace if loose.
4. 4Pre-fit the new door: Mount the new shell on the hinges and check panel gaps and flushness before final tightening. Adjust hinge position to achieve even gaps at the front, rear, top, and bottom edges.
5. 5Paint preparation and finishing: The door is supplied unpainted. Clean and prep the surface according to the paint manufacturer's instructions, apply primer, base coat, and clear coat to match the vehicle's factory finish.
6. 6Install glass and hardware: Transfer or install the window glass, regulator, latch, handle, and trim. Check window alignment and operation.
7. 7Verify latch and sealing: Close the door and verify that the latch engages smoothly and the weather seal compresses evenly. Check for water intrusion points around the perimeter seal.
8. 8Road test: Drive the vehicle and listen for wind noise or rattles from the door area. Re-adjust hinges or latch if necessary.

• Inspect door hinges and latch at every service or every 20,000–30,000 km — lubricate hinges and latch mechanism to prevent wear and binding.
• Check weather seals for cracking or compression set — replace if water intrusion or wind noise develops.
• Inspect for rust along the lower door edge and seams, especially in coastal or salted-road environments.
• Avoid slamming the door — excessive force stresses the hinges and latch over time.

• Standard packing: Protective carton or crate with internal cushioning. Packaging size reference: 156 × 118 × 14 cm.
