Front Left Door Trim Pad 8978526450 / 8-97852645-1 For ISUZU NPR66 NKR55 4KH1 — Interior Panel, Lightweight Construction

The Front Left Door Trim Pad with OEM references 8978526450 / 8-97852645-1 (factory number 8-97852645-TZ) is a verified replacement interior panel for the ISUZU NPR66 and NKR55 light truck platform equipped with the 4KH1 engine. This is the front left-hand (LH / driver side) door trim pad — the molded interior panel that covers the inner metal door shell, providing a finished cabin appearance, mounting provisions for the window control and door handle, and factory-style cutouts for all controls.

The unit is confirmed by multiple independent listings as "DOOR TRIM LH" and is described functionally as providing interior decoration, door opening/closing assistance, window switch mounting provisions, sound insulation, and occupant safety protection. The paired right-hand (RH / passenger side) counterpart uses reference 8978526440 / 8-97852644-0.

This is the front left door trim pad. The right-hand counterpart uses 8978526440 / 8-97852644-0. Left and right panels have mirror-image control cutouts, handle openings, and speaker provisions. They are not interchangeable.

The reference data does not explicitly state whether this trim pad is provisioned for a manual window crank or a power window switch. The functional description mentions "window switch mounting" (glass lift switch arrangement), which suggests a switch provision, but the exact cutout type must be confirmed against the original panel. Do not assume manual or power configuration without physical verification.

This listing covers the trim pad only. Mounting clips, window switch, door handle bezel, and hardware are not included unless explicitly stated. Confirm package contents at inquiry.

• ConfirmMaterial and Colour NOT Publicly Specified: The accessible reference data for 8978526450 does not publish a material specification or a confirmed colour. The brand is listed as CHINA AFTERMARKET or YIMI. Confirm material and colour at inquiry — do not assume a specific finish without supplier confirmation.

• Cracked or broken panel body: Impact damage, UV degradation, or improper removal can crack the plastic substrate, affecting appearance and mounting integrity.
• Broken or missing mounting clips / tabs: The panel is retained by factory-style clips. Broken retainers cause rattles, sagging, or partial detachment.
• Damaged window control cutout: A cracked or distorted switch/crank opening prevents the control from seating or operating smoothly.
• Damaged speaker grille or handle cutout: A cracked grille or distorted handle opening degrades interior appearance and prevents proper component fitment.
• Delamination or peeling of the surface finish: The surface skin can lift or peel over time, particularly in hot climates or high-use fleet vehicles.
• Stained or warped panel from moisture intrusion: A compromised door seal can stain or warp the interior panel.

• Left vs. Right is the first check: This is the front left (LH) trim pad. The front right (RH) uses 8978526440 / 8-97852644-0. Do not interchange left and right.
• Control cutout is the second check: The reference data describes "window switch mounting" but does not explicitly confirm manual crank vs. power switch provision. Physically compare the control opening against the original panel before ordering.
• Material and colour are open variables: Neither material nor colour is published for this exact reference. Confirm these specifications at inquiry — do not assume a specific finish.
• Vehicle coverage: Core application is NPR66 and NKR55 with 4KH1. Alternate reference data associates the family with NKR77. Provide the VIN for final confirmation in mixed-fleet applications.

1. Confirm the required part first: Verify that the replacement is the front left (LH) panel and that the control cutout matches the original door's configuration.
2. Remove the original panel carefully: Use a plastic trim removal tool to release the perimeter clips. Start at the bottom edge and work upward.
3. Disconnect electrical connectors (if power windows): Unplug the window switch harness before fully removing the panel.
4. Transfer reusable components: If the original window switch, crank, door handle bezel, or speaker is in good condition, transfer it to the new panel.
5. Install the new panel: Align the top edge first, then seat the perimeter clips by pressing firmly along the edge. Do not force — if a clip will not seat, check alignment.
6. Reconnect and test: Plug in the window switch (if applicable) and test operation before fully seating the panel.
7. Clean with mild interior cleaner: Avoid harsh solvents that can degrade the panel surface.

• Inspect trim pad clips and surface condition at every interior service or every 20,000–30,000 km.
• Replace missing clips promptly to prevent rattles and panel sag.
• Avoid prolonged direct sunlight exposure where possible to reduce surface degradation.
• Clean with mild interior cleaner and a soft cloth.
