For truck owners replacing damaged plastic exterior parts, the right choice depends on the panel location and exact vehicle fitment. The ALMULOO Isuzu side panel is a model-specific body-panel option, while the ALMULOO rocker cover and FitParts fender liner address Silverado and Sierra underbody areas. PIT66 offers Tundra fender fillers, and UNIGT supplies GM clips for securing plastic panels. Confirm your truck’s year, model, cab, and side before ordering.

ALMULOO Isuzu Truck Side Panel
Best for: Owners replacing a damaged or aged side panel on a compatible medium-duty Isuzu truck. This is the most direct match in the list for a truck body panel rather than a fastener or wheel-area component.
The panel is made from ABS plastic and is described as a replacement for 2005–2007 Isuzu NPR, NPR-HD, NQR, and NRR trucks. Its exterior design is intended to follow the vehicle’s existing lines. Check the exact truck series and model year before ordering; the listing does not specify further panel location or side details in the provided information.
Limitation: Fitment is restricted to the stated 2005–2007 Isuzu models, so it is not a general-purpose truck panel.
ALMULOO Silverado Rocker Panel Cover
Best for: Owners of a compatible 2014–2018 Chevrolet Silverado 1500 or GMC Sierra 1500 Crew Cab who need a plastic rocker panel cover. The part is made from heavy-duty polyethylene and has a textured finish. The stated design follows the truck’s body lines, making it a suitable choice when replacing a worn cover or refreshing the rocker-area appearance.
The manufacturer identifies this cover as useful in muddy, slippery, or rugged terrain and describes it as providing support and stability. Choose it if your truck matches the listed year, model, and cab configuration.
Limitation: The specified fit is for Crew Cab models only. Verify cab style and vehicle details, since the listing does not claim fitment for other configurations.
FitParts Silverado Front Fender Liner
Best for: Silverado owners replacing the front-right fender liner on a 2014 or 2015 Chevrolet Silverado 1500. A fender liner is a wheelhouse component, so this option is more appropriate for that specific area than a full exterior body panel.
FitParts describes the part as a direct-fit replacement for the original factory component. The listing also states that it is brand new and factory sealed and meets or exceeds DOT and SAE compliance standards. Confirm the side and model year before choosing it, especially if you need a left-side liner or a part for a different Silverado generation.
Limitation: This listing specifies only the front-right position and 2014–2015 Silverado 1500 fitment.
PIT66 Toyota Tundra Fender Fillers
Best for: Tundra owners seeking a pair of front fender fillers for model years 2014–2021. The set includes driver- and passenger-side pieces and lists OE reference numbers 539320C903, TO1242101, 539310C903, and TO1243101.
These fillers are made from polypropylene plastic. The product information describes impact resistance and says the parts help protect the wheelhouse from rocks, soil, and salt. Choose this set when both front filler pieces are needed and the truck matches the specified model years.
Limitation: Fitment is stated for 2014–2021 Tundra models. Confirm the reference numbers and vehicle year before purchase rather than assuming compatibility with other Toyota trucks.
UNIGT GM Fender Liner Clips
Best for: GM owners replacing retainers that hold plastic fender liners, wheelwell parts, under-hood panels, bumpers, or door trim. This is a fastener assortment rather than a body panel, but it can be relevant when installing or securing replacement plastic parts.
The package includes 40 clips that replace GM OEM numbers 11589292 and A20991 for inner fender liner, wheelwell, and under-hood panels. It also includes 40 push-pin retainers for plastic inner-bumper parts and exterior trim, plus 40 door-trim clips with listed replacement numbers. Match the clip type and reference number to the fastener removed from your truck.
Limitation: The assortment covers specified GM applications; it is not a universal guarantee that every clip will fit every truck panel.
Buying Guide: Choosing Plastic Truck Body Panels
Which part of the truck are you repairing?
Identify the damaged area before comparing products. A rocker panel cover sits along the lower side of the cab, a fender liner covers the wheelhouse area, and a fender filler is a separate component near the fender. Side panels are another distinct body part. These items are not interchangeable, even when all are made from plastic.
How can you confirm fitment?
Use the year, make, model, trim or cab style, panel position, and side of the vehicle. Compare any listed OE or replacement part numbers with the number for your original component. For example, the Silverado liner here is front-right only, while the rocker cover listing specifies Crew Cab models. Ask the seller or consult a parts professional if a key fitment detail is missing.
What material and construction details matter?
The listed products use ABS, polyethylene, or polypropylene, depending on the part. Compare the material description and intended location, but do not assume one plastic type is automatically better for every repair. A replacement should match the vehicle application and the function of the original component.
Do you need new fasteners?
Clips may break or become damaged during panel removal. Check whether the replacement panel includes fasteners; the supplied product information does not say that these panels include them. If buying clips separately, match their shape, size, and reference number to the original fastener and its mounting hole.
Frequently Asked Questions
Are plastic truck body panels universal?
No. Fitment varies by truck, model year, cab style, panel position, and side. Use the product’s stated application to narrow the selection.
Is a fender liner the same as a fender filler?
No. A fender liner covers the wheelhouse area, while a fender filler is a separate fender-area component. Check the part name and location before ordering.
Can an assortment of clips fit any truck?
No. Multi-size kits may cover several applications, but individual clips still need to match the mounting point and vehicle. Use listed part numbers where available.
Should I replace clips when changing a panel?
Inspect the removed clips. Replace any that are broken, distorted, or no longer hold securely, and confirm that the replacement clip matches the panel and mounting hole.
