Frequently Asked Questions About Kenworth T660 Grilles

Will this grille fit my Kenworth T660 without modification?

Grilles in this category are designed to match the factory grille opening on the Kenworth T660, so they typically install using the original mounting points and hardware. However, production years can bring minor variations, so it's a good idea to compare the part's specifications and photos to your truck or check with our team before ordering if you're unsure.

What materials are these grilles made from, and how do they hold up?

T660 grilles are commonly offered in materials like aluminum, stainless steel, or heavy-duty plastic/composite, depending on the specific style and finish you choose. Aluminum and stainless options generally offer strong resistance to road debris and corrosion, while composite grilles tend to be lighter and more budget-friendly. Check the product description for the exact material used in each listing.

Can I get a grille with or without bug screen openings?

Yes, many T660 grille styles are available both with louvers or mesh openings for airflow and bug screen mounting, and as solid-face versions without openings. If airflow to the radiator or A/C condenser is a concern for your application, look for a listing that specifies open or louvered design before purchasing.

Do these grilles come pre-painted, chrome-plated, or unfinished?

Finish options vary by listing and may include chrome-plated, painted, or raw/unfinished surfaces ready for paint matching. If a specific finish or color match to your truck is important, check the product title and description carefully, since not every style is offered in every finish.

Is installation something I can do myself, or does it require a shop?

Most T660 grilles are designed for a straightforward bolt-on installation using the existing mounting hardware and holes, which many owner-operators handle themselves with basic tools. That said, if your grille includes integrated components like light mounts or requires trimming to fit trim pieces, you may want a shop to confirm proper alignment and fitment.
