Frequently Asked Questions About Kenworth T660 Roof Trim

What year models does the T660 roof trim fit, and are there different versions I need to know about?

The Kenworth T660 roof trim is designed to fit model years 2008-2017. There are two main variations: the standard cab version and the extended cab version. The mounting points differ slightly between early models (2008-2012) and later models (2013-2017) due to minor cab design changes. Always verify your specific cab configuration and year before ordering to ensure proper fitment.

What materials are available, and which holds up best against weather and UV exposure?

T660 roof trim is available in three primary materials: stainless steel, chrome-plated ABS plastic, and powder-coated aluminum. Stainless steel offers the best long-term durability and UV resistance, typically lasting 10+ years without fading. Chrome-plated ABS is more budget-friendly but may show wear after 3-5 years of exposure. Powder-coated aluminum provides a good middle ground with 7-8 years of expected life. For trucks operating in harsh climates or with heavy sun exposure, stainless steel is the recommended choice.

How difficult is the installation, and what tools or modifications are required?

Installation typically takes 2-3 hours and requires basic hand tools including a drill with metal bits, rivet gun, measuring tape, and masking tape for alignment. Most roof trim kits use the existing mounting holes, but some aftermarket options may require drilling 6-8 additional holes. No cutting or welding is necessary. The most challenging aspect is achieving proper alignment, so having a helper is strongly recommended. Professional installation usually runs $150-300 if you prefer not to DIY.

Will aftermarket roof trim affect my radio antenna or CB reception?

Quality roof trim should not interfere with antenna reception when properly installed. However, metal trim pieces installed too close to antenna bases (within 6 inches) can cause signal degradation. Most T660 roof trim kits are designed with antenna clearance in mind, featuring cutouts or spacing for standard antenna locations. If you have custom antenna placement, measure clearances before ordering or consider trim pieces that can be modified on-site.

What styles and finishes are available, and do they match OEM accessories?

T660 roof trim comes in several styles including smooth, ribbed, and diamond plate patterns. Finish options include mirror polish, brushed stainless, chrome, and black powder coat. For OEM matching, the standard Kenworth chrome finish is a #8 mirror polish on stainless or bright chrome plating. Most aftermarket manufacturers offer finishes that closely match Kenworth factory accessories. Ribbed designs tend to hide minor imperfections better and are popular for working trucks, while smooth finishes provide a cleaner, more refined appearance.
