Kenworth T660 Interior Acc.

Frequently Asked Questions About Kenworth T660 Interior Accessories

What year models do these accessories fit?

These interior accessories fit 2008–2017 Kenworth T660 models. Some early 2008–2009 trucks may have slight differences in dash and door panel mounting points. If unsure, verify your OEM specs or contact support before ordering.

Are the floor mats and seat covers built for daily commercial use?

Yes. Floor mats are made from heavy-duty rubber with deep grooves to trap mud and water. Seat covers are available in genuine leather or commercial-grade vinyl with reinforced stitching. Both resist extreme temperatures (-40°F to 140°F), oil, grease, and UV exposure. With proper care, most last 3–5 years under heavy use.

Do I need special tools or professional installation for dash and trim accessories?

Most items install with basic hand tools like a Phillips screwdriver, trim tool, or 7mm/10mm socket. Dash trim uses factory mounting points and clips and installs in about 15–30 minutes. Electrical accessories may require basic wiring knowledge. Most installs take 30–60 minutes and include instructions.

What’s the difference between OEM-style and aftermarket chrome interior accessories?

OEM-style parts match factory specs for a stock look and exact fit. Aftermarket options may feature thicker chrome and custom design details. OEM ensures precise fitment, while aftermarket offers added durability and style. Both use factory mounting points and hardware.

Will adding aftermarket gauges or switches void my warranty or affect resale value?

Installing gauges or switches in factory-designated locations typically will not void your warranty. Drilling or modifying the dash may affect coverage. Professionally installed accessories can maintain or increase resale value. Keep original parts if you plan to return the truck to stock.
