Kenworth T660 Exterior Parts

Frequently Asked Questions About Kenworth T660 Exterior Parts

Will these exterior parts fit my specific year model T660, and are there differences between model years?

Kenworth T660 trucks were produced from 2008 to 2016, and while many exterior parts are interchangeable across these years, there are some notable differences. Most bumpers, grilles, and side panels fit 2008-2016 models, but headlight assemblies changed in 2013 with updated LED options. Hood variations also exist between pre-2011 and post-2011 models. Always verify the specific part number against your OEM or contact our support team with your truck's year and OEM for guaranteed compatibility.

What's the difference between chrome, stainless steel, and painted bumper options for the T660?

Chrome-plated steel bumpers offer the classic mirror finish but require regular polishing and can pit or rust if the chrome is damaged. Stainless steel bumpers (typically 304-grade) provide excellent corrosion resistance and maintain their appearance with less maintenance, though they have a slightly different shine than chrome. Painted bumpers are the most economical option and can be color-matched to your cab, but may need repainting after stone chips or minor impacts. For harsh winter conditions or coastal operations, stainless steel provides the best long-term value.

Can I install these bumpers and exterior parts myself, or do I need professional installation?

Most T660 bumpers can be installed with basic tools and 2-3 hours of work, requiring standard wrenches, sockets, and a helper for lifting. The main bumper typically uses six mounting bolts accessible from behind. However, if you're adding fog lights, turn signals, or air connections, professional installation is recommended to ensure proper wiring and DOT compliance. Fiberglass hoods and fenders require more careful handling and alignment, often benefiting from professional installation to prevent stress cracks.

How do aftermarket bumpers compare to OEM Kenworth parts in terms of fit and quality?

Quality aftermarket bumpers from reputable manufacturers often match or exceed OEM specifications at 30-50% less cost. Look for parts made from 16-gauge steel minimum for bumpers, with proper mounting holes pre-drilled. The main differences are usually in chrome quality and warranty length. OEM parts typically carry a 1-year warranty while aftermarket ranges from 90 days to 1 year. Fitment issues are rare with established brands, but always check that mounting brackets and hardware are included, as some aftermarket options sell these separately.

What should I know about weight ratings and DOT compliance when replacing my T660 bumper?

Your replacement bumper must meet FMVSS standards for your truck's weight class. Standard T660 bumpers are rated for trucks up to 80,000 lbs GVWR. Heavy-duty options are available for severe service applications. Ensure any bumper maintains the required 4-inch ground clearance and doesn't extend more than 6 inches beyond the frame rails. If adding accessories like light bars or moose guards, verify they don't obstruct required lighting or exceed width restrictions (102 inches total). Keep documentation of DOT compliance for inspection purposes.
