Late-model (2007-newer) GM pickups and SUVs don’t come stock from the factory with inner liners on the rear fenders. This leaves them trucks with an unfinished look. Worse yet, for contractors and construction company owners, it leaves the inner sheetmetal of the rear fenders directly exposed to the constant bombardment of rocks, salt, and other debris slug up by the rear tires.
The good news is GM rear fender liners can be installed for less than $75 and a 20-minute investment in time.
Inner fender liners are available from a number of sources, including your local GM dealer. GM #19166676 covers the set. If your local GM dealer isn’t cutting you a fleet discount and you want to save a few dollars, GM Parts Direct sells them online for less than $70. It typically takes 3-4 days for them to arrive via UPS.
Installation is, well, a snap; the rear fender liners literally “pop” into place. They are secured by three autobody plastic push pins and four self-tapping screws – all supplied with the kit.
Truck Supply & Outfitters in Tuscaloosa, Alabama, says they install GM rear fender inner liners for customers on a regular basis, and showed us just how simple the job is for the do-it-yourselfer. The images in our gallery below show the steps. – Bruce W. Smith
