So I've been recently fixing up my 2004 Chevy Silverado 1500 and my passenger fender liner is full of holes and cracked and my driver side which is brand new is now shredded due to the clips that hold it pulling through due to it being too flimsy and it rubbing on my tire for over 15 miles. Nowhere has the passenger one in stock and I've been looking for weeks. Now my question is where do I find a good quality fender liner that isn't flimsy and is a good rigid plastic? Most of the ones I see online are flimsy but still expensive. Is it worth calling the dealership to ask them if they can get any OEM ones? I figured I would ask her since someone might be able to lead me in the right direction. Thanks in advance!

Check with a body shop new you. They should be able to help you out.

How about a salvage yard?

Find a parts truck and save some money then sell off the parts you don’t need and you get free parts that way. I do that with the old D50 trucks I collect.

a you pick type scrap yard or parts truck

if you want more durable , you might line them with rubber mud flaps the big ones like the sell at the farm store for trucks and trailers
SS hardware and fender washers to mount them

you said what you have has holes from the clips , can you post a picture?

Husky makes fender liners that are very durable and reasonably priced. Eric
