Installing Fender Liners In 2008 Gmc - A How-to

[RossG]

I just got my truck and wanted to do a few simple mods to it. After researching around here for a little while, I settled on 3 of them: The DIC mod, the locking tailgate, and finally the fender liners. The DIC and locking tailgates were no brainers. After researching how to install the fender liners, I did not see any real how-to articles, so I though I would type up a quick one. If someone has already done one and I missed, feel free to link this to that post as well.

 

First step is to order the parts from your GM parts supplier of choice. I loaded my basket at GMpartsdirect.com and then took the printout to Lone Star Chevy here in Houston where they matched all the prices. For the GMC models, you need part #19166677(Chevy Guys need part #19166676) and I paid $83.85 for the pair. You only need to order one box though.

 

Tools needed:

1. Electric Drill or Screwdriver - You will need a decent one as you are using self-tapping/drilling screws.

2. Car washing supplies - Soap, Water, rags for washing, and towels for drying.

3. Floor jack and jack stands

4. Lug wrench

5. Torque Wrench - to torque your lugnuts back once you put the wheels and tire back on.

 

Now before you start this, I am not responsible if you if you somehow hurt yourself or mess up your truck or any other thing while attempting to follow this how-to.

 

After you get the parts home, you need to unpack the box and make sure that you got all of the parts. Here is what was in my box:

2 Fender Liners, 6 plastic clips, and 8 self-tapping screws

 

Here is a closeup of the clips and self-tapping screws:

 

You can install these with the truck on the ground, but I highly recommend that you jack the back end up(remember to support it with jack stands and put a brick or something in front of the front tires) and remove the rear wheels. It makes it much easier to work. You need to clean the under side of the fenders so the dirt does not scratch the paint off as you are driving your truck. The dirt in this is picture is from just 7 days of ownership!

 

After your are done cleaning the wheel wells, it is time to install your first fender liner. Note that the liners are marked LH and RH for the appropriate side. This one is for the passenger side.

 

You need to go over the top of the leaf spring and then work them in over the top of the fender lip. They are kind of pain to get to fit, but once they are behind the lip, they are pretty tight. The liners are attached at the top of the fender with three of the plastic body clips that were shown above. Simply pull the button out, push the clip in, and then push the button in until it stops. Here is what they should look like installed:

 

 

The liners are held in the front by 2 of the self-tapping screws. They have some kind of wax or coating on the tips. I was just pealing enough of it off to expose the drilling point of the screw. You can see them if you look closely in this picture. Use your electric drill here and if you have multiple speed settings, use the high speed until it start threading in and then slow down until it is snug against the liner.

 

The holes for the screws are pre-drilled in the fender liners, you just have to push the screws through the truck sheet metal. The rear of the liner is also held by 2 self-tapping screws. Again, use your electric drill here and if you have multiple speed settings, use the high speed until it start threading in and then slow down until it is snug against the liner.

 

If you took the tires and wheels off, it is now time to put them back on and tighten the lugs.

 

Next you will remove the jack stands and let the truck back down to the ground.

 

Lastly, you need get your trusty lug wrench out and torque your lug nuts.

 

Grab a beer and enjoy your new fender liners (and having to explain to the wife what exactly you just did..)

Nice write up Ross...Lone star chevy is great, they allways try and price match or at least get as close as they can. Thats where I bought my truck.

[cwrivera]

You must have been reading my mind. These instructions are great! thanks for taking the time to document.

Thanks for the writeup. Does anyone know if you can get fender liners for the 2006 Silverado 1500? I asked my Chevy dealership and the guy at the body shop told me they didn't make them. But I could have swore I have seen 1500 GMC's with them.

Nice mod...Where'd you get the liners from? I just did some searching and didn't find anything about those.

Found em, not too bad http://www.gmpartsdirect.com/results.cfm?s...number=19166676

Now that you've done it...do you think it would be possible to put them on without removing the wheels/tires??? I got mine before I left town last week and I think the directions indicated they could be done without removing the wheels but holding them up to the truck it didn't seem like that would be very easy to do with the wheels on the truck.

It would be more difficult, but it could be done.

Nice write-up, definitely a great mod.

It's real easy to do. It looks like it would be a pain but it will slip right in. I did mine with 20" wheels and ProComp tires in place. Took all of 20 mins to do.

 

I like others did not even use the screws, just the push pins and everything is fine. I just could not get myself to drill into my new truck. They stay fine without the screws and

don't even rattle. They're a great upgrade. Well worth the money.

Great post. Thanks for taking the time of taking the pictures and posting the article.

Great post. Thanks for taking the time of taking the pictures and posting the article.

 

I installed these this past week I too got them on without removing the wheels. I did have to remove the screws for Husky mud flaps. As noted in another reply... I too did not want to drill my new truck......so I just used RTV to attach and cover up the eight mounting holes....I used clear...use black it would look better...Andy

Nice write-up.

I received mine yesterday and installed them today. Very easy install. I just used the push pins and instead of drilling holes in the wells, I used a 5 to 6 in piece of double sided 3M automotive tape (which I always keep a roll of that great stuff around) which i put from hole to hole and it worked out just fine.

 

The liners are tight without needing the tap screws.

 

They really make the truck look finished.

 

I installed them without removing the wheels.

Are these available for 99-06 trucks?
