Need both front and rear?
If you want a full set (front and rear), please select the “Set” option in the “Location” dropdown list above. This will make sure you are not charged excessive shipping.
If you have ever removed those little white plastic clips on a JL, you have undoubtedly formed an opinion about them. With the OEM fender configuration, they are perfectly sufficient. However, when you split the fender and remove the plastic bracing, they become a weak link. More accurately, we are asking them to do something they were not designed to do. For this reason, we have developed a product to replace. Our Jeep JL Fender Retention kit provides substantially more clamping force and a better mechanical connection.
Unlike other companies that sell a “bolt kit”, we have designed a rectangle washer that utilizes existing square holes on either side of the center pin hole. The studs in our plastic washer grab those square holes and provide a very secure mounting system and prevent you from over-tightening the bolt, which in turn, prevents you from smushing (technical term) the plastic around the bolt. Take a close look at the fender without the white plastic clips installed. You’ll notice that there is a split where the bolt goes. Without our plastic washer, the fender could rip out and allow the bolt to slip through the slot. The best way to prevent that with a bolt-only kit is to over-tighten the bolt.
We use a very specific nutcert with our kit. This nutcert does not require drilling to go into the vehicle. We searched numerous suppliers to find this specific component. All of the other nutcerts we tested required drilling the fenders. This is a no-drill kit.
Each kit consists of the following:
- Plastic fender washers
- 6mm nutcerts
- 6mm wide flange head bolts (zinc plated)
Basic Installation Process
As with most things, there are a lot of ways to install a rivet nut. There are rivet-nut specific tools available online. There are also quite a few ways to do this without any special tools. One common method is by using the stack of hardware (not included) shown here.
Using this method, you would assemble the hardware stack as shown to the right, thread the bolt into the rivet nut, and then insert the entire assembly into the hole in the Jeep fender.
Next, you would use a box end wrench to hold the 8mm nut. Then, tighten the bolt to crush the rivet nut. If you have access to a small impact driver, this is a good time to use it.
Once the nut is crushed, you can remove the bolt and remaining hardware stack, leaving the rivet nut installed in the fender.
NOTE: Rear Kits
In order to simplify our product offerings, the rear kit (for JL and JT) includes 26 sets of bolts, nutcerts, and location washers. On the JT this assumes that you will not be retaining the black plastic trim that runs along the bottom edge of the rear flare. If you want to retain that trim and wish to attach it to the body, let us know before your order ships and we will be glad to include the extra two sets at no cost.
For the JL, you will have two extra sets of bolts, nutcerts, and washers if you do not retain the rear flare trim. If you do retain the rear trim, you will use all 26 sets.
If you are using our inner fenders, you will not install the nutcerts into the body for these four bolts on each side.
The mounting brackets that ship with our inner fenders already have nutcerts in them for these holes.
Our inner fenders will ship with four of the fender retention washers for each side. You’ll need to purchase this product to replace the remainder of the white plastic clips.

I purchased the front and rear kits along with High-Line braces and all I can say I can say is that it is shocking the difference that the kit’s “washers” provide with respect to how much better supported the fenders feel. Great use of additive manufacturing!

Perfect nutsert size for 2020 JL, and perfect (3D printed?) clip replacements. It was a breeze to install, and are so good that even Rugged Ridge Max-Terrain fender flares, which are flimsy, actually are less flimsy. Brilliant design, kudos to AAL. I’m blogging and posting to Facebook about these bad boys!
Thanks, Don! Appreciate the kind words. Send us a link and we’ll repost your blog post.

Just installed mine. What a difference. Sure wish I installed them sooner. Would have saved me having to buy replacement High-Line light. I have the Lower light mount add on and one nut fell out after wheeling in Moab. Headed into a 40 + mile an hour headwind and going 60 the light began to pivot. The force of that was just right that all the lower plastic poppers popped out and if not for the 2 bolts from the High-line bracket, the entire fender would have flown off. It was just flapping in the wind. Got lucky with minimal damage to fiberglass, but the force of the tweaking did break my high-line light. Anyway installed these with the replacement light and that fender is not coming off in those conditions again for sure!!!!!
Thanks, Todd! Yeah, most people don’t realize that if they shouldn’t reuse the white plastic clips. They’re only good for the one-time install at the factory. When you pull the flare off, it bends the ears of the clips backwards, reducing their ability to retain the flares. Glad the damage wasn’t too bad. You should be good now, with the install of the FRH kit.

These are the perfect addition to stabilize the Jeep fenders. I live in Arizona and my plastic clips were starting to loosen (my guess is from the sun). I swapped the clips out with this kit (both front and rear) and love the finished product! No more vibrating fenders driving down the freeway. My biggest complaint is my set didn’t come with any directions or information on how to install…which, they are very self explanatory once you get going, but youtube had several install videos detailing the proper process. Also, do yourself a favor and pickup a rivnut install tool — it will make this install SO MUCH easier as opposed to using the homemade method mentioned in the description. (Harbor Freight – $40, not bad). Either way, big fan, 10/10 recommend for the JL
Thanks, Justin! Glad you like them. The label in the bag should have had instructions printed on the inside of it. I apologize for the oversight of that not being printed correctly. We’ll make sure and double check those.

Inarguably the best fender retention hardware. I installed this along with the high line fender braces, and the result is a solid fender that won’t flop even at greater than highway speeds. A rivet nut tool makes installation a breeze and saves time, highly recommended. This is a must-have if you’re splitting your fenders.
