Great for High Mileage vehicles
Size: 12 fl. oz. (Pack of 1)
Added into my 2014 Dodge Grand Caravan with 100k miles before a family trip and eliminated knock, slow starts and improved our gas mileage by about 10% I think! super easy to add to the oil and very happy with results.

Great assortment of clips—fits well and saves a trip to the dealer
Color: 40pcs
Picked up this 40-piece set to replace missing/broken push-type retainers on my bumper/fender liner area. The assortment is a solid value—having extras on hand is way cheaper than buying a few at a time locally. The clips I used snapped in securely and held the panel tight without rattles.
Tip: match the old clip’s size before installing (hole diameter + stem length). I tested a couple first to confirm fit and then finished the job. For basic trim/under-cover repairs, this is an easy, cost-effective kit to keep in the garage.

OEM Quality
Color: 40pcs
These fit perfectly! They are easy to install and very durable! I have no doubt that they are holding everything in place. They are also very easy to remove and do not break during removal, which is great.

They’re okay
Color: 40pcs
These fender clips are just okay. They fit reasonably well and did the job for a quick fix, but the quality isn’t the best. Some of them felt a bit flimsy, and a few broke during installation.
If you’re in a pinch and need a temporary or budget-friendly option, these will work. Just don’t expect OEM-level durability. Decent for the price, but not great.
