Why You Should Use Well Nuts for Your Widebody Kit

Why You Should Use Well Nuts for Your Widebody Kit

Widebody kits can have a significant impact on a car's exterior appearance and have become a must-have modification for many show builds. What we have found being in the hardware business, is that while the kits look amazing (when done correctly) most of the hardware used to secure the kits to the car is less than ideal.   

Most kits will only come with self-tapping screws for mounting the body kit. As many shops know, and owners who have used the included hardware have found out, this is a terrible long term solution for mounting the kits. As a result, people started using a combination of rivnuts (nutserts) and bolts. While this is better than using self-tapping screws, rivnuts have their downfalls.

One, you have to have a special tool to install the rivnuts that most people won’t already have in their toolbox. Two, once they are installed, they do not create a seal to prevent water from seeping between the rivnut and the body which can lead to rust issues later. Three, they can eventually come loose enough from vibration to create an annoying rattling noise. Finally, they will eventually fail, which will require you to drill them out to replace them. After dealing with these issues first hand, we decided to search for a better solution.

After a lot of research, we found out about well nuts, which are typically used in boating applications because of their resistance to weathering and water. Here are our top 4 reasons you should use well nuts as your widebody mounting solution:

  1. Well nuts do not require a special tool to install. All you have to do is insert it and use a bolt to tighten and expand the rubber portion of the nut to create a strong hold.
  2. When the well nut expands it completely seals the drilled holes created for mounting and prevents water from seeping in and creating any corrosion build up on the body of the car.
  3. The well nuts rubber absorbs vibration and prevents any negative effects caused by it over time and eliminates annoying rattling sounds.
  4. Just like rivnuts, well nuts do have a life cycle and will need to be replaced when the rubber dries out. The difference is that well nuts are easy to uninstall. Just take out the bolt to allow the nut to expand and simply pull it out.

"I like the well nut for so many reasons. The rubber allows me to bolt a widebody kit up to a car for a test fit and when it's ready for paint we can just pop them out."
