JK Wrangler Spare Tire Bump Stop DIY for Bigger Rollers

JK Wrangler owners can stabilize their big spare tire with items from the hardware store.

When you upgrade to larger wheels and tires on your Jeep Wrangler, you also upgrade the spare. In some cases, a larger wheel-and-tire combo requires an aftermarket tire carrier and in most of those cases, the bump stop on the swing door will no longer contact the back of the spare tire. There are aftermarket kits that include larger bump stops, but for those JK Wrangler owners who just want to stabilize the spare tire without spending much money, you are in luck.

Forum member Ginxer86 shared a simple do-it-yourself write-up that will allow you to secure your Wrangler’s spare tire for less than $20. Not counting the drive to the hardware store, it should take less than 10 minutes, as well.

Wrangler Spare Bump Stop DIY

When the OP posted his DIY write-up in the forum, he provided the following information.

Hey guys sorry this kinda isn’t a DIY/Write up because it was so easy.

But thought it may help someone out there who has a 33+ tire on their tail gate with negative offset wheels. I read that the bump stops that they sell are foam and are POS. I didn’t want to go the tennis ball route since it kinda looked ghetto.

I recently upgraded to 33’s and was more than an inch off the factory bump stops. So I picked up 2 of these couplings in the plumbing section at home depot for $6.50 each and I slapped it over the factory bump stops they fit perfectly snug. They are hard rubber.

Didn’t need to buy anything else or cut anything. It even came with the screw clamps. But I removed the end ones as it’s not needed. Only need one on each.

5 min job!

In the discussion following the initial post, the OP provided more details on the product that he used.

Here guys is the product information.

Fernco Model # P1056-150/125 Internet # 100044154 Store SKU # 320518

Finally, the OP included a series of pictures of his homemade spare tire bump stop kit.

Cheap, Easy and Secure

There are lots of things that you can add to your factory JK Wrangler spare tire bump stop to help stabilize an aftermarket wheel-and-tire package. Some people use rubber hose to create a similar design to what is shown here, but that doesn’t clamp down in place. Some people attach tennis balls or hockey pucks to the factory stops, but that doesn’t look as nice at the plumbing coupler.

If you want to stabilize the spare on your JK Wrangler without spending much time or money, this DIY is the best option we have seen thus far.

"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.

"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
