Review on 🦍 Gorilla Automotive 83-7150 Wheel Hub Centric Rings (83mm OD x 71.50mm ID) - Pack of 4: Optimized Fit for Smooth and Stable Wheels by Sheppard Priest

Amazing things. You need to put them on your TJs if you're having trouble balancing big tires. Oh, and I don't know how people break them. I've owned my Jeep TJ since it came out in 1998. Jeep and have been sharing information about Jeep TJ online for 20 years. It's a common misconception that Jeep wheels are cleat oriented after sale, so it's a good thing they don't need to be trued or trued when tightened. I am sorry to say that I have been the victim of this misinformation for the past 20 years. My jeep has suffered from minor shaking/jumping for the past 20 years that occurs at around 45 mph. I dismissed this issue as it was consistent, but no matter what I tried the issue persisted. I have oversized tires. I've tried many methods of balancing wheels, I even have dynamic wheel balancers that fit the hub with little improvement. I just mounted them on my DailyDrivenTJ bikes ;) and lo and behold, I discovered two things. Thanks to a mod I have on the Vanco brakes with thicker rotors plus the thickness of the hub balancer, the actual hub at the front doesn't touch the rim or the seal. BUT I can see how centered the wheel is in relation to the hub as it allows you to see the gap between the hub spacer and the actual hub. Looks! When I did the normal 5-hole star tightening sequence, I was "constantly" off center by a few millimeters as measured by the gap between the seal and the hub. That explains why I've been shaking for 20 years. After changing the tightening order, if I observe the distance between the axle hub and the spacer that I see, I'm tracking the movement of the wheel as it is tightened. By NOT doing the star tightening sequence, I was able to achieve even spacing around the hub and center ring. The crazy thing is that with just the front wheels on, the judder was 90 percent gone. With the rear wheels in place, my wheels trembling/jumping turned into more of the noise of those MT tires cruising down the road and became unnoticeable once I had my ears plugged. Bottom line, and I've found that the cleat-oriented method is a very inconsistent way to align the wheel to the hub. Also, due to wheel manufacturer tolerances, the star clamping pattern DOES NOT GUARANTEE center position between hub and wheel. Hub centering is the only reliable way to achieve true centering, where the wheel rotates on the same fixed axis as the hub. The center lug CAN get solid axles, but it hasn't done that for me on any of my bikes in the last 20 years. I feel so stupid for not trying this sooner and dismissing the little shaking and vibration as a "Jeep thing". This is NOT a Jeep thing. There is NO harm in using these middle spacers if they fit properly. Don't tell web hijackers to tell you otherwise. -DDTZH
