Q: What is a Beadlock?
A beadlock is a specialized device used on wheels, primarily in off-road and racing vehicles, to secure the tire’s bead (the inner edge of the tire) to the wheel rim. It is designed to prevent the tire from slipping or coming off the rim during low tire pressures, which is common in off-road driving when vehicles need to deflate their tires for better traction on rough terrain, such as sand, mud, or rocks.
How a Beadlock works:
A beadlock consists of an inner ring and an outer ring that clamp down on the tire’s bead, holding it firmly in place on the wheel. This prevents the tire from separating from the wheel, especially when the tire is under low pressure, which would otherwise cause the bead to unseat under heavy loads, impacts, or extreme cornering forces.
Key Benefits of Beadlocks:
- Prevents Bead Unseating: By securing the tire bead tightly, beadlocks reduce the risk of the tire popping off the rim during off-road driving.
- Lower Tire Pressure: Drivers can run lower tire pressures for better traction on soft or uneven surfaces without worrying about the tire losing its seal.
- Enhanced Off-Road Performance: Beadlocks are commonly used in off-road, rock crawling, and racing vehicles where extreme tire conditions are expected.
Beadlock Wheels:
- Beadlock wheels have an additional ring that bolts around the edge of the rim. The tire’s bead is placed between the rim and the beadlock ring, and bolts are tightened to clamp the tire in place.
- These wheels are usually found in rugged off-road vehicles, rock crawlers, and some motorsport applications where wheel integrity under extreme conditions is critical.

Excellent product! I installed mine as my first step into getting some more performance out of my M3P for Autocross. The front and rear sway bars along with some wider wheels and stickier tires really took my lap times to the next level. I would say, if you drive hard with these sway bars like I...

I installed these with the race pads.. The car is significantly better at stopping, the pedal feel is fantastic. One of the biggest addtional things I noticed was the decreased weight.. The wheels done thud as hard over bumps, and comfort setting now feels like actual comfort.. The wheels also...

Purchased the sway bar for my plaid about a year ago after hearing good things about it on the Tesla forum. Unfortunately, I got super busy and I didn’t get a chance to install it until recently. Very happy with the purchase and there’s a very noticeable improvement in handling. The car also...

I got the FUCAs installed on my 2018 Performance Model 3 and wished I hadn’t waited so long to do it! Now I can do proper alignments with camber on the front, not possible to do with the stock control arms. You can also put custom wheel sizes with super wide tires on the front without worrying...

I installed this sway bar today. I was shocked by the outcome in terms of handling. It feels almost playful in the corners now, where as before it felt like it was exclusively about straight lines and that corners were sort of something to get through. It's on a medium setting, and I think if I had...

I installed this light bar on my Cybertruck, with the roof rail, a little over a month ago and absolutely love it. Both the light bar and roof rail are very well made and the 34K+ raw lumen turn night into day!. Things to consider:
- This light bar, with the roof rail, mount solid to the vehicle...

I really like the new moderate lowering spring for my Model Y performance.
The set lowered the car by roughly 1 inch (2.5cm)
I have the feeling that the car provides a smoother ride than stock.
You feel it when driving over small bumps. The car is still stiff but I like it better that stock and...

Real cool suspensions the car drives smooth and quite. Made a real difference to the drivability and now I really enjoy driving the car. Absolutely recommend it if your factory shocks have failed. Mine failed in 5 years.

Great add on for your Tesla to really dial in the alignment! Great time to do it is when you’re lowering your car already or getting an alignment anyways. Improving tire wear is very important for me as I drive a lot and been getting more miles/set than ever before. Highly recommend!

Installed this on my CyberBeast in my own garage. The instructions provided were top notch with outstanding attention to detail. I installed the bar in the middle position. On the first turn I noticed the decrease in body roll. The turn in and mid turn stability is much improved. I am very...

The ascension front fascia makes my model 3 look so much sportier and aggressive. I’ve had it on my car for over a year now and I love it. The car looks way better than stock. This is how the car should look coming out of the factory.

Exactly what I wanted. Much better appearance. Beautiful stance. Both stiffer in the corners and smoother on the regular road imperfections. Feels more tuned and prepared. Will recommend to all my Tesla owning friends.

This definitely helps cool down my drive unit quicker. I'm able to run a hot lap at the track, then a single cooldown lap to bring the drivetrain temperature back into the green. It was awesome seeing it cool down within a lap at Buttonwillow.

I tried the sports dynamic kit because I wanted a lower center of gravity for autocross. That it has a stock/sports spec that can be relatively easily modified was a draw, in addition to the idea that these are a fixed bracket that sets in place. The installation was indeed quite straight forwards,...
