Found these Staun internal beadlocks on an Off-road magazine so i called Harry at Staun Products and asked him if they would work at a high rate of speed of 150mph+. He said they would and he sent me a set to try. They make many different sizes, A size they dont offer right now is for a 13inch rims but Harry told me if there is enough request he would make them. It was easy to install and only had to drill 1 hole.
Just wanted to let everyone know there is an alternative to buying new wheels with beadlocks on them.

We have these on our 15x8 Spin werkes wheels on 26x10-15 and we have ran our personal best of 9.58 and 155mph on these. These internal bead locks work great and they are a very good alternative to putting screws on rims

Harry is very helpful, here is the site where u can find more info on these http://staunproducts.com/

 

That's a good find. I'm going to look into this some more.

Thanks for sharing!

 

My buddy has these on his wheeling/rockcrawler. we have driven with all the air let out a few times and have never popped a bead. I am pretty sure they have a video on their site of a truck with 44's completely flat being dragged sideways and doesnt break a bead.

 

also what is the price? arent they around 700 bucks for so.

 

They are not the same "bead lock" as you need in drag racing. lol

The reason you bead lock a slick is so it wont turn on the rim, unlike that system which only keeps the bead from popping off and does nothing to keep the bead from spinning on the rims. Same name, two totally different functions.

 

Yea there's pictures off that truck on there website.


They are actually not that expensive. You can get a whole set (4) for 700. Price is around 200ish for each wheel depending the size. I looked on there website and they had a special going on the month of march

 

according to their website this thing will stop the rim from spinning in the tire as well..

There is a huge difference in keeping a tire from spinning rim in those environments and a sticky slick on a sticky track with 5/6/7/800 plus whp being applied....

Think about it people have torn screws out of the beads attempting to keep the rim/tire from spinning...

 

We have made more than a dozen passes on these with more than 900hp and havent spun them. Thats the reason im posting them up because they work

 

Looks like Hector needs to mark the slick on the rim and do a lot of testing..

Looks like a good idea to me though..

 

They have been marked but we sure are gonna do more testing

 

Hi, I'm Harry Lewellyn, Director of Operations, Staun USA Inc

Staun internal beqdlocks are relatively new to drag racing, so I welcome your scrutiny. I'm a belt a suspenders guy, so extensive testing is encouraged.

I have one other known drag racer using Stauns and he just took first at the AZ NHRDA event. He's putting 1100 ft-lbs to his wheels and he has one year plus on the same set of tires. Here's his link.

Hey Harry,

I have a question about these beadlocks....

Based on the picture above from your website it looks like the tire is not fully "deflated" due to the Staun Beadlock.... Is that picture implying that the tire will not wrinkle or flex as much as a different style of beadlock?

 

Screws in the rim is a good point, it's a bad idea. IMO tires will tear for just that reason, there is a f$%#*^' screw going through the sidewall. I would scrutinize the balance issue above all. "Slickrock" provides ample traction, this beadlock is made for off road use in a 33+ inch tire most likely on a 15" rim. Physics is not in it's favor, I've heard it works. Not from the OP, I own a Samurai.

 

Tire wrinkle will be a function of the tire, it's condition and vehicle weight. The only thing I can say for sure with a properly inflated beadlock is that the tire will only be able to go down to the point where the OD of the beadlock and the inner portion of the tire tread touch.

 

How fast have you gone with that 900+hp?

On another note, I think the internal beadlock system that staun has come up with will be in the way on cars like ours. When you run the pressure that we run on the fwd cars it seems as though the tire wont be able to do its job as the internal system will be in the way.

Also as far as screwing wheels to the tires, there is nothing wrong with it at all. Been doing it for a while, the one and only reason i dont send my wheels to reds to have them truly beadlocked is the weight difference between the beadlock system and the screws.

 

Wow, I never thought I would see these on here.

I know guys that have used them before in offroad rides, and from what I was told they look like a good idea but are really a big PITA to use and really didnt work that well (for both guys that I know of). If i remember right, they both ended up going back to his conventional bead-locked wheels.

Edit: So I just got off the phone with the guy and he was telling me about them and from what he said: They work good in a small tire ride (were talking 35's) as apposed to what he was running at the time (46's). Basically the staun's would not hold the tire from spinning and would actually spin the staun on the rim and rip the air valve off inside the wheel. I know the guy isnt a drag racer, but basically they are hard to mess with cause now you have a tire inside a tire. If you change the press. of one it changes the other too, and he seemed to think you would have a hard time keeping a consistent tire press.

Just my 0.02$

 

car has only went 9.58@155 on 30psi made 830hp@30psi The car is on 40psi now should be going to the track this weekend.
these beadlocks seem to be working just fine.
