I've read a bunch of posts on Timbrens for use as bumpstops, but am still not quite sure what to think. I see the product listing here:

http://timbren.com/double-convolution/

And at least a few people went with A520-75.

How do they mount, and can they be mounted to the factory locations? In the front at least I'm happy with the factory spot. Rears might need some work.

Is there any convenient place to order them? Older threads mention Burke Spring, but their site has no mention of it at all and the thread on pirate seems to have gone stale.

Pics of installs would be great.
 
just for the record, they mount with a bolt through the center into a mounting plate of some type,(I made my own plates)...I had to carve out some of the access hole to get a socket onto the bolt. Or one could use a socket head capscrew and a long allen wrench.
 
I knew the info was out there somewhere:

This is just for the timbren bumpstops not a whole kit, as would be installed for a helper system, as timbren is known for...just the rubbers that are shown here.

Here is a chart of their AEON springs:

Found another supplier listed from 2006, so not sure they are still in business..Talk to Nate at Betts(800-704-4089)"

That's the annoying thing with Timbrens. You can't just go to a web site, scroll through and order some. The thing is that they aren't really bumpstops. They are overload springs and typically just sold as kits for that. So for a few hundred $$ you get a couple of rubber air springs and some brackets you don't want. The only way I've heard to get just the springs is via Burke spring, ordering over the phone.

They mount with an axial stud. To use a stock bumpstop mount, you probably need some kind of circular plate to spread the compression force to. Possibly some giant washer would work.

EDIT: Wow, I am slow. There were no responses to the original post when I started typing. Then I got distracted...
 
So for mounting, are they threaded so you just screw down into them, or do they somehow have access for a nut from underneath?

People seem to like the way these things work. Seems like a prime thing for ORD or DIY4X, to stock just the springs along with some custom mounting hardware. I could see fronts working with just a round plate of some kind on the stock mount. A cup or something to mount on the spring side might be slick too. Not sure about the rears, but personally I wouldn't mind finding a way to mount something in the stock spot too.

I've gotten spoiled about being able to see pictures of stuff I want and think about it before ordering on-line. Calling on the phone is so old school. :rolleyes:
 
inside of the aeon spring, there is a metal plate with a hole in it for a bolt to go through. The hole I had to make a little bigger to get a socket in there and be able to get it back out, but you put the bolt in from the inside and then attach the spring to a mounting surface of your design...I had those steel plates (I think they are 3/8") drilled and tapped for the bolt to attach to.
 
I had a pair on the front of my sonoma and I called that Burke spring and told them what I was doing with them and they recommended to size I should use. I used on front end with leaf springs and set them so when the spring was flat they were just getting into them but on a hard hit it would allow them to absorb the hit. I had no complaint for a cheap, progressive bump setup.
 
Have them on my blazer. They're pretty good.
