The only solution I've seen is guys drilling a hole through them and then using a very small zip tie to secure it to the spring.

Twist the spring cup so that the notch faces out, towards the wheel. If you don't do this, the spring cup will hit the arm at full compression, and pop the cup off of the shock.

Once you twist them into place, you shouldn't have to keep twisting them back, they will stay put.

I have mine like that, one still came off this weekend. I think it's the bladders sliding up the shock end when the shock rebounds from the vaccuum that occurs when the air is blown out of them quickly when they bottom out.

Try pulling the shock boot up a little further, so there's still slack in it when the shock is fully extended. The shock boot shouldn't be pulled tight when the shock extends.

Also, if you're running a lot of downtravel and not much spring preload, that will cause them to pop off. They need spring pressure to stay in place.

I do that. I am just thinking that when the shocks bottom out it squeezes all the air out and when the shock extends the boot doesn't extend with it and crawls up the shock end. I am going to try balloons instead of the stock boots. The boots are too delicate anyway.

Haha, now that's a phantom problem.

Are you going to use balloons in place of the shock boots, or over the spring?

No kidding! You'd think the spring would be enough to keep them down. If they (Losi) would increase the thickness of the rubber a little bit I think it would fix it. It would make the boots tougher too.

I am going to use them in place of the boots. I test fit one and they are tough to stretch over the lower cap but it gives a better fit at the ball end. We'll see how they hold up. Oh, they come in all kinds of corny colors. I think I'll do pink, it's the new black.

i used the same method as you... coz Losi one is not thick enough.... but my shock piston screw came off from the shaft couple of time... i already cleaned the shaft and used blue thread lock, but still came off....

I use the tko balloon set. Its OK, but the rubber dries out in a day. They are a PITA to put on, but at $5 for a 100 or so, I'd rather use them. The losi ones were easier to put on, but not $5 easier and did not last that much longer. I might try pre-filling the balloons to stretch them out, then installing them. Might make it easier.

My buddy uses the Thunder Tiger boots. They are like an accordian. They are a tad bit thicker and work great. I tried balloons. Forget it!

revhead - Did you clean the screw? Put a dab of loctite on the screw, and then roll the screw on your finger to wipe the excess loctite off. This will leave loctite only in the troughs of the screw threads. Then crank it like heck!

If you haven't, you may want to try a new screw and/or shaft. The threads of one might be bad.

David - You can try gluing the shock bottom to the shock end. It's not uncommon in gas truck to use a dab of glue, enough to hold it on there, but not enough that you can't pop them apart to disassemble the shock.

thanks for the help. I have used ballons for a while now and I would say they work great. Of course I'm the one with the retainer problem though.
