When do I need to rebuild them?

[chrisexv6]

I was just wondering if there is a good way to determine if my shocks need rebuilding.

I've heard of the 1/4 rebound method, but was wondering if there was something more precise reason being I want to put shock socks on, and figured Id rebuild them at the same time if its necessary, to save myself the extra trouble.

Also, if I do need to rebuild them, anyone know where to get the rebuild kits for Progressive shocks?

Thanks!!!

Rebuilding shocks is either a requirement or a matter of preference. In the case you are describing, I'd go ahead and give them a rebuild.

As for the rebuild kits, they usually consist of several o-rings and a couple of shock cap diaphragms. Most on-line hobby shops and your LHS should have them hanging around.

As for the science behind determining when to rebuild your shocks, the rebound method is probably the best way to determine if you need to rebuild them. If you compress the shock and it goes smoothly (as in it feels like the piston is moving through oil) and then suddenly jolts to the fully compressed end, then you should think about rebuilding them because you are low on oil. Beyond that, good rebound action without the spring on is a sign that the shock still has life in it.

I usually look for dirt buildup where the shaft enters the body. If your running in dry dirt and the dirt cakes up, this means oil is leaking out of the body onto the shaft due to worn o-rings.

i dont now if u have heard of Shock Sox but they work great. they cover the shock shaft to keep dirt and stuff off the shaft. they are suppose to keep u from rebuilding often. they have worked really good for me. for $5 they are worth it.

Maxx Trooper, I recommend reading the entire thread and original post. He has heard of shock socks and is looking to install them. If your comment was directed at Eddie, believe me he knows about them. He just likes to use socks for other purposes.

I have to agree with Sky on this one. I guess I have been lucky on my t-maxx because after almost 2 years with big bores on it I have inspected them every couple of months but they have not needed rebuilding they work fine and still bash with the best of them.
