I would recommend that you search this board for posts about undercarriage- they generally wear as a set and replacing the tracks (although a likely issue) may not entirely fix your problem. I am assuming that you have properly tensioned the tracks, which can be another cause of derailing.

There are some inspection guides posted so you can measure pin and bushing wear, rail height, inspect rollers, idlers and sprockets, and observe alignment. For instance, you won't want to install new tracks only to have them wear prematurely because your sprockets are worn down.

BTW, you didn't mention what model crawler you own as that will dictate the type of tracks you need (dry or SALT) and availability of them.

Here are a few of the threads that will be useful:

You could also post up pictures of your UC and people can look at it and tell you quite a bit. They found that my recoil springs were broken, causing my track tension to be wrong. Replaced the springs and I've not thrown a track sense.

sounds like you have a 350 (you have never said) 36 is 350 ...39 links is 2010.... if they are standard chains/master pins take a torch and cut off three links (just make sure you do the correct end ..best way to describe that is the male end) edit ..i just looked at your other posts and i see you have a 350 the one chain they sent you is for a 2010 ...same links just three more of them
