Team Losi Racing Threaded Rear Outer Hinge Pin (TLR 22)

This part should have come with the kit in the first place! I hate e clips.
Just remember to not get carried away and over tighten these. If you over tighten you will loose the free movement of the rear arms, not to mention that if they are too tight, they are more likely to loosen and come undone o-O... Strange but true.

Great product overall. Personally I would use red thread locker one one nut and then maybe blue on the other side for when you do need to get it apart. They can seem at times to be a hair short and not get as much engagement and holding power in the nylon inserts in the nuts. I personally switched to a different and shorter nylock nut, or can use crimped nuts instead of nylocks. In any case, what can be a potential problem can easily be remedied with a little locktite, which should be used on more critical parts like this anyway where there are forces trying to move and spin them as they will have more potential to come loose. Good upgrade to get, and just need to prevent what could be a potential problem before it happens.

These didn't work well for me. In order to get the threads to engage the nylock, I had to over tighten the nuts on each end. Afterwards, both sides had a nut that came loose during a race. This occurred after 5 to 6 races. Over tightening will prohibit free movement of the hubs causing a ball-stud to break-off in the hub. Just know this before going this route with your outer hinge-pins.

Who ever thought that e-clips were a good idea anyway?? A must have replacement part. Never struggle with e-clips again!
