By in the cap I dont mean literally inside the cap, there is a chamfer in the bottom that as you tighten the cap down pulls the o-ring in. Sometimes the o-ring can bulge out which means it wont seal.

There should only be enough pressure in the shock for it to rebound 1/4"

yes - but again, to be sure, you slide the oring OVER the body all the way to the recess area, while trying to not "twist" it... not try to put it IN the cap. I've seen many ppl do the latter instead Better safe than sorry

I thought I would update this thread. First of all, I appreciate the additional comments that were made about how to properly build shocks. I can assure all of you that I'm very confident in my OCD shock building techniques after so many years of competitive racing.

At this time neither rear shock is leaking after I switched the caps around on the bodies. Go figure...

Try some teflon tape (for plumbing) on the threads. It has worked for me in the past. Like many, I don't bother filling shelfers. As an aside, I have used a stock motor shim (they're teflon, and for brushed motors) in the o ring stack while assembling the lower seals. My thought was to preload the o rings a bit more to create a better seal on the shaft. It will add stiction to the shock, but I have had some shocks stop leaking, and they seemed to operate fine on the track.

Was going to mention that myself...It works great for shocks period...I always use it and have never had a shock leak...Runner or shelf queen it will work on all applications...
