Brian I saw those and even though they look really nice, they are to short for the LST2 shocks I'm using. IMO, the only way to make them work properly with the LST shock cartridges is to do exactly what I plan to do which is to open the cartridge, enlarge the holes for the shaft and replace the O rings with ones with a thinner cross or thickness. Unless the Hot racing reservoir shocks use a cartridge that fit the LST2 shock body. I'm not sure. Maybe they could work but I wouldn't get the full extension that I have with the stock length of the shock shafts, it is something like 87 mm long if I remember correctly. Thanks for searching I appreciate it.
On an another note, I gave up on my E-Revo to go with the LST because I find it is tougher and easier to work on. But there are things on the E-Revo that I really liked. The tranny for one which I installed on the LST but also the Traxxas VDPs (Variable Damping Pistons) in the shocks. So I am going to try it on the LST with these little valves I made out of a piece of thin polycarbonate from some packaging that was lying around in the recycling bin. I know Hot racing makes pistons with tapered holes which are supposed to have the same effect, I'm just trying to do it on the cheap.
The valves block 10 of the 24 holes of the piston on compression which should give better, stronger damping, and the valves bend slightly to let the oil pass through all 24 holes of the piston on the rebound.
I made a second 5 mm shock shaft and ordered the Viton O rings I linked before. When all the parts get here, I can finally try out those shafts on the front end with the VDPs front and rear.
