Yes I'd love to share my setup. So I beleive and I could be wrong here... that these shocks should not have any oil in them except for a quick once over on the shaft. Well at least mine don't and they work fantastic. So the way I have mine set up...they come with three different springs, soft, medium and hard. I use the hard ones in the front because of the weight of the 3S 5000 MaH battery and receiver, speed controller, CC BEC. The rear shocks use the medium springs. Just put some oil on the shaft and compress up and down three times. The shafts only need to be coated on the outside so it has a thin layer. This thin layer of oil will simply carry up into the shock one compressed. That's all it needs. The inside of the shocks only contain the spring and no oil. When the car sits for a long time, compress the shocks up and down 4 or five times and it will be smooth again. Only use 1 seal or the way they came. If after you loosen up the shock by pressing up and down it's still rides rough, just apply a small amount of oil to the outside of the shock shaft and press up and down again. This just means that the shock got possibly dirty or ran through some water the last time you took it out. Another trick is to loosen or unscrew the shock cap just a little to get it to slide better (allows it to breath some as these are really air shocks w/ springs). That's about it. But Yes, these shocks would definitely leak if you put oil in them as the seals are not meant to hold oil inside of them. These shocks are meant to be scale shocks and hence the springs on the inside do their job good without oil. The thick pistons make these these shocks look great on a scaler and to me they perform really great. I've been using them for 6 months and they compress very well and toll side to side just as good as the stock ones that came with the truck. They just look better IMO. If looking for oure performance they will not be better than real oil filled shocks. But to me, they are really close and the maintenance is really simple on these shocks just because there's just not much to them. It's just a spring on the inside. Others on this forum have had major issues with these shocks. I have had the best experience with them and wold but them again. I have had no regrets so if you like the looks give them another shot! They are only $40 (for 4 of them). You can always sell them on CL for $30 because they are a good looking shock.
