Default Help with Big Bore Shocks

I have a set of Hobao 17mm shocks that I put on my Truggy. The problem I am having is when I push the car down to compress the shocks, the car doesn't return to normal ride height. The rig stays down a centimeter or two above the ground. I have tried adding more fluid to the shocks, and putting less fluid, I have tried both compressing the shock shaft when screwing on the shock cap and also leaving the shaft fully extended. I even tried different weights of shock oil. Nothing seems to fix this problem. Any help from anyone will be greatly appreciated.

Did you try more pre load?

yeah the springs control the ride height, not the oil

You may also have a bind somewhere. If your hingepins are dirty and binding a bit it will do just what you are describing. You can combat this somewhat with preload.

I appreciate the replys. I had the pre-load adjustment ring set down as far as it can go. My truggy still won't return to normal ride height. When I push it down, my truggy rebounds and the chassis stays barely a centimeter or two above the ground.

I don't think it is my hinge pins but I will double check those to make sure they are clean and not bent.

the shock springs were about a turn too short in the rear and about a half a turn in the front. I put a set of grey Jammin 16mm springs on the shock bodies and that seemed to do the trick. It works great. Now when I push my truggy down, the shocks rebound and my rig comes back to the ride height I set. I'm looking forward to getting my rig out to a track to see how it handles.
