shock set-up

front shocks seem to act/respond good, take a load and rebound to desired position.....

rear shocks start out up high, with throttle they lower substanially (torque ???) but then they stay down (a-arms level) and dont rebound, landing from a small (2-3 feet high jump rear skid bottoms and rear end stays low, will not rebound back up....

any suggestions, weak spring rate? need thinner/thicker oil? need better shocks? change oil piston?

what im running....... T-MAXX with INTEGY upper/lower arms, shock mounts, shocks....
