are these AGX'x blown?
I bought a set of used hyperco springs & kyb agx's on here, took the springs off today to get them powder coated. When I press the struts in they do not rebound at all, maybe a 1/4" at most. It does take a little bit of force to push them in though.

check out the videos, one of the fronts (set at 2) and one of the rears (set at 5)

Just want to know if these are good or not? Im not a suspension expert by any stretch, have only changed struts on a car once.

No good. It should rebound.

yep they are shot

shit.. I pm'd the seller about a refund for the struts, hopefully he will make good.

they are nitrogen charged so they should rebound cant say for sure though. a lot of shocks do not rebound on there own. the purpose of it is to dampen the rebound which will occur due to spring pressure. if you try pulling it up and pushing it down it should have a good amount of resistance and no signs of leaking oil. if they were used with improper springs especially ones that lower the car more than 1inch then you can be sure they are damaged.

some more vids without the boots... I think they might have been keeping the pistons from coming all the way out easily. They still rebound very slowly though. One front & rear extend almost all the way on their own but the others do not. They are hard to push or pull in & out, and 2 of them are very difficult to pull back out.

Put them all too a #1 setting and retest.

Or all the same #setting.

backs were on 5.. fronts were on 2 (one of the fronts is missing the dial though)

for the front, adjust them to full soft at setting number 1, to adjust use a small enough flathead screwdriver push down on the slot and rotate pointer dot to #1

setting on #1 should be easy to push on compression and piston should easily rebound

as you set damper adjustment to hard, compressing the piston will take more force as well as rebound of piston will take longer

Ill redo them all on #1 setting today.. only problem is the dial/pointer are missing from one of the fronts, ill need to use a small needle nose to push down & rotate the pin. Do they lock into place in 90 degree increments without the dial attached?
