Hi all. I've recently assembled my brand new shocks that come with my Savage SS kit. The shocks don't spring back up, they go down and stay saggy. Anyone got any ideas?

This may be a REALLY stupid question...but do you have the springs on them?

have you put oil in them yet? weight?

buddy92

Haha, Yes.
Yep they are fully assembled as per the book, and I believe the oil supplied with the SS kit is 80wt.

They spring back about 2cm, the back of the car is still practically on the ground.

Not sure what's happened!

Does the shaft and piston seem to be smooth even before oil? Did you bleed all the air out? Sorry if asking dumb questions back kind of hard to visualize! Maybe video?

I checked and it keeps loosing all its oil out the little "air vent" hole I'm assuming it is? A pin sized hole at the top mounting cap, everytime it compresses, oil comes out. Fill it back up and it's fine again. How do I stop that? I can take a video tomorrow ( it's 1am now)

It's actually pumping the whole lot of oil out the hole, every drop :S

What vehicle sometimes there is a small screw to fill the hole. Or you have your o rings in the top in wrong place. The hole is used to bleed the air out of the shocks. Maybe Google shock building for your type of car shock. There is also lots of videos on all types of shocks.

Did you remember that there is an oring that fits into the top of the cap?

As for ride height, use the adjusters on the shock body, twist them down.

I think its the oil weight you chose, 80wt is pretty thick for savage shocks. You may want to try something thinner. And before you do that take the oil out and make sure the piston moves up and down in the body without binding

Thanks for the suggestions everyone, I'll check it all and see how I go.

the weight of the oil should have little affect when the motion of the piston is so slow, the oil has enough time before the piston moves through an up or down stroke to move through the holes of the piston as the piston is moving. (thicker oil moves slower through the holes causing a slower stroke, and you would have to have the resistance from the oil going through the holes be greater that the pressure from the spring to not come up.)

Unless you were to put something like high wt diff oil in it shouldn't make a difference.

If the shocks don't feel smooth, take the pistons out and clip any flashing from the sides. (Upbasher's idea)

80 wt...are you sure that's not diff oil? 80wt to me is super high for a off road vehicle.
springs control ride height. you need to pre-load them more. that means if you have threaded shocks turn the collar down more or if they have clips put more clips in.
as for the oil 30-40wt should be good for a truck/buggy. you want the suspension to absorb bumps not lock up hitting them.

it is quite high, especially in a smaller vehicle.
