Sample Shock IMG_3045


Divided Internal floating piston shocks need the “cylinder head”(that’s the top aluminum shock casting at body end top) that usually heated off the body while holding in an exact aluminum fixture in a 20 ton press.


Then setting the floating piston depth in (mm) after vacuum building the shock on a machine, then loctite and torque cylinder head to manufacturers specs.




You need a spring press to remove most springs, especially the shocks with a preloader.




Even hydraulic remote spring preloaders are Vacuum machined to 100% , then they should be load test for full range to manufacturers spec shown below with appropriate fixtures.



Load tested and  Maintaining Factory Spec  movement then you know that’s how they should be.






The Only way to get 100% of the air from a shock is to do them on these Factory Vacuum Machines, to do most shocks with the correct fittings allow around $10k US Dollars to purchase.

This Digital gauge we recommend using in conjunction with the above needle gauge so you can have


2 separate gauges attached at once to the shock to double check your preset nitrogen pressure.
