Works Performance Twin Shocks are still very popular for Vintage Mxand other stuff!.
They can be rebuilt as needed from time to time.
The monotube shocks are “emulsion” type mixing the Fluid and Nitrogen in the main chamber tube.
The added Reservoir Types “Divide” the fluid and nitrogen with a bladder so they are a more fade free design.
Single rate springs common when shocks are below 12″, dual rate springs common on shocks 13.5″- 15-3/4″, then triple rate if shocks longer than that.
Dual Rate Springs are common but use a “cross out” which is a tunable and changeable sleeve or series of sleeves under the smaller helper spring (shown above the white color spring) to reduce or enlarge helper spring movement.
Called a “cross out” referring to how they effect the cross out of the helper spring then allowing the shock to work on the main spring sooner or later.
Shown above for various other applications with up to three springs per shock total (one or two helper springs and one main spring).
Works performance have a simple multi “check-ball and spring” design on the inside function instead of valving shims and piston port design.
Works Performance uses a pretty simply “Check Ball” design instead of whats considered true valving and port style valving and main piston.
