3 different design pistons for focused application:  We use in-house designed 48mm and 42mm large diameter aluminum pistons for better performance and easy tuning.  Our pistons are fully CNC machined to exacting tolerances and recognizing that there is no one size fits all, we have designed 3 different types of pistons for use in street, tuned or race applications.

Cylinder Assemblies:  To ensure uniform strength and accuracy of alignment throughout the vertical place for our cylinder assemblies, all cylinder top caps and cylinder case bottom caps are screwed on and locked in place before welding.  This removes the problem of deviation of the alignment between body and cap during welding, providing a truly straight assembly with uniform high rigidity, thus reducing uneven wear on both the hard chrome and the damper case slide bearings and rod slide bearings.

Special thick hard chrome on cylinder bodies:  All cylinder bodies are treated with a thicker than usual layer of hard chrome with the threaded damper case made from hard stainless steel to improve corrosion resistance and ensure longevity in use.

Rod Size and finishing:  All rods are 16mm in diameter and treated with thick hard chrome to improve durability

Damper shims:  12 different size shims are used in our dampers allowing for fine tuning and giving our users a range of adjustability and tuning breadth unheard of in old model JIC and competitor manufacturer products.

Pillow Ball Upper Mounts:  Most S series kits come with front upper mounts fitted with pillow ball bearings.  Kits for Macpherson Strut applications come with camber and caster adjustment systems built in.  All upper mounts are 40% thicker than before for added strength.

Lower Brackets:  All lower brackets are machined from hard aluminum and are height adjustable.  Macpherson strut application lower brackets are designed for optimal strength to weight ratio by utilizing a H-beam design.

Oil:  All our S kits use a special blend of synthetic oil for better and more stable performance with optimized viscous stability of long and hard use.

Maintenance support and parts availability:  All S kit customers will have access via our partners or ourselves to maintenance support and spare parts for rebuilding or customization.
