General specs:

• Mono-Tube Shock (Rebuildable) design
• 30 way adjustable damping control (compression/ rebound) via knurled knob on top of shock.
• Optional Pillowball or rubber upper mounts. Rubber mounts offer a lower noise ride while Pillowball offer precision handling.
• Separate ride height adjustment means that you do not need to change spring preload to adjust vehicle ride height.
• Springs rates are specified below but can be customer specified as well. Large steps in spring rate will also include the proper revalving.

Technical Specs:

• 46mm Pistons over 53mm shock housings providing a large range of damping force capabilites.
• Special spring-steel valves which outperforms other stainless steels and offers prolonged valve life.
• Patented concave lower locking ring to prevent unseating
• Springs constructed of SAE9254 High Strength steel that is compression tested over 500,000 with less than 5% deformation.
• Pistons are high polished steel to lengthen oil seal life which means no leaking and longer seal life.
• High pressure inner rod guide seals ensure a perfect fitment resulting in consistent fade resistant damping and long seal life.
• 2-Step coating process utilizing nickel and chromium plating to prevent corrosion.
• Newly developed lubricant oil in all shock cartridges minimizes aeration/foaming and cavitation.

Custom spring rates are available. You can request custom spring rates by entering the rates you want in the special instructions box after clicking add to cart. Spring rates up to 18K are available in BC Springs. Rates higher then 18K will require Swift spring upgrade.
