This is a pre-order and will reserve a shock out of the January shipment Charged Cycle Works is receiving from EXT.  Charged Cycle Works has committed to purchasing a HUGE percentage of the total world-wide production run and will have more shocks available than anybody else in the world!

With the help of Suspension Syndicate and EXT we are crazy excited to bring this high end shock to the Surron market.  This shock is custom built and tuned for the Surron and it blows away any shock ever put onto a Surron PERIOD!  The dampening tuned for the weight of the Surron combined with EXT's Hydraulic Bottom Out Circuit makes this shock feel as if you gain additional inches of shock travel, it's incredible and you'll be blown away with its performance.

Engineered with performance and control as primary objectives, the shock structure has seen a redesign in order to be more robust. The Hydraulic Bottom-Out Circuit (HBC) has been enhanced with a wider range of adjustment, in order to prevent bottom-out issues, while allowing riders to use softer spring rates and providing excellent support and end stoke characteristics.

The Arma includes the following features

  • 4 way adjustable: LSC-HSC-LSR-HBC (Hydraulic Bottom-Out Control)
  • High flow 29 mm main piston
  • 24 mm valve piston
  • 14 mm shaft (50% larger than most other coils on market to help deal with large side loading events)
  • Engineered rebound circuit to separate bump and rebound oil flow – Ultra low-friction coating
  • User adjustable HBC technology
  • Very low reservoir pressure for maximum sensitivity  and low cavitation(55 PSI)
  • Full custom hydraulic setup that is bike and rider specific for each shock
  • Very low hysteresis for high dynamic response
  • High turbulent flow for progressive dampening and mid stroke support
  • Low friction seal
  • Thinner bottom-out bumper and debris clearing washer
  • New low profile rebound knob for easy spring swap
  • Included with 1 light weight spring available in 400lb, 450lb, or 500lbs (Lower options may be available upon request)
  • Comes with Sur Ron specific mounting hardware for easy bolt in instillation. 

*This is a special edition shock that will be built in limited runs. Delivery time is expected to be January 2022.

Spring Rate Suggestions

Charged Cycle Works will consult with you how you would like your shock to be setup, depending on your preferences you may want a softer than suggested spring.  The advanced tuning available on this shock allows a high degree of adjustment and tuning for the rider to dial in exactly how you want this shock to perform, from ultra-plush to ultra-stiff to anything in-between.
