EXT Arma MX Shock for Surron & Talaria

Spring Weight (Use chart in description as reference): 400
Primary Use: Dirt (Trail/Off Road Tune)
Sale price$1,150.00


This EXT Arma MX shock is a direct bolt on replacement for the Sur Ron Light Bee X and Talaria Sting. No additional Hardware is needed.

We have tested a variety of suspension setups for the Surron Lightbee X and Talaria Sting and we find the EXT Arma to be the best shock to upgrade your Surron or Talaria.

The EXT Ferro Fork is a great option to pair with the EXT Arma, allowing for a premium suspension combination while retaining stock geometry and weight of the Surron and Talaria.

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 MX 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, 500lb, 550lb or 600lbs (Lower options may be available upon request)
  • Comes with Sur Ron specific mounting hardware for easy bolt in instillation.
