EXT Racing Shox Era V2.1 Arma V4 Fork & Shock

ARMA V4 CORE FEATURES

• 3 way adjustable: LSC-HSC-LSR with new 5mm Allen adjustment for HSC for easier tuning
• Unique patent pending PSR technology to avoid harsh top out
• Improved adjustable HBC technology: Effective through last 20% of the stroke with more energy absorption due to new hydrostatic seal design
• 14mm diameter diamond like carbon (DLC) coated shaft. Most advanced engineering coating available for durability and low friction.
• New Spring Thrust Bearing for improved alignment and noise reduction.
• New large volume bladder design with very low reservoir pressure (55psi) to ensure maximum sensitivity.  
• New high viscosity index oil to provide improved consistency over a wide range of operating temperatures. 
• 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
  
• Full custom hydraulic setup that is bike and rider specific for each shock
• Low cavitation
• 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
• Price is for damper only. Springs are available on the product page and a 2nd spring can be purchased at a discounted rate. 
  

*All Shocks are custom built and tuned for specific bike, rider weight and riding style. If you aren't sure about an option, just leave it blank and we'll get in touch if we have questions.

ERA V2.1 FEATURES

Continuing to refine the already best in class, the ERA V2.1 fork uses our HS3, hybrid air spring. Two positive air chambers work with one, high volume self activating negative air chamber. Combined with a high-volume damper cartridge this system offers incredible tuning capability and sets a new level for support in a suspension fork. The Era V2.1 introduces features and upgrades that aims to improve the experience, safety and performance of its' predecessors. 

At its core the Era V2.1 has the same configuration that made Era famous and appreciated: HS3 system, robust anti-creak crown, phenomenal mid stroke support,  excellent stiffness and performance.

The Era V2.1 fork features a magnesium lower design that makes them lighter and load-optimized and it’s made possible by utilizing a specific production process called Thixomolding.

WHAT'S NEW

• Increase in negative chamber volume of HS3 Spring system for improved small bump and top out characteristics. 
• New DU Bushing Material for improved small bump and reduced dynamic friction.
• Expanded damper tune options to dial in the perfect ride for every level and type of rider.
