Aria V2 Enduro Trunnion Air Rear Shock

EXT Aria V2 Enduro Trunnion Air Rear Shock is a highly tunable enduro air shock built for riders who want coil-like traction and composure without giving up the packaging and adjustability advantages of an air spring. Its proprietary AS3 dual-positive air spring and large self-activating negative chamber focus on small-bump sensitivity and mid-stroke support, while its damper architecture targets consistent control on long, fast descents.

Dial-in advantages for aggressive trail and enduro riding

1. AS3 Dual-Positive Air Spring - Uses a dual-positive layout designed to deliver a coil-sprung feel, improving grip and calmness when the trail gets rough.
2. +/++ Dual Air Valves - Two separate positive-chamber valves (low/high) let the rider fine-tune the air spring curve for better support, traction, or progression depending on terrain and riding style.
3. Large Self-Activating Negative Chamber - Increases initial suppleness for improved small-bump compliance and traction, especially valuable on roots, chatter, and off-camber braking zones.
4. LOK 2.0 Two-Way Lockout with Blow-Off - A tunable lockout system improves pedaling efficiency across varying surfaces, with a blow-off valve to help protect control if the lever is left engaged when impacts appear.
5. 28mm Main Piston with Super Finish - A large-diameter hydraulic main piston with Super Finish surface treatment supports consistent damping performance and smooth action under load.
6. Adjustable HBC Hydraulic Bottom-Out - The Hydraulic Bottom-Out Circuit (HBC) adds tunable end-stroke control to reduce harsh bottom-outs while keeping the shock active through big compressions.
