Vecta Trunnion Coil Rear Shock

The EXT Vecta Trunnion Coil Rear Shock is a coil-sprung rear shock built for riders who want consistent damping control, high traction, and predictable support across long descents and repeated impacts. Its trunnion mount format targets modern frames looking for compact packaging and precise suspension response, with tuning range that supports both efficient pedaling and confident descending.

Tuning and ride-feel highlights

1. LOK 2.0 tunable lockout - Adds a 2-way, rider-tunable platform for improved pedaling efficiency on mixed terrain, with a blow-off valve to protect control when impacts arrive unexpectedly.
2. HBC bottom-out circuit - Increases damping force in the last 20% of travel to resist harsh bottom-outs while preserving coil sensitivity earlier in the stroke; can help riders run a lower spring rate for compliance without giving up end-stroke support.
3. 3-way external adjustment - Independent high-speed compression, low-speed compression, and rebound tuning for dialing in chassis support, traction, and recovery speed to match terrain and riding style.
4. Large-volume bladder reservoir (55 psi max) - Designed for stable performance and consistent damping feel under sustained heat and repeated hits.
5. Negative spring top-out control - Helps eliminate harsh top-out “knock” for a quieter, more refined feel at full extension.
6. Durability-focused internals - A 14mm CrMo damper shaft supports wear resistance, while spring thrust bearings help keep the coil aligned and reduce spring noise.

Notes: Coil spring and mounting hardware sold separately. Listed weight is 477g for a 210×55mm shock without spring.
