Vivid Coil D1+ Flight Attendant Rear Shock Reservoir Upgrade Kit - 

RockShox Vivid Coil D1+ Flight Attendant Rear Shock Reservoir Upgrade Kit converts select non-Flight Attendant RockShox Vivid Coil D1+ rear shocks into a Flight Attendant-capable unit by replacing the reservoir and adding the required electronic module and power components. It’s the cleanest path to modern, system-ready suspension control without replacing the entire shock—while keeping the service essentials in the box for a proper install.

Key reasons this upgrade kit matters

1. Flight Attendant-capable conversion - Updates compatible Vivid Coil D1+ shocks to accept Flight Attendant hardware at the reservoir, positioning the shock for electronic integration.
2. Model-specific compatibility - Designed for RockShox shock models RS-VIVC-UDH-D1 and RS-VIVC-ULT-D1 to ensure correct fit and intended function.
3. Complete reservoir + electronics package - Includes the Flight Attendant Reservoir, Module, and Battery so the key conversion components are matched and ready for installation.
4. Install-focused consumables included - Supplied with a Service Kit, Oil, and Grease to support correct assembly and sealing during the upgrade.
5. Shop-ready tooling support - Includes a 31mm Flat Wrench to help simplify reservoir-related service steps during conversion.
6. Charging solution in the box - Comes with a USB-C Charger (no cord) for battery charging without hunting for a compatible charger.
