The Race Tech 40 mm Extended Shock Reservoir Cap, manufacturer part number SMRC 40004 and vendor part number SMRC 40004, is designed for compatible shock reservoirs requiring increased nitrogen capacity. Made from billet aluminum, this replacement cap provides a durable, precision-focused solution for shock performance applications.
Its extended design allows additional nitrogen volume within the reservoir, helping the shock resist performance fade during demanding riding or driving conditions. The recessed Schrader valve supports convenient nitrogen recharging while helping protect the valve from external contact and potential damage.
Designed for fitment with compatible 40 mm shock reservoirs, this Race Tech cap is intended for suspension service, repair, and performance upgrades. Verify the shock reservoir size, cap configuration, and application requirements before installation to ensure proper fitment. Professional installation and nitrogen servicing are recommended when required by the shock manufacturer.
