Description
Per your request – an adjustable wing tree for the JRX D1 Junior Sprint. It makes changing wing pitch dramatically easier: no wrenches required.
Wing pitch is one of the fastest adjustments available on a Jr. Sprint and one of the most under-used, precisely because on most cars it means tools and time between heats. Remove that friction and people actually adjust it when the track changes.
Fits JRX D1 Junior Sprint chassis. Built by Driven Performance in Fresno, CA at the request of racers running our cars.
