Built to run modern big bore springs on classic shocks, and designed by an active racer. Ultra-lightweight petal-style design to keep sprung mass and CG as low as possible, something you don’t see on other big bore adapters. Fits Team Asso buggies and trucks (RC10, B2, T2, and more). Works with threaded and classic shock bodies. Currently 12mm only. If there’s interest in a 13mm version, leave a comment or send a message.
