Project RC extra hard on-road clutch spring

Coming from Project RC is an extra hard on-road clutch spring. The item is made of high carbon steel wire and underwent several hardening processes which results in exceptional durability over a long time and thus a reliable clutch setting run after run which is further helped by the machining of the inner portion which improves the seat of the spring. The extra hard spring is usable for both .12 and .21 engines and it is available now.
