JUN manufactures aftermarket performance parts and engines for Japanese cars. They make parts such as piston kits, stroker kits, valves and Plenums. The parts they make are designed to upgrade the performance over standard OEM parts.

When valve speed increases by high rotation-ization of engine, 'valve bounce' may occur by the factory valve springs. Moreover, since inherent pitch is low, 'Surging' may occur in a high rotation region. In JUN, the valve spring with which the load optimal at the time of a set and a valve lift is acquired was manufactured. Even when the amount of valve lifts increases by using a high cam, since the adhesion margin is secured enough, the JUN valve springs does not have degradation and its durability is also improving.
