At Jun, when developing a high performance camshaft, the detailed data for each type of a car is taken, development is furthered simultaneously with a valve spring and retainer, and the optimal profile is determined. This ensures that Jun create some of the highest quality camshafts available on the market.

We recommend up rating your valve springs and retainers at the same time as switching to these cams.

Due to the aggressive ramp angle on this cam, it is designed to be run on sold lifters. Please see related parts for details.
