JUN HIGH LIFT CAM SHAFT 3S-GE / 3S-GTE
Even if it says a camshaft in a word, the profile form is various by the type of a car. Profile form is decided in consideration of the difference of valve motion method etc. (direct type, a locker arm type, strength of moving part, valve size, port and combustion room form). If depending on types of a car, a profile may be restricted by the wall in a head, lifter hole size, locker arm form, etc. At JUN, when developing a high 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.
