103 Springs with retainers


SKU: 07-s-009 Category:


This is the high RPM version of our 24v 103# spring. Triple Shot peened and stress relieved. If you are running over 4,500 rpm and have a cam with over .320″ lobe lift, then I suggest these springs with light retainers. Titanium for cams with over .370″ lift.

As a precautionary measure, please inspect titanium retainers after every season for wear.
