SPRING UPGRADE WHEN PURCHASING CYL HEAD

SKU:
$100.00
100 150 $100.00 - $150.00
Unavailable
per item

Most of our heads have .530 springs installed. We can upgrade any of these heads at purchase to a different spring that may be better for your application.

.550 Hi Rev 1.25"

.600 1.4" Dual spring ( for use with our roller cams)

Keep in mind, our heads are already built and sitting on the shelf. We have to disassemble and reassemble the head. You are paying for cost difference in the spring and the labor.
