available for the high lift, high rpm applications. The new single
valve spring delivers 15% more pressure across the board than the
factory part. Also, with a coil bind of 0.820", the Crower spring
allows for more cam lift than factory springs will allow. Crower
titanium retainers weigh in at 7 grams vs. stock steel at 14.5 grams.
