Beehive Valve Springs
Beehive valve springs have been known in the industry as having a lower mass at the retainer end thus allowing for better valve control. This is only partially the reason for the better valve control. Beehive valve springs are unique when it comes to coil spacing, rate control, and also using a MA wire cross section. Beehive springs benefit from utilizing ovate shaped wire. This wire more effectively distributes the stress over the entire wire area allowing for more complexity within the spring improving the fatigue life of the spring. Contact Crower with your inquiries.

Stainless Steel Shaft Rockers
For those of you that feel most confident running a steel based valve train, we offer you the Crower collection of shaft mounted stainless steel rocker arms. Each and every configuration has been religiously scrutinized to offer extreme rigidity and accuracy while optimizing moment of inertia phenomena condition. Crower engineers made ease of installation and maintenance a top priority so you’ll never waste a moment when time is critical at the track. Our stainless steel shaft rocker systems are a perennial favorite of dirt late models and marine endurance competitors. Sustained high temperature has little affect on the strength properties of stainless steel so components made from this material should have a longer life expectancy than similar components made from aluminum.
