Evo 8/9 Beehive Valve Springs
MAP beehive valve springs are engineered to exacting tolerances utilizing only the finest materials by an ISO certified valve spring manufacturer. Designed with performance in mind these valve springs are ideal for camshafts that feature more aggressive lift and duration profiles.
MAP beehive valve springs utilize ovate shaped wire that more effectively distributes stress over the entire wire area in comparison to a typical round wire spring. The thinner cross-section wire also allows for more coil bind clearance to accommodate higher lift camshafts. Retainer end mass is reduced allowing for improved performance in high RPM applications and coil surging is dramatically reduced providing improved valve control and fatigue life of the spring itself.
This particular kit includes a complete set of 16 valve springs and MAP titanium retainers. This kit promotes valvetrain stability with even the largest of camshafts and reduces valvetrain mass for the ultimate in high RPM performance!
