Evo 8/9 Beehive Valve Springs by MAPerformance

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. This kit promotes valvetrain stability with even the largest of camshafts and reduces valvetrain mass for the ultimate in high RPM performance!

Can I use these with my DSM? Yes, these will work with Evo 7/8/9 and 1G and 2G DSM's as long as you use the included springs AND retainers!

Why Beehive?

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.

As always! MAP has the right parts!

MAP brand parts saving money but not quality!


Great quality, comparible to GSC Beehives at a fraction of the cost!


The quality and price of these MAP valve springs with titanium retainers are peerless. I don't believe a better spring can be purchased for that price. Certainly none that include titanium retainers. I look forward to using more products from MAP in future projects.

Can't beat the price for the quality!

Bought these when i build my DOHC swap for G4JS which is similar to an evo 8 head. MAP is the best and will always be my first choice when looking for quality.

Great product and quality!

Bought this setup back in June. When I had to build my head Evo 9. Paired with MAP valves and Tomei 270 cams. Great deal and product. Can't beat the quality for the price. Have had nothing but good experiences with MAP to date.
