    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.

    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.

    Included Components

    This particular kit includes a complete set of 16 valve springs only as they were designed to utilize the factory Evolution 8 & 9 spring seats and retainers. If valvetrain stability is your primary concern, replacing your factory springs with these alone is more than sufficient for the majority of our customers. However, a complete kit with titanium retainers at an additional cost would further reduce valvetrain mass if that is the intent.

    Ultimate Duty Series

    Seat @ 1.50" = 85lbs
    .473" = 202lbs
    Max Recommended Lift: 12mm

    Important Note: These springs will work ONLY with the stock Evo 8/9 retainers or MAP Titanium Retainers. Other stock 4G63 retainers (including Evo 7) are NOT compatible with these springs. If you need a set of springs with retainers, please purchase our Beehive Spring Kit with Titanium Retainers here.
