This Zipper’s 110″ Kit is for the owners of Screamin’ Eagle® CVO bikes or customers with a factory 110” Stage I kit. The 110” engine really comes alive with this top end and cam kit. Torque and horsepower is increased across the RPM range. Where the stock engine starts to level out at just over 4,500 RPM, the Muscle 110” kit kicks into overdrive and raises horsepower by 45%! Peak horsepower climbs from the mid-80’s to the high-120’s with torque over 100 ft/lbs from 2,500 through 6,500 RPM, breaking the 120 ft/lb barrier along the way. Power builds smoothly and effortlessly, without sacrificing low end torque adding needed Muscle to the Bird!
Your 110 heads are carefully ported to increase velocity and are assembled with Zipper’s Step-Lock guides, flow-enhancing valves and performance springs. After truing the cylinder head gasket surfaces, compression is raised by precisely fitting their proprietary 10.5:1 forged pistons to your 110 cylinders using torques plates. Red Shift cams, Pro-Taper pushrods and Dual Piston cam chain tensioners are included with Axtell’s oil pressure bypass valve for increased life and valve train control. A pre-mapped ThunderMax® with Wave Tune AutoTune is included, allowing fast, dyno-free set-up without engine tune worries. High flow injectors are included with this kit (kit requires the separate purchase of a H-D® 58mm Screamin’ Eagle® TBW throttle body). For more information, contact Zipper’s Performance Products.
