Twin Cam® CVO Sleeper 110 Kit
Wake up your CVO 110 with our Sleeper 110 Kit!
The 255 cams the factory installed in the 110 have a narrow profile that limits horsepower. Adding a broader profile cam allows the engine to rev more freely but also lowers the dynamic compression ratio and can hurt low end torque. We studied the issue and found that our Red Shift 576 grind, coupled with a small bump in compression (10:1) should boost power across the board – and it did, quite nicely! The Sleeper 110 kit includes forged, +4.2cc pistons, Red Shift 576 cams and Dual-Piston tensioners, Pro-Taper pushrods and E-Z Adjust covers (your choice of chrome or black finish) and necessary gaskets. Result: 28% gain in HP, 17% in torque!

CVO engines are known for oil delivery and lifter issues, so our 417-498 blueprinted cam chest upgrade is a highly recommended option.

This kit uses your factory cylinder cores sent in for modification.
