Twin Cam® ’07-’17 Sleeper 107 Kit

The Sleeper 107 kit is an easy and affordable upgrade for 2007-up 96 or 103” Twin Cam® engines. Your cylinders are precision-bored from 3.750” (96”) or 3.875” (103”) to 3.937” to boost displacement to 107”, while your stock cams are replaced with our Red Shift 528 grind. The forged flat-top pistons used boost compression to 10.25:1, while the 528 cams yield impressive power and torque gains across the entire RPM range with stock heads. Gain even more power with (1) our optional Stage 1 headwork and (2) improve longevity with critical oil system blueprinting by adding our cam chest upgrade that includes our billet cam plate, dual-piston cam tensioners, full-compliment cam bearings and Feuling lifters.

With power peaking at 5,000 RPM, this kit is a great choice for the rider who rarely pegs the throttle to red line, but rather enjoys the super-strong pull of low and mid-range torque! This kit uses your factory cylinder cores sent in for modification. An exchange may be possible once your cores are cleaned, inspected and qualified for exchange.
