Redline Performance Kitfor Harley-Davidson

Unleash the full potential ofyour Harley-Davidson with the Redline Performance Kit—a complete,high-performance upgrade engineered for riders who demand uncompromising power,precision, and sound.
This kit detailed below is a bolt on kit, but does require some specialty tools and a high level of technical ability. This is not a kit that we can provide installation support through email or customer phone support. If you do not have the technical expertise to do an install of this nature you will need to bring the kit to a local trained professional who can complete the installation for you.

Kit Includes:

• Redline Cam – Designed for aggressive torque and horsepower gains across the RPM range, delivering explosive acceleration and smooth cruising.
• High-Performance Lifters – Built to withstand extreme conditions, ensuring durability and consistent valve operation. Each Precision Tappet is hand assembled to exacting tolerances and designed for quiet operation and rapid pump up and all are made in the USA.
• S&S Tappet Cuffs - Factory tappet guides are constructed of plastic and are at risk for allowing the tappets to twist under heavy stress. S&S Tappet Cuffs capture the tappets without impacting vertical motion and keeping them perfectly aligned, even in high stress, high RPM situations.
• S&S Adjustable Pushrods –Super strong chromoly steel reduces pushrod flex. Pushrods come with Chrome or Black pushrod covers, O-rings and Cover keepers.
• High-Flow Injectors (121 Models Only) – Maximize fuel delivery for enhanced combustion and throttle response.
• Impact Wiring Solutions Tuner – Custom-mapped for this kit, giving you full performance without the added cost of a dyno tune. This unit will ship separately from the rest of the kit.
• Calibration – As stated above, once we receive your detailed vehicle information we will load the fully calibrated map on the IWS and have it shipped out to you ready to go. If you have any questions or issues regarding the tune, please reach out to IWS for tech support. You will need to have professionally installed the kit and not added components or made modifications to the kit for them to be able to provide remote tuning support.
• Cometic Gasket Set – All necessary gaskets included for a leak-free, professional-grade installation.
• Redline Exhaust System (2-1 or 2-2) – Choose your style: a thunderous 2-1 for peak performance or a classic 2-2 for balanced flow and iconic Harley sound. Both systems are crafted from high quality chrome plated steel and tuned for maximum power and aggressive tone.
