Redline Performance Kit
for Harley-Davidson
Unleash the full potential of
your 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 – 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.
Why Choose Redline?
Have you ever asked any of
the following questions? What is the best cam, which exhaust is the best
performing, do I need to have a custom tune? If you have this is the kit
for you. We have done the research, completed the testing, and built the
calibrations. We take all of the guesswork out of the equation and give
you a complete system that performs great across the board. There is no
answer to which part is the best, it’s all in how they work together to create
a machine that is reliable and runs with the best. With this kit you can
rest assured you end up with a great build that is bolt on and go.
Do I need to tune with this kit?
That is the beauty of our kits, when you select the IWS
tuner option, it will come with a preloaded map for your 121 motor (other
calibrations are in the works) so there is no need to pay for expensive
calibrations, we’ve done the work for you and it comes with your new kit.
We will need you to send us your VIN number and Year, Make, and Model so we can
preload the maps for your new bolt on kit. If you choose to purchase the cam kit only, then you will be responsible for the tuning required to make sure
everything runs smooth.
Additional information needed?
When purchasing this kit, we will need some additional information about your bike to make sure the tuner is setup properly for your ride. Please follow the link below to submit your vehicle information.
