Harley Cams & Parts — Unlock Your Engine’s True Performance Potential

Welcome to our Harley Cams & Parts collection — the go-to source for high-quality camshafts, lifters, pushrods, timing components, and performance hardware designed to enhance power, torque, and overall engine response on your Harley-Davidson. Whether you ride a Harley Softail, Touring, Dyna or Sportster, upgrading your cam system can dramatically change how your engine delivers power and performs under load.

Why Upgrading Your Camshaft & Related Components Matters

A camshaft controls when and how the valves open and close — dictating air-fuel flow, combustion efficiency, torque curve, and overall engine character. Upgrading cams and associated parts gives you:

  • More low-end torque or high-end horsepower, depending on cam selected and exhaust pairing

  • Stronger throttle response, smoother acceleration and improved overall engine feel

  • Better performance when combined with intake, exhaust, and fueling upgrades

  • Potential to support larger displacement or “big-bore” engine builds

  • Improved engine breathing, efficiency, and combustion under load

For riders seeking to build a powerful, responsive ride instead of stock behavior, cam upgrades are a foundational step.

What You’ll Find in Our Camshafts & Performance Parts Collection

Our collection includes a wide array of components tailored for various build types and performance goals:

  • Performance Camshafts — from mild upgrades to full race-ready profiles

  • Factory-spec Replacement Cams — for stock restorations and maintenance

  • Lifters, Pushrods & Tappets — to match cam profiles and ensure smooth valve operation

  • Cam Timing Components & Gears — for precision timing and reliable operation

  • Valve Springs & Retainers — to support aggressive cam profiles or high-RPM builds

  • Gasket & Seal Kits — essential for proper installation and leak-free operation

  • Cam Boxes, Covers, and Related Hardware — for full cam kit installations or rebuilds

We support a broad range of Harley engine platforms — including Evolution, Twin-Cam, Milwaukee-Eight, Sportster, custom builds, and big-bore conversions.

How to Choose the Right Cam & Parts for Your Harley

1. Determine Your Performance Goals

  • Mild upgrades — for improved throttle response and torque under normal riding

  • Performance builds — for increased top-end power, especially when paired with intake and exhaust upgrades

  • Heavy load / touring / custom builds — for stronger torque and improved mid-range performance

2. Match to Supporting Modifications

Upgrading the cam without adjusting intake, exhaust, or fueling often leads to poor performance. For best results, plan to run compatible air intake, exhaust, and fuel management with your cam setup.

3. Use High-Quality Supporting Parts

Ensure lifters, pushrods, springs, and timing components match the cam profile — as these are critical for longevity and smooth operation.

4. Know Your Engine Platform & Year

Harley-Davidson engines vary widely — confirm the compatibility of cam specs (duration, lift, timing) with your engine’s displacement, cylinder heads, and other internals.

Benefits of a Well-Matched Cam Upgrade

  • Enhanced throttle response and smoother acceleration

  • Realistic power gains when combined with intake, exhaust, and fuel tuning

  • A more robust, street-ready engine feel — especially under load or heavy riding

  • Flexibility for future power upgrades (big bore, higher compression, performance tuning)

Frequently Asked Questions

Will a cam alone make my Harley much faster?
A cam alone changes how the engine breathes and can enhance throttle response and torque. However, to realize full gains, pairing with intake, exhaust, and proper fueling is recommended.

Is upgrading cams safe for daily riding?
Yes — if you select a cam designed for street/riding conditions and maintain compatible tuning and fuel setup, a cam upgrade can improve rideability and performance without compromising reliability.

Do I need new lifters and pushrods when upgrading cams?
Often — especially if moving to a more aggressive cam profile. Proper lifters and pushrods ensure smooth valve operation, prevent wear, and support increased lift or timing changes.

Will cam upgrades affect maintenance intervals?
Possibly — more aggressive cams may require more frequent inspection of valve train components, especially if performance tuning is involved.
