Why We Trust Zipper’s Engine Kits And Why You Should Too
You don’t throw just any parts into a build and call it done. Around here, we don’t cut corners, we cut records. So when it comes to performance upgrades, we stick with the names we trust to deliver, every damn time.
That’s why Zipper’s Performance Products is at the top of our list.
Whether we’re tuning up a daily rider or building a full-blown beast for the strip, Zipper’s engine kits are the go-to. Here’s why we trust ’em and why you should too.
Built for American Muscle
Zipper’s isn’t some overseas off-brand. These kits are designed, machined, and tested for one purpose: to unleash the full potential of American V-Twin engines. Harley power is their playground, and they know how to push it.
They don’t just fit, they perform. Every time.
Engineered with Smarts and Experience
Zipper’s has been in the game for over 40 years. They don’t chase trends. They lead with real engineering and proven dyno results. Their kits are balanced, tuned, and tested to make sure everything from cam to compression works in sync, no guesswork, no mismatched parts.
You get horsepower and longevity. No tradeoffs.
Options for Every Rider
Whether you're chasing quarter-mile times or just want to smoke that guy next to you at the red light, Zipper’s has a build to match your mission.
- Mild to wild stage kits
- High-performance cams, pistons, and heads
- Complete Muscle Kits for serious torque and speed
We’ve installed ’em, tuned ’em, and beat the hell out of ’em, and they keep coming back for more.
Why We Build With Zipper’s
At American Iron Speed-n-Cycle, we don’t gamble with your ride. When a customer comes in asking for more power, we don’t start digging through catalog fluff. We reach for what we know works, and Zipper’s delivers the goods.
Thinking about leveling up your engine? We’ll spec out the right Zipper’s setup for your goals, handle the install, and tune it up until your bike runs like it’s got something to prove.
