Street Racer Shock for Harley-Davidson Nightster
 
Win Races. Outrun Anyone. Dominate the Streets.
Unlock the full performance potential of your Harley-Davidson Nightster with the American Suspension Street Racer Shock. Engineered for aggressive riding, high-speed cornering, and real-world performance, this is not a comfort shock pretending to be sporty — it’s a true performance upgrade built to keep you out front.
 
World-Champion Proven Performance
The Street Racer Shock represents the pinnacle of Harley performance suspension. Designed using decades of race-winning experience, every shock is precision-built to deliver maximum traction, stability, and control — whether you’re carving canyons, pushing limits on the street, or riding hard mile after mile.
 
Hand-Built in the USA — Built for You
Every Street Racer shock is hand-built in the USA and custom-tuned to your specific bike and riding style. When you order, we tailor the valving and setup based on your weight, riding preferences, and performance goals.
This isn’t a generic, one-size-fits-all shock — it’s purpose-built to fit your Nightster like a glove.
 
Wide Adjustability for Total Control
Dial in your suspension exactly the way you want it:
Preload Adjustment – Set proper sag for optimal balance and traction
64 Rebound Adjustment Positions – Fine-tune ride feel from aggressive to compliant
With a few quick adjustments, transform your Nightster from a sharp canyon carver to a composed street machine — all without compromise.
 
Fully Rebuildable & Track-Serviceable
Built for serious riders, the Street Racer shock is completely rebuildable and serviceable. Designed to be tuned, refreshed, and optimized over time, it delivers long-term performance instead of disposable suspension.
 
Sophisticated Valving System
Our advanced valving system is the result of decades spent racing and tuning at the highest levels. We know that no two riders ride the same — and your suspension shouldn’t either.
This level of customization exists because performance isn’t generic, and neither are you.
 
The Philosophy Behind Street Racer
Over 30 years ago, while tuning race bikes, we learned a critical lesson: even elite riders on identical machines required different suspension setups. That insight became the foundation of American Suspension — personalization over mass production.
Your riding style is unique. Your suspension should be too.
 
Ride Free. Ride Your Way.
Don’t let big corporations dictate how your bike should feel. The Street Racer shock gives you the freedom to tune your Nightster exactly the way you want it — sharper, faster, more controlled.
When you’re pushing hard, leaning deep, and powering out of corners, American Suspension is there with you, keeping your tires planted and your confidence high.
