Super Shox SR1 Premier Series Rear Shocks
Harley-Davidson Road Glide (2002–Present)
Super Shox SR1 rear shocks are hand-built in the USA and configured to a rider-specific baseline based on rider weight and typical load — so your suspension shows up built around how you actually ride, not a generic factory rider.
Dreaded Iron Moto is an authorized U.S. Super Shox retailer, offering the same pricing as buying direct from the manufacturer, with added rider guidance and support.
SR1 = The Best First Suspension Upgrade (Comfort + Confidence)
SR1 is designed for riders who want a major upgrade over stock with a focus on:
-
smooth comfort on rough roads
-
stability and predictability at speed
-
reduced fatigue on long days
-
simple setup you don’t have to overthink
If you’ve never upgraded suspension before, SR1 is the model most riders should start with — because it delivers the biggest real-world improvement with the simplest ownership experience.
Direct Bolt-On Installation (No Hardware / No Modifications)
SR1 is a direct bolt-on replacement for compatible Harley-Davidson models.
-
No relocation brackets required
-
No cutting or permanent modifications
-
Straightforward installation
Professional installation is recommended to ensure correct setup and best performance.
What Most Riders Notice First
SR1 improves the parts of touring that people don’t realize are optional until they ride better suspension:
-
expansion joints and small bumps stop beating you up
-
less fatigue (especially upper back + tailbone)
-
the rear end stays composed instead of bouncing or kicking
-
smoother feel on imperfect pavement
-
more confidence in corners and highway sweepers
A lot of riders don’t realize how much stock suspension is holding the bike back until they experience a properly set up shock.
Spherical Bearing Mount (Performance Difference)
Super Shox uses a spherical bearing mount, allowing the shock to twist naturally as you lean the bike. That improves shock movement and traction under real riding conditions — a noticeable upgrade over stock rubber-bushing style mounts.
Tool-Free Adjustability (Built for Real Riders)
SR1 includes tool-free preload adjustment, making it easy to dial for:
-
solo riding
-
solo + gear
-
occasional passenger use
Every set includes a setup chart so you can start in the correct baseline without guessing.
SR1 is Ideal For
-
Daily riding and commuting
-
Weekend and long-distance touring
-
Riders upgrading suspension for the first time
-
Solo or lightly loaded setups
-
Riders who want comfort + stability without complicated tuning
Ride Height & Shock Length
Super Shox shock lengths are listed based on real-world installed ride height once properly set up, not raw eye-to-eye measurements.
Because each set is built to rider weight and load, uninstalled shocks may measure slightly longer. Once installed and adjusted to the recommended baseline, the bike settles into its intended ride height with proper sag and suspension travel.
