Super Shox SR1 Premier 14.5" Rear Shocks | Tri Glide 2017-2025

Super Shox SR1 Premier Rear Shocks

2017–2025 Harley-Davidson Tri Glide Ultra

14.5-Inch Long-Travel Trike Suspension — Built Around Your Setup

Super Shox SR1 Premier rear shocks are engineered specifically for Harley-Davidson three-wheel models. Each set is configured around your rider weight, passenger weight and typical touring load—not pulled from a shelf with a generic setup.

For Tri Glide riders, that means improved suspension control where it matters most: rough pavement, expansion joints, corners, inclines and long days carrying real touring weight.

Built Specifically for Tri Glide Touring

A Harley-Davidson Tri Glide carries substantial rear weight even before adding a passenger, loaded Tour-Pak or additional gear. Its suspension must control that weight while keeping the ride comfortable, planted and predictable.

Super Shox SR1 Premier Tri Glide shocks are designed to provide:

• Smoother response over rough pavement
• Reduced harshness through bumps and expansion joints
• Better stability and control under load
• Less side-to-side rocking on uneven roads
• Greater confidence through corners and inclines
• Improved comfort for both rider and passenger

SR1 remains the correct Super Shox platform whether you ride your Tri Glide solo, two-up or fully loaded for a long trip.

Why Super Shox Recommends 14.5-Inch Shocks

Super Shox recommends the 14.5-inch SR1 setup for most Tri Glide riders. Its additional usable suspension travel gives the rear suspension more room to absorb bumps and control the weight of the trike.

Benefits include:

• Increased suspension travel
• Better bump absorption
• Improved stability and handling
• Better muffler clearance on inclines
• More controlled performance under passenger and luggage load

The resulting ride-height change varies by model year, existing suspension and configured preload. The 14.5-inch setup can raise the rear of the trike while providing additional travel and clearance.

These shocks install using the factory shock mounting locations. Do not combine the 14.5-inch shocks with a separate trike lift kit—the longer shocks replace the need for one.

Built Around Your Rider and Load

Every SR1 set is configured using your actual riding information:

• Rider weight
• Passenger weight
• Solo or two-up use
• Typical Tour-Pak, luggage and gear weight
• Motorcycle model and year

This provides an appropriate starting setup from the first ride. Preload can then be adjusted to account for changes in passenger or luggage load.

Your information is reviewed before the shocks are submitted for production. If anything appears incorrect or incomplete, Dreaded Iron Moto will contact you before the build moves forward.

Made in the USA and Individually Tested

Every set of Super Shox SR1 Premier Tri Glide shocks is:

• Precision-machined in the USA
• Hand-assembled
• Individually dyno-tested
• Serial-numbered for traceability
• Built with application-specific spring and damping configurations

This is rider-specific American-made suspension—not a generic replacement shock.

Exhaust Extension Requirements

For a 2017–2025 Tri Glide using 14.5-inch shocks with the factory head pipe and catalytic converter, the Super Shox exhaust extension is required to provide proper swingarm-to-exhaust clearance.

The longer catalytic-converter configuration can limit the suspension extension available with 14.5-inch shocks. The Super Shox extension pipe creates the clearance needed to use the full benefit of the long-travel setup.

Choose:

• With Exhaust Extension — $175 if the factory head pipe and catalytic converter are installed
• No Exhaust Extension only if the Super Shox extension is already installed or your exhaust configuration provides the required clearance

If you are unsure, use the exhaust-extension dropdown above or contact Dreaded Iron Moto. We review your selection before the shocks are built.

What Tri Glide Riders Can Expect

Many Tri Glide riders upgrade because the factory suspension feels harsh, unsettled or tiring over imperfect roads.

A correctly configured SR1 setup can provide:

• A smoother, more composed ride
• Less harsh impact through the seat and handlebars
• Better control with a passenger or loaded Tour-Pak
• A more planted rear end through corners
• Reduced fatigue during long-distance riding
• Less side-to-side disruption over uneven pavement
• Improved muffler clearance on inclines

The objective is not simply to make the suspension softer. It is to improve comfort while maintaining the control a heavy three-wheel touring motorcycle requires.

Installation

• Direct replacement using the factory shock mounting locations
• Do not combine the 14.5-inch shocks with a separate lift kit
• Exhaust extension required with the applicable factory exhaust configuration
• Shocks mount inverted to provide access to the preload adjustment collar
• Professional installation is recommended if you are not comfortable performing suspension work

Lifting the rear of the Tri Glide to unload the suspension makes preload adjustment easier. Once the preferred setting is established, most riders can find one setting that works well across their normal solo and two-up riding.
