Super Shox Premium SR2 Rear Shocks | Harley-Davidson Road Glide (02'-Present)

Super Shox Premium SR2 Rear Shocks
Harley-Davidson Road Glide (2002–Present)

Super Shox SR2 rear shocks are American-made suspension built for Road Glide riders who want more usable travel, better load support, and greater control than factory rear suspension typically provides.

Each set is configured around your rider weight, passenger use, luggage, Tour Pack, and normal riding load. Super Shox manufactures, assembles, tests, and dyno-tunes its motorcycle suspension at its facility in Grayslake, Illinois.

For most two-wheel Road Glide riders, SR2 LT is the recommended starting point. It combines approximately 3.5 inches of suspension travel with a relocation mount on each side that keeps the bike at stock ride height.

Dreaded Iron Moto is an authorized U.S. Super Shox retailer. We review your motorcycle and rider information before submitting the build, helping catch incorrect fitment or setup details before production begins.

Most Road Glide Riders Should Start With SR2 LT

SR2 LT is designed for Road Glide riders who prioritize comfort, control, and usable suspension travel over simply choosing the shortest shock.

Choose SR2 LT if you want:

• Approximately 3.5 inches of suspension travel

• Better control over rough or broken pavement

• Improved support when riding two-up

• More control when carrying luggage or a Tour Pack

• Reduced harshness and bottoming

• A stable, planted feel through curves

• Better long-distance comfort without raising the motorcycle

The included relocation mounts, one on each side, create additional usable travel. The spring and damping configuration is engineered specifically for that mounting position.

LT is not a taller shock or lift kit. It keeps the bike at stock ride height.

SR2 LT vs. SR2 SL

SR2 LT uses a relocation mount on each side. SR2 SL is a 13" shock that goes on the stock mounts, using the stock bolt.

SR2 LT — Recommended for Most Riders

SR2 LT uses a 14-inch shock with approximately 3.5 inches of travel.

According to Super Shox:

• LT keeps the bike at stock ride height, with a relocation mount on each side

LT is the strongest starting point for riders who prioritize maximum usable travel, two-up support, loaded touring, and long-distance comfort.

SR2 SL — About 1/2 Inch Lower

SR2 SL is a 13" shock that goes on the stock mounts, using the stock bolt.

According to Super Shox:

• SL sits about 1/2 inch lower than stock

Most riders choose LT. Choose SL if you want to sit about 1/2 inch lower than stock and are fine with less suspension travel than LT.

When lowering any motorcycle, tire clearance, fender clearance, exhaust clearance, load, and full suspension movement must be checked carefully.

Built Around Your Actual Riding Load

Two riders can own the same Road Glide and place completely different demands on the rear suspension.

A solo rider without luggage does not need the same spring and damping configuration as a rider carrying a passenger, loaded saddlebags, and a Tour Pack.

Your Super Shox build is configured using:

• Road Glide year and exact model

• Rider weight with normal riding gear

• Passenger weight

• Typical luggage or cargo

• Percentage of two-up riding

• Tour Pack use

• Normal riding conditions

This information does not determine whether you need SR2 LT or SR2 SL. It allows Super Shox to establish the appropriate spring and damping configuration after you select the geometry and ride height that fit your goal.

Super Shox offers an extensive range of spring rates and damping configurations instead of limiting riders to a basic standard-duty or heavy-duty choice.

What Road Glide Riders Commonly Notice

Compared with factory Harley-Davidson Touring suspension, riders commonly report:

• Less harshness over expansion joints

• Better absorption of larger bumps

• Reduced bottoming

• Less rear-end kick over choppy pavement

• Better stability with a passenger or luggage

• A calmer feel at highway speed

• Improved cornering confidence

• Less upper-back and tailbone fatigue during long rides

Actual results depend on the motorcycle, condition of the original suspension, total riding load, selected SR2 configuration, and proper preload setup.

American-Made and Dyno-Tuned in Illinois

Super Shox is not an imported shock relabeled for the Harley market.

Its motorcycle suspension is manufactured, assembled, tested, and dyno-tuned in Grayslake, Illinois. Each SR2 build combines American-made construction with a spring and damping configuration selected around the motorcycle and submitted rider profile.

Construction features include:

• Gas-assisted monotube design

• Aircraft-grade aluminum components

• Durable anodized finish

• High-strength, low-friction shaft

• Deflective-disc valving

• Sealed gas chamber

• Spherical bearing mounts

• Calibrated preload adjustment

• Multiple spring-rate and damping configurations

• Precision-machined relocation hardware

These components are designed to provide consistent suspension movement and maintain control as road conditions, speed, and motorcycle load change.

Deflective-Disc Valving

A shock must react to smaller road imperfections without losing control during larger impacts.

Super Shox uses deflective-disc valving to provide responsive initial movement while maintaining the damping control needed over larger bumps, potholes, expansion joints, and repeated rough pavement.

Its sealed gas-chamber design also helps reduce cavitation—the formation of bubbles in the shock oil that can make damping less consistent.

Spherical Bearing Mounts

Traditional rubber-style shock mounts can introduce resistance as the suspension moves and the motorcycle leans.

Super Shox uses spherical bearing mounts that allow freer movement at the mounting points. This helps reduce suspension bind and allows the shocks to respond more naturally through curves and uneven pavement.

Tool-Free Preload Adjustment

Road Glide riders rarely carry the same load on every ride.

The calibrated preload adjustment system makes it easier to compensate when changing between:

• Solo riding

• Solo riding with luggage

• Two-up riding

• Two-up riding with loaded saddlebags

• Tour Pack and multi-day travel loads

The shocks arrive preset for you and your bike, with a chart that shows exactly where they’re set.

Preload changes compensate for changes in load. They do not replace the correct spring and damping configuration established when the shocks are built.

Installation and Included Hardware

SR2 is designed as a bolt-on rear suspension upgrade for compatible Harley-Davidson Road Glide models.

• SR2 LT: Includes a relocation mount for each side

• SR2 SL: Goes on the stock mounts, using the stock bolt

• No cutting or permanent frame modification is required

• Normal preload adjustments do not require special tools

• Installation instructions and a preload setup chart are included

The relocation mounts are precision-machined from 6061 aluminum with a steel mounting stud. They are designed to lock into the swingarm and maintain appropriate clearance with the shock and saddlebags.

Always support the motorcycle properly and follow the supplied installation instructions. If you are not comfortable working on motorcycle suspension, installation by a qualified technician is recommended.

Ride Height and Shock Length

Super Shox describes its Touring suspension around the intended installed riding stance—not only an unloaded eye-to-eye measurement taken before installation.

An uninstalled shock may measure differently from the motorcycle’s settled ride height. Original shock length, rider weight, spring configuration, preload, relocation geometry, and proper sag all affect the final stance.

For that reason, do not select SR2 solely by comparing an unloaded shock measurement with the motorcycle’s current settled height.

• Choose LT when usable travel, loaded support, and long-distance comfort are the priorities

• Choose SL if you want to sit about 1/2 inch lower than stock, with less travel than LT
