Enhance Your Rides With RWD Suspension Upgrades for Harley

• RWD components feature Active Valve Technology (AVT) and reservoir designs that provide a plush ride over small bumps while maintaining firm control on heavy impacts.
• With options for standard or heavy-duty spring rates and multiple shock lengths, riders can customize their bike’s geometry and load capacity for solo cruising or two-up touring.
• Upgrading to RWD suspension eliminates the “wobble” found in factory setups, providing increased lean angles and consistent tire-to-road contact for safer cornering and braking.

The stock suspension on many Harley-Davidson motorcycles often leaves something to be desired. If you’ve spent enough time in the saddle, you likely know the feeling of a harsh jolt after hitting a pothole or the wallowing sensation during a high-speed turn. Factory setups, particularly the air-assisted shocks on older Touring models, are often built to a budget and struggle to maintain composure under heavy loads.

If you’re looking for top-tier Harley suspension upgrades, you came to the right place. Switching to high-performance components from Russ Wernimont Designs (RWD) for Harley-Davidson motorcycles can transform your ride by balancing plush comfort with razor-sharp handling.

In this guide, we’ll discuss why RWD shocks and other suspension components can be the Harley suspension upgrade that you’re looking for in your Touring or Softail model.

What Is RWD Suspension?

Russ Wernimont Designs, now known as RWD V-Twin, is a high-performance specialist that focuses on engineering solutions for Harley-Davidson motorcycles. They do not make generic parts. Every component is designed to handle the weight and torque of large American V-Twin engines, as in Harley-Davidson motorcycles.

Harley enthusiasts value RWD because of these core technologies:

• Active Valve Technology (AVT) is a position-sensitive damping system that allows the shock to be soft over small road chatter while firming up instantly to prevent bottom-outs on large hits.

• The heat management system of RWD is efficient, with many models featuring drop-down or piggyback reservoirs. These keep the shock oil cool, ensuring consistent damping performance even on long rides through the desert heat.

• Precision Adjustability: With a 12-click compression adjuster, you can fine-tune your ride from a soft cruising feel to a firm performance setup in seconds.

• High-End Construction: All components are billet-machined rather than cast. They feature 5/8-inch low-friction shafts and high-flow pistons for maximum durability.

Comparing RWD Suspension and Stock Harley Suspension

It helps to see how these upgrades stack up against the factory equipment. Standard shocks often feel limited because they lack the sophisticated valving found in performance sets.

RWD wins because they offer a superior balance of value and performance. While factory air shocks on a Street Glide can feel punishing on rebounds, RWD shocks stay planted and smooth.

Benefits of Upgrading to RWD Suspension for Your Harley

Upgrading your Harley shocks provides more than just a smoother ride. It impacts the safety and longevity of your motorcycle. 

1. Enhanced Comfort on Long Rides

Quality suspension soaks up expansion joints and road chatter. This reduces the physical strain on your body, allowing you to ride for hours without the usual back or neck fatigue.

RWD, for instance, focuses on damping control. RWD shocks use high-quality internal valving that separates the oil and nitrogen. This prevents aeration (foaming), meaning the shocks perform just as consistently on the 200th mile as they did on the first.

2. Improved Handling and Cornering Control

Harleys, especially heavy Touring models (Street Glides, Road Glides), often suffer from a phenomenon known as “rear-steer” or “the wobble” in high-speed sweepers. Upgrading with RWD shocks help with your bike’s lateral stability by keeping the swingarm aligned and reducing mid-corner wallow. Doing so also increases your lean angle, allowing you to navigate tight mountain switchbacks without scraping your floorboards or primary cover.

3. Custom Adjustability for Every Load

Whether you are riding solo, carrying a passenger, or hauling a week’s worth of luggage, you can adjust the compression with a simple clicker. You no longer have to settle for a setup that’s too soft for two-up riding or too stiff for a solo cruise.

4. Increased Safety and Stability

Harley touring shocks from RWD ensure you r rear tire maintains better contact with the road. They often feature threaded preload and compression damping adjustments. Consistent damping means more predictable braking and better traction when you need it most.

RWD Suspension for Harley Touring Models

If you ride a Street Glide, Road Glide, or any FL model from 1999 to 2025, you know the struggle with road harshness. RWD suspension touring kits, specifically the RS-2 rear shocks, are designed to solve this.

These bolt-on units feature a sleek one-piece body with drop-down reservoir for superior bump zone protection and bottom-out resistance, paired with 12-click compression adjustment for tuning from plush comfort to sharp performance.

RWD Suspension for Harley Softail Models

The newer M8 Softail models (2018 and up) have a powerful engine but a rear shock that can feel stiff. RWD suspension softail upgrades bring a new level of refinement to these cruisers.

The RS-2 monoshock for Softails features a remote reservoir that mounts to the swingarm. It often adds a bit of ride height, which provides more lean angle for aggressive riders. With Eibach springs, high-flow pistons, and a lifetime warranty, it’s ideal for smoothing daily commutes without compromising sportbike-like performance.

Choosing the Right RWD Setup for Your Harley

Most RWD rear shocks are direct bolt-on replacements. They use factory mounting points and require no cutting or welding. However, choosing the right setup is important:

Spring Weight

Harley-Davidson touring models often come stock with 12-inch or 13-inch shocks. RWD offers lengths that can drastically change the geometry of your bike:

• 13-inch (Standard Replacement): Best for riders who want to maintain the stock height and "low-slung" look while significantly improving ride quality over the factory air or emulsion shocks.

• 13.5-inch (The Performance Sweet Spot): This is the “Goldilocks” length for many bagger riders. It provides extra suspension travel (the distance the shock can move before bottoming out) and slightly raises the rear to improve turn-in response.

• 14-inch (Tall Bagger Style): Preferred by aggressive riders. The extra height provides maximum lean angle, preventing floorboard scraping in tight corners.

Length

RWD shocks use high-quality springs that are wound specifically for different loads. Choosing the wrong one can lead to a ride that is either too harsh or prone to bottoming.

• Standard Duty (SD): Optimized for solo riders or those who prioritize a plush, cloud-like feel on the highway. Usually rated for total loads of approximately 250 lbs to 275 lbs; note that actual values depend on rider weight, passenger, and gear.

• Heavy Duty (HD): Designed for riders who spend 50% or more of their time riding two-up or carrying heavy luggage (Tour-Paks, tools, etc.). If you are a larger rider or frequently tour, the HD spring prevents the wallowy feeling in high-speed turns.

Front and Rear Balance

One of the most overlooked aspects of suspension is pitch. If you only upgrade the rear, you create an imbalance.

Pairing the rear with RWD Front Cartridge Kits replaces the outdated damper rod technology inside your forks. This keeps the bike level during braking and acceleration, ensuring the front and rear are working in harmony rather than fighting each other.

Frequently Asked Questions About RWD Suspension

What are signs of bad rear suspension?

If your bike bounces several times after hitting a bump, the damping is likely worn out. Other signs include oil leaking from the shock body, uneven tire wear, or a clunking sound when the suspension compresses.

Is it better to have stiffer or softer suspension?

It depends on your riding. A softer suspension is more comfortable for slow cruising on smooth roads. A stiffer suspension provides better control for aggressive riding and prevents the bike from bottoming out under heavy loads. The goal is to find a balance where the suspension stays in the middle of its travel.

What happens if the rear suspension is too stiff?

If the suspension is too stiff, the tire may lose contact with the road on bumpy surfaces. This leads to a harsh ride that can cause rider fatigue and reduced traction during cornering or braking.
