RV Performance Suspension Parts for the Workhorse 22 Chassis

If you own a motorhome built on a Workhorse 22 chassis, you know it offers a solid foundation. But like many stock RV suspensions, the factory setup can leave room for improvement, especially when you're dealing with crosswinds, passing trucks, or uneven roads. Upgrading to performance suspension parts tailored for the Workhorse 22 can transform your driving experience—reducing sway, improving steering response, and boosting overall safety. This article covers the most effective upgrades, how they work, and what you should prioritize.

Understanding the Workhorse 22 Chassis and Its Suspension Limitations

The Workhorse 22 chassis is a popular platform for Class A and some Class C motorhomes. It typically features a front I-beam axle and a rear leaf spring setup. While durable, the stock suspension is tuned for comfort rather than precise handling. Common complaints include excessive body roll, wandering on the highway, and a harsh ride over bumps. These issues stem from soft springs, undersized sway bars, and basic shocks. Performance suspension parts address these shortcomings by adding stiffness, damping, and stability without sacrificing ride quality.

Key Performance Suspension Upgrades for the Workhorse 22

Each upgrade tackles a specific handling issue. Here’s what you need to know about the most popular parts.

Steering Stabilizers

A steering stabilizer is a hydraulic damper that mounts to the steering linkage. It reduces bump steer and helps maintain a straight line, especially when hitting potholes or debris. For the Workhorse 22, a heavy-duty stabilizer like those from Safe-T-Plus or Roadmaster can dramatically improve steering control. Installation is straightforward and often takes less than an hour.

Front Sway Bars

An upgraded front sway bar (anti-roll bar) reduces body lean during turns and crosswinds. The stock bar on many Workhorse 22 chassis is relatively thin. Replacing it with a thicker bar, such as the Helwig or Roadmaster heavy-duty front sway bar, can cut body roll by 50% or more. It connects the left and right suspension arms, resisting twisting forces when the chassis leans.

Rear Sway Bars

The rear sway bar works similarly to the front but targets the back of the motorhome. It’s especially beneficial for reducing fishtailing and improving stability when towing a car or carrying heavy loads. A rear sway bar like the SuperSteer Sway Bar or Roadmaster's option helps keep the rear axle planted during lane changes and windy conditions.

Heavy-Duty Shocks

Stock shocks wear out quickly and offer limited damping. Replacing them with high-performance gas shocks, such as KYB Monomax or Bilstein, provides better control over rebound and compression. These shocks reduce nose dive under braking, minimize body motion over bumps, and improve tire contact. For the Workhorse 22, matching shocks to the weight of your RV is critical—select models rated for your motorhome’s gross vehicle weight rating (GVWR).

Air Bags and Helper Springs

Air bags (like Firestone Ride-Rite or Air Lift) are installed inside the rear coil springs or between leaf springs. They allow you to adjust stiffness by adding or releasing air. For a Workhorse 22, air bags are ideal for leveling the coach, reducing sag when loading the basement, and preventing bottoming out. Helper springs, such as SuperSprings, are a simpler alternative that add extra support without air lines.

Full Suspension Kits

Several manufacturers offer comprehensive kits that combine multiple components—often including sway bars, steering stabilizers, and upgraded sway bar brackets. Kits from Roadmaster, SuperSteer, and Henderson’s Line-Up are designed specifically for the Workhorse 22. A full kit ensures all parts work together and simplifies installation. Additionally, consider upgrading sway bar bushings and end links to polyurethane for longer life and tighter response.

Factors to Consider When Choosing Suspension Parts

Not all upgrades are created equal. Here’s how to narrow down options:

• Weight and Load: Your motorhome’s weight determines the necessary stiffness. If you carry extra cargo, a heavier sway bar and air bags are beneficial. Check your GVWR and actual loaded weight before purchasing.
• Driving Environment: If you mostly drive in flat areas, a basic sway bar upgrade may suffice. For mountainous terrain or constant crosswinds, combine a steering stabilizer with heavy-duty shocks.
• Installation Difficulty: Steering stabilizers and sway bars are typically bolt-on with basic hand tools. Air bags require drilling for brackets. If you’re not comfortable, professional installation is recommended.
• Budget: Individual parts range from $100 to $500 per component. Full kits can cost $1,000 to $2,500. Prioritize based on your biggest issue—if sway is the main problem, start with sway bars; if steering wander bothers you, get a stabilizer first.

Practical Final Recommendation: What to Upgrade First

For most Workhorse 22 owners, the best bang for your buck is a heavy-duty steering stabilizer and a front sway bar. These two upgrades directly address the most common complaints—wandering and body roll. They’re relatively affordable and easy to install. If you still feel excessive motion, add a rear sway bar and upgrade the shocks. For those who carry heavy loads frequently, air bags or helper springs should be part of the package.

Remember, upgrading your suspension isn’t just about comfort—it’s about safety. Improved handling reduces driver fatigue and helps you avoid emergencies. After installing any parts, have the alignment checked and adjust tire pressure as needed. With the right combination of performance suspension parts, your Workhorse 22 RV will handle more predictably and ride more securely, mile after mile.
