Fleetwood motorhomes and travel trailers are known for their comfort and reliability on the road. But even the best-built RV needs proper suspension maintenance to ensure a smooth ride, stable handling, and long-term durability. Whether you own a Bounder, Southwind, or Pace Arrow, understanding the suspension system and knowing which parts to replace or upgrade can save you time, money, and headaches.

Understanding Your Fleetwood RV Suspension System
The suspension system on a Fleetwood RV is designed to absorb road shocks, support the vehicle's weight, and keep the tires in contact with the road. While the exact setup varies by model and year, most Fleetwood RVs use a combination of leaf springs, shock absorbers, sway bars, and sometimes air springs.
Key Components
Leaf Springs are the backbone of many RV suspensions. They consist of several layers of steel bands that flex under load. Over time, leaves can sag or break, leading to a rough ride and poor weight distribution.
Shock Absorbers control the rebound of the springs. Worn shocks cause excessive bouncing, sway, and reduced braking stability. Fleetwood often uses gas-charged shocks for better damping.
Sway Bars (anti-roll bars) reduce body lean during turns and crosswinds. They connect the left and right sides of the suspension. A broken or loose sway bar link can make an RV feel tippy.
Air Bags are optional on many Fleetwood models. They allow you to adjust ride height and stiffness by adding or releasing air. Air bags are especially useful for leveling when parked or leveling a heavy load.
Steering Stabilizers and track bars help keep the axle centered and reduce steering wander. These are common on larger Class A motorhomes.
Common Suspension Problems in Fleetwood RVs
Even with regular care, RV suspension parts wear out. Knowing the signs of trouble can help you address issues early.
Sagging Springs
Over time, leaf springs lose their arch. You might notice the RV sits lower on one side, or the ride becomes harsh because the springs bottom out. Sagging springs also accelerate tire wear. If you see cracks in the leaves or hear clunking over bumps, it's time for replacement.
Worn Shocks
Shocks typically last 30,000 to 50,000 miles. Telltale signs include fluid leaks, a bouncy ride, or excessive sway after passing a truck. When shocks are shot, the RV feels like a boat on rough roads. Always replace shocks in pairs (front or rear) for balanced handling.
Air Leaks in Air Systems
For RVs with air suspension, leaks are common. You may hear hissing, or the RV may sag overnight. Check air lines, fittings, and the air bags themselves for cracks. A small leak can cause the compressor to run constantly, shortening its life.
Loose or Broken Sway Bar Links
A clunking noise when turning or going over speed bumps often points to worn sway bar bushings or links. Left unchecked, this can lead to broken sway bars and unstable handling.
How to Choose the Right Fleetwood RV Suspension Parts
Selecting parts for your Fleetwood requires attention to weight ratings, model year, and your driving habits.
OEM vs Aftermarket
Original Equipment Manufacturer (OEM) parts are made to Fleetwood's specifications. They guarantee a direct fit but can be expensive. Aftermarket parts offer more variety, often with upgraded materials like polyurethane bushings or heavier-duty springs. If you carry heavy loads or tow frequently, aftermarket upgrades like Sumo Springs or Timbren SES may reduce sag and improve control.
Weight Ratings
Every suspension component has a load rating. For leaf springs, look for the gross axle weight rating (GAWR) of your RV. Heavier springs provide more support but can make the ride stiffer when unloaded. Air bags allow you to adjust stiffness on the fly.
Compatibility with Model Year
Fleetwood has produced many models over decades. Parts for a 1990s Holiday Rambler may differ from a 2010s Bounder. Always confirm your RV's exact model, year, and axle configuration. Use your VIN when ordering to ensure correct fitment.
Build Quality
Check for rust protection. Many aftermarket springs come powder-coated or painted. Shock absorbers should have a warranty of at least two years. For air bags, look for reinforced rubber and stainless steel mounting brackets.
Installation Tips and Considerations
Installing suspension parts can be a DIY job if you have basic tools and a safe way to support the RV. However, many components are heavy and require precise torque specs.
- Always chock the wheels and use jack stands rated for the RV's weight.
- For leaf springs, replace the U-bolts and any bushings at the same time.
- When replacing shocks, loosen the top nut before jacking up the suspension.
- If installing air bags, plan the air line routing carefully to avoid chafing.
- After installation, get a professional alignment. Changed suspension components can alter toe-in and camber, leading to tire wear.
Professional installation is recommended for air systems and complex upgrades like complete spring replacements. A certified RV technician can ensure everything is safe and properly adjusted.
Recommended Approach for Upgrading
If your Fleetwood RV feels unstable or sags under load, start with the basics. Check tire pressure and inspect all spring leaves and shock bolts. Replace any obviously worn parts before considering upgrades.
For sagging, leaf springs are the most effective fix. Consider aftermarket springs with an extra leaf or a higher load rating if you often travel heavy. Combine with new gas shocks for a smoother ride.
For sway control, a heavy-duty sway bar or a rear track bar can make a noticeable difference. These are relatively affordable and easy to install.
If you want adjustable ride height, air bags are a popular upgrade. They allow you to level the RV when parked and increase stiffness when needed. However, they add complexity and require periodic maintenance.
Final Recommendation
Start by diagnosing your current suspension condition. Look for sag, leaks, or noise. Replace worn components with quality parts that match your Fleetwood's specifications. For most owners, a combination of new leaf springs, upgraded shocks, and a rear sway bar provides a significant improvement in ride and handling. If you need extra support for heavy loads, consider air bags or add-a-leaf kits. Always prioritize safety over cost, and don't hesitate to consult a professional for complex jobs. With the right parts and maintenance, your Fleetwood RV will continue to deliver comfortable miles for years to come.
