Which Aftermarket RV Suspension Upgrades Are Right for You?

Mainline Truck Team • August 7, 2023

When you buy a new RV and drive it off the lot, you want it to come pre-loaded with all the best equipment. Unfortunately, that's not always the case.  In particular, there's an unfortunate tendency for RVs to come with substandard suspension, resulting in a rough and unpleasant ride and too much sway.


A good RV suspension system is needed for a smooth ride, which is why most RV enthusiasts take the time to invest in RV suspension upgrades.  The extra investment can result in a much more enjoyable trip, and one you'll really appreciate after hours behind the wheel.


What are your options in RV suspension upgrades? These are some of the components that are most commonly upgraded.


Upgrade Your Ride: Choosing the Right RV Suspension Upgrades

 

Traveling in an RV, whether it's a short weekend getaway or a long, cross-country adventure, offers a unique experience of convenience, comfort, and freedom. But, to keep the journey smooth and enjoyable, it's crucial to pay attention to one key component: your RV's suspension system.

 

The suspension system of an RV bears the weight of the vehicle, contributes to handling and braking, and cushions the ride from bumps and uneven roads. However, the standard suspension systems that come with most RVs might not provide the ride quality you want. That’s why getting the best RV suspension upgrades is worth considering to enhance your overall travel experience.

 

Let’s explore the essentials of RV suspension, the top aftermarket upgrades, and where to get better motorhome suspension upgrades.

 

The Essentials of RV Suspension

 

The suspension system of an RV is a complex combination of components that work together to provide stability, control, and comfort. It primarily consists of springs, shock absorbers, axles, and linkages that connect the vehicle to its wheels. A basic understanding of these components is important before choosing an aftermarket upgrade.

 

Leaf Spring Suspension

 

This is the oldest and most commonly used type of suspension system in RVs. It consists of several layers of metal (known as 'leaves') that are curved and stacked on each other.

 

Torsion Bar Suspension

 

A torsion bar suspension system uses a steel rod to bear the vehicle's weight. It's more compact and offers a smoother ride than leaf spring systems, but it's also more expensive.

 

Top of the Line Independent Suspension Plus a Disc Brake Upgrade

 

While leaf springs, torsion bars, and air suspensions are the common types, there's a more advanced option available for those who want the best of the best: independent suspension systems.

 

Independent Suspension System

 

Unlike other suspension types, where each axle is connected to the vehicle, independent suspension systems allow each wheel to move separately. This drastically improves ride quality and handling, particularly over uneven terrain.

 

When upgrading to a top-of-the-line suspension system, it's advisable to also consider a disc brake upgrade. Disc brakes offer superior stopping power compared to the traditional drum brakes that come standard on most RVs. They are less prone to overheating and more reliable, particularly in hilly or mountainous terrains.

 

Some Other Upgrades for RV Suspension

 

While upgrading to an independent suspension system and disc brakes is a significant improvement, there are other upgrades that can enhance your RV's ride quality.

 

Shock Absorbers

 

Upgraded shock absorbers can significantly improve your ride quality by minimizing bounce and sway. Bilstein and KONI are among the leading brands offering high-quality shocks for RVs.

 

Sway Bars

 

A sway bar, or anti-sway bar, helps reduce the RV's body roll during sharp turns or wind gusts. An upgraded sway bar can improve the vehicle's stability and handling.

 

Air Bags

 

Air bag suspension kits can enhance the ride quality of leaf spring and torsion bar systems. They can be inflated to increase lift and support additional weight or deflated for a softer ride.

 

Disc Brakes: What You Need to Know

 

When considering upgrading your RV's braking system, disc brakes offer significant advantages over traditional drum brakes.

 

Disc brakes use a hydraulic system that presses brake pads onto a rotor to slow or stop the vehicle. They dissipate heat more effectively than drum brakes, resulting in improved braking performance and reduced risk of brake failure during prolonged use.

 

Disc brakes require less maintenance than drum brakes, which can save you time and money in the long run. However, they are more expensive upfront. But for most RV owners, the increased safety and performance is worth the cost.


What Types of RV Suspension Upgrades Do You Need?


Depending on the issues you're having with your stock suspension, you might look into:


1 - Sway bars

One of the most useful overall upgrades, sway bars add a spring-loaded steel bar that connects the truck frame and axles. These are intended to absorb side-to-side movement and reduce sway - which is particularly important for taller vehicles.


2 – Sumo springs

Adding Sumo Springs to your existing suspension greatly reduces sway when cornering 

Just be aware, that adding sway bars and/or leaf springs can potentially make handling somewhat stiffer.  This is usually an acceptable tradeoff, particularly if you're concerned about swaying or rollover.


3 - Better shocks

Shock absorbers are one of the key components of virtually any suspension system.  They are a hydraulic device specifically designed to absorb and control the impact and rebound movement of your vehicle's springs and suspension.  Shocks are also designed to make sure your vehicle's tires remain in contact with the road. Mainline recommends a Koni shock.

Why Have a Maintenance Contract for Your Truck and Trailer Repair in Ohio

By Mainline Truck Team • May 13, 2025
One of the most important aspects of commercial fleet management is basic truck and trailer repair and maintenance. Unfortunately, this can be one of the most difficult and time-consuming tasks as well - yet it's absolutely necessary for your fleet to be reliable day after day. That's why more Ohio businesses are seeking reliable maintenance contracts with experienced providers for their truck and trailer repair. Repair pros can make basic maintenance easy and often provide so many additional benefits that the costs easily bring superior returns over time. Specialists Improve Your Truck and Trailer Repair Services The most basic reason to partner with a contracted truck and trailer repair service is to benefit from their expertise. Unless your repair crew has been in the field for many years, they're unlikely to have the same breadth of experience as an Ohio repair shop that's been around for decades. This gives specialty shops a real edge, since they've worked with a huge range of vehicles and have likely seen just about every problem that could possibly occur. They'll also have deep experience diagnosing future problems from minor current maintenance issues. Expert preventative care will pay off by preventing on-road breakdowns and other problems that can harm your productivity. Improved Documentation and Record-Keeping Staying on top of truck maintenance also requires a lot of record-keeping. For example, just about every major component in a truck or trailer has its own expected lifespan and end-of-life date. Are you keeping track of all these dates, so you know in advance when it's time to replace an older component? Truck and trailer repair specialists can keep track of all this, and more. They'll stay on top of end-of-life dates and recommend replacements before an older component has the chance to fail. They'll also keep extensive documentation on all repairs and maintenance done, so if something does go wrong, the electronic records should show the point of failure. Roadside Services Exact services here can vary between providers, but most shops who offer maintenance contracts also offer extended services. They may be able to provide emergency roadside repairs or pickup, which can be a lifesaver both literally and figuratively. Mainline RV & Truck Service Is Your All-Purpose Ohio Truck Maintenance Partner Since 1982, we've been offering superior truck and trailer repairs, upgrades, and other services in Ohio. We see drivers come in from across the state because they know our expertise is second to none - and your business can benefit from our long experience as well! If you're having trouble keeping up with maintenance, don't let all the little issues pile up. Mainline can take on any level of responsibility for your fleet, from occasional repairs to full day-to-day fleet management, guaranteeing high productivity the whole way.
