MORryde CRE3000: Best for a Smoother Ride

The MORryde CRE3000 is widely considered the gold standard for travel trailer owners seeking a noticeable improvement in ride quality without a custom fabrication shop. This rubber-based equalizer replaces the standard steel leaf spring connection, providing up to three inches of suspension travel. By absorbing the energy of road shocks before they transfer to the RV frame, it effectively mitigates the “chucking” sensation often felt in the tow vehicle.

This system is an ideal choice for the weekend warrior or the full-timer who prioritizes a cushioned ride over heavy-duty load capacity. Its design relies on rubber shear springs, which are remarkably effective at dampening high-frequency vibrations from expansion joints and rough pavement. Because it utilizes a simple pivot design, it remains one of the most reliable upgrades for those who want a “set it and forget it” solution.

Choose this kit if the primary goal is protecting fragile electronics, delicate appliances, and the overall longevity of your interior cabinetry. While it does not offer the same heavy-duty dampening as a standalone shock absorber, it provides the most comfort per dollar spent. For the vast majority of standard travel trailers, the CRE3000 strikes the perfect balance between performance and simplicity.

Lippert Road Armor: Toughest All-Around Equalizer

Lippert Road Armor Shock-Absorbing Trailer Equalizer Tandem Axle Kit, 3,500 8,000 lb. Weight Capacity, Easy Aftermarket Upgrade, Substitute for Torsion Axles, Two Pack, 2021015191

When road conditions lean toward the extreme, the Lippert Road Armor system offers a level of durability that standard equalizers simply cannot match. Unlike basic designs, this kit features dual rubber dampeners that compress to absorb both vertical and horizontal forces. This dual-action approach prevents the jarring impacts that lead to chassis fatigue and screw-loosening vibration.

The Road Armor is best suited for long-distance haulers and owners of heavier fifth-wheel trailers who encounter a variety of road surfaces. Its construction is noticeably more robust, signaling a shift from a basic leaf-spring helper to a true suspension component. If you find your current rig suffers from excessive wall separation or persistent interior trim issues, this system is a formidable first line of defense.

This kit is not the cheapest option, but the trade-off is clear: you are paying for structural peace of mind. It is recommended for anyone who refuses to let bad roads dictate their travel schedule. If you value a product that feels overbuilt rather than just adequate, the Road Armor is a sound, long-term acquisition.

SumoSprings Solo Custom: Easiest DIY Upgrade

SumoSprings define the “minimalist” approach to suspension enhancement. These micro-cellular polyurethane springs mount directly to the chassis, filling the gap between the frame and the axle. They operate as a progressive cushion; the more weight is applied, the more they resist, which helps prevent bottoming out during heavy bumps.

Because there is no hardware to pivot or wear out, SumoSprings are essentially maintenance-free. Installation is remarkably straightforward, often requiring little more than a jack, a wrench, and a few minutes of time. This makes them the definitive choice for those who are intimidated by complex suspension overhauls but need a quick fix for a bouncy, unstable ride.

These are an excellent secondary support system, working in tandem with your existing leaf springs rather than replacing them. They are not a total suspension overhaul, so do not expect them to solve deep-seated alignment issues. However, if you want a reliable way to reduce body roll and improve handling for a very modest investment, these are difficult to beat.

Roadmaster Comfort Ride: Top Shock Absorber Kit

The Roadmaster Comfort Ride system takes a more sophisticated approach by integrating shock absorbers directly into the leaf spring system. By controlling the rebound rate of the springs, this kit prevents the trailer from continuing to bounce after hitting a significant dip. It effectively tames the wild oscillations that cause many RVs to feel unsteady during lane changes or high-wind encounters.

This setup is the closest an RV owner can get to a sophisticated automotive suspension without a complete custom air-ride conversion. It requires more time to install than a basic equalizer, but the payoff is a significantly more planted and controlled towing experience. It is the premier choice for those who frequently navigate winding roads or high-altitude mountain passes where stability is non-negotiable.

Invest in the Roadmaster system if you want to elevate your towing experience to a professional level. It is the most comprehensive kit for curbing sway and preventing the repetitive spring oscillation that ruins travel comfort. For owners of large, heavy, or expensive rigs, the comfort and safety benefits justify the extra effort during assembly.

Timbren SES Suspension: Simple No-Maintenance Option

Timbren SES (Suspension Enhancement System) kits serve as an incredibly simple, robust alternative to traditional metal springs. They utilize Aeon hollow rubber springs that carry a significant portion of the load, effectively keeping the RV at the correct ride height. Because these components are designed to be “crushed” safely, they provide a constant, firm cushion that refuses to sag over time.

For those who boondock or travel on unimproved forest service roads, the Timbren system offers unmatched reliability. There are no ball joints, no grease fittings, and no internal air bladders to puncture or leak. Once these are installed, they rarely require anything beyond a visual inspection, making them a top choice for travelers who prefer to spend time camping rather than under the trailer.

These are not designed to provide a soft, “luxury sedan” feel; they provide a firm, controlled ride. If you prioritize durability and absolute simplicity over a plush experience, look no further. This is the ultimate “install it and forget it” upgrade for those who prioritize ruggedness.

Dexter E-Z Flex: A Trusted Budget-Friendly Pick

Dexter E-Z Flex Equalizer Tandem Kit (Red powder coat) K71-652-06

The Dexter E-Z Flex is a classic, widely available equalizer that represents the standard benchmark for suspension upgrades. By adding a rubber core to the existing shackle assembly, it helps neutralize the harsh impacts that standard steel-on-steel joints fail to address. It is a proven, entry-level upgrade that brings immediate improvement to the harshness of a stock suspension.

What makes the E-Z Flex particularly attractive is the ease of sourcing parts and the massive knowledge base surrounding its installation. It is a cost-effective way to transition away from factory-grade hardware without venturing into specialized or boutique equipment. For many mid-sized trailers, this is exactly the level of improvement needed to make a long haul bearable.

This kit is the perfect starting point for the budget-conscious owner who wants to improve their rig without high costs. While it lacks the sheer dampening capacity of higher-end shock-based systems, it does exactly what it promises. For those looking for a sensible, reliable upgrade, the E-Z Flex is a solid, conservative choice.

Does Your RV Really Need a New Suspension?

Determining the necessity of an upgrade starts with a simple audit of your current experience. If you notice interior trim pieces popping off, cabinet doors opening during transit, or a persistent “porpoising” motion in your tow vehicle, your suspension is failing to absorb energy. In these instances, the suspension is not just a comfort issue; it is a long-term maintenance liability.

Conversely, not every trailer requires a full-scale performance overhaul. If the trailer tracks straight, exhibits no excessive bounce, and remains level under load, the factory setup is likely sufficient for your current usage. Upgrades should be viewed as a solution to a specific problem, not a generic prerequisite for RV ownership.

Always look for signs of “suspension fatigue” before spending money. Inspect the leaf springs for flattened arcs, check the nylon bushings for excessive wear, and verify that the equalizer is not resting against the frame. If the current components are showing signs of metal fatigue, an upgrade is a practical investment in the trailer’s lifespan rather than a vanity project.

Sizing Your Kit: Don’t Skip This Step

The most common mistake during an upgrade is assuming all “standard” RV suspensions are identical. Before purchasing any kit, you must verify your axle capacity, the distance between the leaf spring eyes, and the specific bolt configuration of your current hangers. Measuring from center-to-center on the mounting holes is the only way to ensure the components will align correctly upon arrival.

Pay close attention to weight ratings and trailer length requirements specified by the manufacturer. Installing a kit designed for a light 20-foot trailer on a heavy 35-foot fifth-wheel will lead to immediate failure and potential roadside safety hazards. Always cross-reference the GVWR (Gross Vehicle Weight Rating) of your trailer with the maximum capacity of the kit you are considering.

When in doubt, consult the manufacturer’s documentation rather than relying on dealership descriptions. If your specific trailer model year saw a mid-production change in axle manufacturer, measure the existing hardware yourself. A precise measurement saves hours of frustration and prevents the need for costly return shipping.

Quick Assembly Tips for a Safe DIY Install

Proper assembly begins with safety. Never rely solely on a standard vehicle jack to hold a trailer frame while working underneath; utilize heavy-duty jack stands rated for the full weight of the trailer. Once the wheels are removed and the frame is supported, take the time to clean the hanger mounting points with a wire brush to ensure flush, metal-to-metal contact for all new hardware.

Torquing fasteners to the manufacturer’s exact specifications is the difference between a successful install and a roadside failure. Many suspension kits utilize “wet” bolts or specialized shackle links; ensure that any grease zerks are pointed in an accessible direction for future maintenance. A dry, over-tightened bolt can snap under the immense shear forces exerted while turning or traversing uneven terrain.

Always replace the bushings and bolts included in the kit, even if the existing ones appear functional. Mixing old, worn hardware with new, precision-engineered suspension components creates weak points that invite premature failure. Take a final walk-around to ensure all cotter pins are seated and that every nut has been properly torqued to the requested foot-pounds.

Equalizers Shocks or Springs? Find Your Fit

The choice between an equalizer, a shock system, or an auxiliary spring is ultimately determined by how and where you travel. If you stay on major highways and prioritize interior comfort, a rubberized equalizer like the MORryde CRE3000 is likely the most efficient use of your budget. These provide the greatest “cushion” for a reasonable investment.

For those who frequent winding mountain passes or high-speed interstates, the sway-dampening benefits of a shock absorber system are worth the added complexity. Controlling spring oscillation is the key to preventing “trailer sway,” which is the primary cause of white-knuckle driving. If stability is your biggest concern, look toward the Roadmaster or similar shock-integrated solutions.

Finally, consider the Timbren or SumoSprings options if you spend significant time on gravel, dirt, or rough access roads. These systems offer the best resistance to bottoming out and provide a durability that metal-heavy systems cannot match in harsh environments. By aligning the kit choice with your specific travel style, you ensure the upgrade provides real value for every mile traveled.

Upgrading your RV suspension is a transformative project that directly impacts both your equipment’s longevity and your peace of mind on the road. By moving away from baseline factory components, you reclaim control over the ride quality and protect your mobile home from the inevitable wear of the open road. Take the time to measure correctly, choose based on your specific terrain, and execute the installation with attention to detail.
