MORryde CRE3000: Best All-Around Upgrade

The CRE3000 equalizer system is widely considered the gold standard for travel trailers that see a mix of highway miles and occasional rough terrain. It replaces standard flat leaf spring equalizers with a system that provides three inches of vertical travel, effectively absorbing road shock before it reaches the frame. This additional travel is a game-changer for protecting sensitive interior components like cabinetry and appliances from vibration fatigue.

This system is the ideal choice for the weekend warrior or the seasonal traveler who occasionally ventures onto gravel or uneven campground roads. It excels at smoothing out those jarring transitions between paved roads and campsite entrances, significantly reducing the stress on spring hangers. If the goal is a balanced, reliable ride without the complexity of a complete air suspension overhaul, the CRE3000 is the clear, logical choice.

Dexter E-Z Flex: Top OEM-Level Upgrade

For those seeking a high-quality upgrade that feels like it could have rolled off the assembly line, the Dexter E-Z Flex is a top-tier contender. It functions similarly to standard equalizers but utilizes rubber compression inserts to dampen road harshness. The beauty of this system lies in its simplicity; it provides a measurable improvement in ride quality while remaining straightforward to maintain.

This product is highly recommended for RV owners who prioritize reliability and ease of service above all else. Because it relies on high-quality rubber rather than complex mechanical joints, it is less prone to sudden failure on long cross-country hauls. For anyone who wants a plug-and-play upgrade that keeps the rig stable and quiet on the interstate, the E-Z Flex is the most dependable path forward.

Lippert Road Armor: Best for Heavy Rigs

Large, heavy fifth wheels and toy haulers exert tremendous force on suspension components, making standard parts a liability. The Lippert Road Armor system is engineered specifically for these weight classes, utilizing a proprietary shock-absorbing rubber core to mitigate the “chucking” sensation common in larger towables. It is built to withstand the higher tongue weights and dynamic forces that cause lighter systems to bottom out.

Choosing this system is a necessity if the rig weighs in at the upper end of the towing spectrum. It provides the heavy-duty dampening required to keep large structures stable during emergency maneuvers or sudden road changes. When the rig is heavy, don’t cut corners; choose the system that treats the suspension as the load-bearing foundation it actually is.

SuperSprings SumoSprings: Best for Sway Control

SumoSprings aren’t traditional bushings, but they are an essential suspension upgrade that pairs perfectly with upgraded shackle kits. These micro-cellular polyurethane units act as progressive bump stops that engage gradually, providing constant contact and support. They are incredibly effective at reducing side-to-side body roll when cornering or navigating uneven terrain.

If the primary frustration is trailer sway in high winds or a feeling of “floating” on the highway, SumoSprings provide the solution. They are maintenance-free, weather-resistant, and install relatively quickly compared to suspension overhauls. For those who want to stabilize their rig without replacing the leaf spring system, this is an inexpensive, highly effective insurance policy.

Roadmaster Comfort Ride: The Ultimate Shock Add-On

The Roadmaster Comfort Ride system represents the pinnacle of suspension modification for those who demand a premium towing experience. By incorporating a slipper spring leaf system and integrated shocks, it isolates the frame from the axle to a degree that standard equalizers simply cannot match. It effectively turns a harsh trailer ride into a controlled, fluid movement that mimics the stability of a high-end tow vehicle.

This is the definitive upgrade for full-timers who spend thousands of miles a year on the road. While the installation process is more involved than a simple bushing swap, the long-term payoff in chassis longevity is unmatched. If the priority is absolute comfort and the protection of a high-value home on wheels, the Roadmaster system is worth the investment.

Energy Suspension Polyurethane: Best DIY Bushing Kit

Factory plastic or soft rubber bushings often deform within the first few thousand miles, leading to clunking and alignment issues. Energy Suspension’s polyurethane kits replace these weak points with a material that is virtually impervious to road grime, heat, and weight cycles. They are the most cost-effective way to tighten up a loose, rattling suspension assembly.

These kits are a perfect Saturday morning project for the mechanically inclined owner who wants a firmer, more responsive towing feel. The tighter tolerances provided by polyurethane eliminate the “slop” in the leaf spring eyes, ensuring the axles stay perfectly aligned. If the budget is tight but the suspension is neglected, starting with an Energy Suspension kit is the best decision one can make.

MORryde Wet Bolt Kit: Best for Durability

A suspension system is only as good as its weakest link, which is often the shackle bolt itself. The MORryde Wet Bolt kit replaces standard “dry” bolts with high-strength, greaseable versions that feature a channel for lubricating the bronze bushings directly. Regular greasing keeps the suspension joints moving freely, preventing the metal-on-metal friction that destroys hangers over time.

This kit is non-negotiable for anyone serious about off-road or high-mileage travel. Without a wet bolt system, bushings will inevitably fail, leading to wallowed-out spring eyes and expensive frame repairs. Think of this as the primary maintenance upgrade that makes all other suspension mods last twice as long.

Signs Your Factory Bushings Need an Upgrade

The most obvious sign of failing bushings is a rhythmic squeaking or clunking noise coming from the wheels when traversing bumps or tight turns. Upon visual inspection, look for “wallowed” or oblong holes in the shackle plates or leaf spring eyes, which indicate significant metal-on-metal wear. Uneven tire wear is another major red flag, suggesting that the axle is no longer tracking straight due to slop in the suspension.

• Excessive vibration: If kitchenware or cabinet contents are displaced after short drives on paved roads.
• Visible deformation: If the rubber bushings appear squashed, cracked, or are completely missing from the spring eye.
• Difficulty tracking: If the trailer feels unstable or tends to wander significantly behind the tow vehicle.
• Metal shavings: If fine metal dust is visible around the shackle bolts, signaling that the bushings have already failed.

Bronze vs. Poly: Choosing Your Bushing Material

Bronze bushings are the choice for those who value extreme longevity and don’t mind a stricter maintenance schedule. Because bronze is a self-lubricating metal, it provides a smooth, consistent pivot point, provided it is kept greased. However, if the grease gun is ignored, bronze will seize and cause damage to the bolts.

Polyurethane bushings are the “set it and forget it” alternative. They are resistant to oil, road salt, and weather, and they don’t require the constant attention that metal bushings demand. While they offer a slightly firmer ride, the trade-off is a massive reduction in the physical labor of trailer maintenance.

Pro Tips for Installation and Maintenance

Always lift the trailer by the frame, never by the axles, to take the load off the suspension when working on these parts. Use a torque wrench for every single bolt; over-tightening can crush bushings, while under-tightening leads to catastrophic failure on the highway. If upgrading to wet bolts, make sure the grease zerks are positioned so they are easily accessible for a grease gun later.

Periodically inspect the torque on shackle nuts, as vibration will eventually loosen them. If the trailer has sat in storage for more than a few months, perform a fresh grease cycle on all wet bolts before heading out. Spending one hour on suspension maintenance before a trip can save days of roadside repairs in the middle of a remote area.

A well-maintained suspension system is the silent partner in every successful road trip, protecting both the trailer and the traveler from the cumulative damage of the road. By swapping out those weak factory components for heavy-duty alternatives, the rig becomes more capable and far more resilient. Take the time to evaluate the specific demands of your travel style, choose the right hardware, and enjoy the peace of mind that comes with a truly road-ready home.
