Essential Considerations Before Upgrading Trailer Suspension
Upgrading your trailer’s suspension system is often driven by a desire for a smoother towing experience and better protection for both the trailer structure and its contents. Anyone who frequently tows, hauls delicate or valuable cargo, or simply travels on less-than-perfect road surfaces is an ideal candidate for such an upgrade. Conversely, someone who only uses a small utility trailer occasionally for short trips, or for whom ride quality isn’t a primary concern, might find a full suspension overhaul excessive or unnecessary. When considering an upgrade, potential buyers should think about their trailer’s axle configuration (is it tandem?), the specific wheelbase measurement needed for compatible parts, the weight capacity of the suspension system, the complexity of installation, the materials used for durability, and the expected level of improvement in ride quality and trailer longevity. Understanding your specific towing needs and trailer specifications is crucial before diving into the market for suspension solutions.

Introducing the MORryde AllTrek 4000 System
The MORryde TG2-33 – AllTrek 4000 Suspension Upgrade – Tandem Axle, 33” Wheelbase Kit is essentially a replacement for the standard metal equalizer used in leaf spring tandem axle setups. Its core promise is to deliver a significantly smoother, more controlled ride by utilizing rubber springs to absorb road shock and vibration more effectively than traditional components. The kit typically includes the rubber equalizers, heavy-duty bushings, and necessary hardware for installation on trailers with a 33-inch bolt hole spacing between the equalizer pivot points. Compared to the factory-installed equalizers found on many trailers, which are often made of stamped steel and utilize flimsy plastic bushings, the AllTrek 4000 represents a substantial upgrade in material quality and engineering designed for better performance and durability. This specific AllTrek 4000 system is intended for owners of tandem axle trailers where the equalizer measures 33 inches center-to-center on the bolt holes, particularly those looking to mitigate the harshness associated with standard leaf spring setups. It may not be suitable for trailers with different axle configurations (single, triple) or different equalizer lengths.
Pros:
* Dramatically improves ride smoothness.
* Reduces stress and vibration on the trailer structure and contents.
* Constructed with durable materials compared to stock components.
* Can potentially provide a slight increase in trailer height.
* Enhances overall towing comfort and reduces fatigue.
Cons:
* Installation can be challenging and may require multiple people.
* Higher upfront cost compared to basic replacement equalizers.
* One user reported a component shearing prematurely.
* Requires verifying specific trailer measurements (33” wheelbase).
In-Depth Look at What Sets the AllTrek 4000 Apart
The heart of the MORryde AllTrek 4000 Suspension Upgrade lies in its innovative use of rubber as the primary suspension medium within the equalizer mechanism. Traditional leaf spring equalizers simply pivot, attempting to distribute weight between the axles but doing little to absorb vertical shock. They transfer much of the impact from road imperfections directly into the trailer frame. The AllTrek 4000 replaces this pivot with a complex rubber spring system. As one axle encounters a bump, the rubber compresses and rebounds, dissipating much of that energy within the equalizer itself rather than transmitting it forcefully through the trailer chassis. This results in a far smoother ride, minimizing the jarring and bouncing commonly associated with trailer towing.
This rubber absorption is perhaps the most significant benefit of the AllTrek 4000 system. Think of driving over railroad tracks or expansion joints on the highway; with a stock setup, you feel every jolt reverberate through the tow vehicle and see the trailer visibly shudder. With the AllTrek 4000, these impacts are substantially muted. This isn’t just about passenger comfort in the tow vehicle; it has critical implications for the trailer’s longevity and the safety of its cargo. Less vibration means less stress on welds, less loosening of fasteners, less cracking of interior walls or cabinets, and less potential for appliances or electronics to be rattled to death. For those hauling sensitive equipment, fragile goods, or simply wanting to preserve the condition of their RV interior, the value of this smoother ride is immense. It transforms the towing experience from a bone-rattling endurance test into something noticeably more refined and less stressful.
Beyond the core function of shock absorption, the AllTrek 4000 suspension upgrade is built with durability in mind. Many stock equalizers use inexpensive plastic or nylon bushings that wear out quickly, leading to sloppy movement, increased noise, and accelerated wear on other suspension components. The AllTrek 4000 utilizes heavy-duty components designed to withstand the rigors of thousands of miles on varying road surfaces. This robust construction contributes to the system’s longevity and reliability. While installation can be labor-intensive, often requiring jacking the trailer and working with heavy components (and potentially a second person, as some users note), the improved build quality means less frequent maintenance and replacement down the road compared to cheap factory parts. One user specifically pointed out the “utter garbage” OEM setup with thin plastic bushings, highlighting just how much of an upgrade the build quality of the AllTrek 4000 represents in this regard.
The specific “Tandem Axle, 33” Wheelbase” designation is crucial. This MORryde kit is engineered to fit tandem axle trailers where the equalizers have 33 inches between the mounting bolts. This isn’t a universal kit, emphasizing the need to measure your existing setup before purchasing. The benefit of this specificity is ensuring a proper fit and the intended performance. The design is optimized for the load distribution and pivot geometry of this common tandem axle configuration, ensuring the rubber springs compress and extend correctly under typical towing conditions.
An interesting side effect some users have noted is a slight increase in trailer height after installation. One reviewer mentioned a 1.5-inch lift over their stock Lippert equalizers. While not the primary function of the AllTrek 4000, this modest lift can be beneficial for trailers that sit low, providing improved ground clearance when navigating uneven campsites, steep driveways, or rough trails. It’s a potential bonus feature that adds a layer of practicality for certain towing scenarios.
Furthermore, the reduced wear isn’t limited to the trailer structure. A smoother ride also translates to less abuse on the tires and the axles themselves. Constant harsh impacts can accelerate tire wear and put undue stress on axle components and wheel bearings. By absorbing much of this shock, the AllTrek 4000 helps protect these critical parts, potentially extending their lifespan and reducing maintenance costs over the long term. While the initial investment in the AllTrek 4000 suspension upgrade might seem significant, the potential savings on repairs, tire replacement, and reduced damage to cargo or interior components can easily justify the cost over years of use. It’s an investment in the overall health and longevity of your trailer.
The difference in performance is often described dramatically by users. Phrases like “100 times better than the stock setup” or “rides so smooth on the California back roads now” paint a clear picture of the transformation this system provides. While installation difficulty is a disadvantage, requiring significant effort and possibly specialized tools or help, the consensus among many users is that the payoff in ride quality and reduced stress on the trailer is well worth the effort and expense. Even under heavy loads (like a 14,000 Lb trailer mentioned by one user), the system effectively compresses the rubber, indicating it’s actively working to absorb impacts, leaving sufficient travel for handling bumps. The reported durability over a full camping season and thousands of kilometers, with no sagging and components remaining in great shape, further supports the claim of this being a robust and effective upgrade.
What Trailer Owners Are Saying (Real-World Feedback)
Having looked through feedback from others who’ve installed this upgrade, the sentiment is overwhelmingly positive regarding the performance boost. Many users express amazement at the transformation, noting “what a difference” it makes, leading to a “smooth and comfortable ride.” Owners frequently mention the drastic improvement over the “garbage” stock setups, particularly highlighting the use of flimsy plastic bushings in OEM components as a key weakness the AllTrek 4000 addresses. Some users appreciate the potential for a slight lift, finding it helpful. While one user reported a part failure relatively early, this seems to be an anomaly among numerous positive experiences praising the system’s durability and effectiveness over extended use, even under significant load.
