MORryde CRE2-33 CRE3000 Suspension System
The CRE2-33 is designed for tandem axles with a 33-inch wheel base. It offers 3 inches of suspension travel and improved protection from road shock compared with conventional leaf springs. This upgrade is best for trailers that frequently encounter rough roads or speed bumps, where minimizing hitch chatter matters most.
Best for: Owners of mid-length tandem trailers who want a smoother tow and better road shock protection. Why selected: It directly targets passenger comfort and chassis protection, aligning with long-haul or frequent-use RV travelers.
Caution: Installation compatibility should be verified with your current frame and mounting points. Some installations may require additional hardware and alignment checks.
MORryde UO12-016 Heavy Duty Shackle Upgrade Kit
This kit strengthens the undercarriage with thicker shackles, bronze bushings, and greasable bolts. It complements CRE3000 systems or stock setups by reducing wear and maintenance.
Best for: RV owners seeking enhanced durability in the shackle area and lower maintenance over time. Why selected: Upgraded components provide longer life and easier lubrication for smoother operation.
Caution: Compatibility with non-standard leaf springs should be confirmed to ensure proper fit and movement.
Lippert Road Armor Shock-Absorbing Trailer Equalizer
The Road Armor kit uses anti-shock technology to dampen road shock and vibrations. Its single pivoting arm design engages with leaf springs to absorb motion from the leading or trailing springs, offering a robust upgrade when torsion axles are present or avoided.
Best for: Trailer owners wanting a straightforward aftermarket path to reduced chucking and improved ride quality. Why selected: The design targets active dampening of road impact while staying adaptable across common leaf-spring configurations.
Caution: Check the included mounting hardware and ensure the pivoting arm alignment fits your axle spacing and leaf-spring mounting.
SuperSprings Trailer SumoSprings 4-Pack
These progressive polyurethane springs provide up to 1000 lb capacity per axle and reduce sway and body roll. They compress with the weight of the cargo, helping to prevent sag and maintain vehicle level during heavy loads.
Best for: Trailers that regularly carry heavy rear loads or want a maintenance-free upgrade. Why selected: They require no maintenance, adapt to load changes, and improve stability without air systems.
Caution: Do not exceed recommended compression to preserve long-term memory rebound and avoid overloading the springs.
MORryde CRE2-35 CRE3000 Suspension System
The CRE2-35 expands the CRE3000 approach to a 35-inch wheel base, delivering similar benefits with broader compatibility for longer trailers. It emphasizes smoother towing and three inches of suspension travel, reducing road shock exposure.
Best for: Longer tandem-axle trailers needing a larger wheel base upgrade for better stability. Why selected: It extends the CRE3000 line with a similar mechanism for longer rigs, providing consistent performance across lengths.
Caution: Verify wheel base compatibility and chassis clearance due to the increased base length.
Lippert Center Point Air-Ride With Tandem Axle
The Center Point air-ride system dampens road shock and trailer sway effectively. It is designed to be a DIY-friendly upgrade with mounting hardware included to enhance ride quality and braking distance awareness.
Best for: RV owners seeking a premium, ride-damping solution with straightforward installation. Why selected: Air-ride systems typically deliver the most noticeable improvement in ride smoothness and control on varied terrain.
Caution: Air-ride components require proper seal checks and occasional maintenance to preserve performance over time.
Buying Guide: How To Choose The Right Suspension Upgrade
What kind of trailer do you own?
Leaf-spring and torsion setups respond differently to upgrades. If your trailer uses leaf springs, products designed to work with leaf springs, like Road Armor or SumoSprings, are often complementary. For air-ride systems, compatibility with tandem axles matters most.
What load and travel do you expect?
Consider how much cargo you carry and how far you typically travel. Heavy loads increase sag, so progressive springs or air-ride solutions can help maintain level handling and braking control on longer trips.
How important is maintenance?
Maintenance-heavy options require more attention. If you prefer low maintenance, vinyl or polyurethane sumo springs provide stable performance with minimal upkeep.
Installation and fitment considerations
Check wheel base, axle configuration, and mounting points. Some upgrades require additional brackets or alignment checks, especially for longer wheel bases or custom chassis.
Budget and longevity
Higher-end systems like air-ride can be more expensive but deliver significant ride improvements. Progressive springs offer a balance of performance and cost, while basic shackle upgrades add durability at a lower price point.
Practical setup tips
- Plan for professional installation if your trailer’s structure is complex.
- Inspect mounting hardware for corrosion or wear before upgrading.
- Test-drive after installation to confirm improved stability and braking response.
Frequently Asked Questions
- Q: Do suspension upgrades affect braking distance? A: Yes, smoother handling and less sway can improve control and braking effectiveness, especially on uneven roads.
- Q: Can I install these upgrades myself? A: Some can be DIY, but others may require professional mounting depending on trailer design and wheel base.
- Q: Which upgrade is best for heavy loads? A: Progressive springs and air-ride systems commonly provide the most stable support under heavy cargo.
- Q: Will these upgrades fit all trailers? A: Fit varies by axle type, wheel base, and mounting points. Always verify compatibility with your model.
- Q: Do these kits require regular maintenance? A: Some require periodic lubrication or seal checks, while others are maintenance-free like certain polyurethane springs.
- Q: Can I mix and match components? A: In some cases, yes, but it’s best to follow manufacturer compatibility guidance to avoid conflicting motion dynamics.
