YllJYK SHK-3A-SB-LE Replacement Kit
Designed for triple-axle trailers, this kit includes four weld-on 1.5-inch tall hangers and four weld-on 2.5-inch tall hangers, plus 16 shackle straps, 4 equalizers, and a hardware set. It facilitates installation of 1-3/4 inch double-eye springs on a single axle and supports a 2000–7000 lbs range per axle. Note that springs and U-bolts are not included, so plan for compatible components when assembling the system. This kit is suitable for trailers, RVs, and some trucks needing reliable hanger replacements.
maXpeedingrods Complete Trailer Hanger Kit
This hanger kit is designed for 2″ wide slipper springs and is weldable directly to the trailer frame, offering robust support for heavy-duty applications. Constructed from high-quality Q235 steel, the kit emphasizes strength, plasticity, and solid welding performance. It is well-suited for tandem or triple-axle trailers that use slipper springs and require a direct-frame mounting solution, enabling reliable load distribution and vibration control.
LLANNDER Heavy Duty Greaseable Shackle Kit
The LLANNDER shackle kit features 3.125″ shackles designed for tandem and triple-axle trailers, with forged bolts achieving high tensile strength and Cu-based powder metallurgy bushings for wear resistance and damping. The kit supports upgraded suspension systems and aims to reduce sway and improve stability during towing, with notes on proper bolt tightening and compatibility with common double-eye springs.
Generic Triple Axle Equalizer Kit 3.5K-8K
This equalizer kit is designed for triple-axle trailers with 2″ wide slipper springs, supporting a broad range of 3.5K-8K axle ratings. It is compatible with major brands like Dexter and Lippert and provides a practical option for improving load transfer and trailer stability in combination with slipper springs. Installation requires suitable hardware and alignment with your axle and spring setup.
Generic Triple Axle Equalizer Kit 3.5K-8K (Dexter)
This triple-axle equalizer kit uses Swan-shaped equalizers for Dexter-style axles and is designed to be used with 2″ wide slipper springs. The kit aims to improve stability across the axle by balancing load distribution and reducing sway, suitable for upgraded suspension configurations and vehicles requiring precise alignment of equalizer components.
MORryde CRE3-33 Suspension System
The MORryde CRE3-33 system provides triple-axle suspension with 3 inches of travel and smoother towing compared to conventional leaf-spring setups. It offers enhanced protection against road shock and improved control during cornering and load transfer, making it a strong option for RVs and trailers that demand a refined ride and dependable performance on varied terrains.
Buying Guide
Key considerations when selecting a triple axle trailer suspension kit:
- Compatibility: Confirm spring type (double-eye vs. slipper), width (2″ or 1.75″), and axle rating (K lbs range). Some kits are axle- or brand-specific (Dexter, Lippert).
- Mounting method: Weld-on hangers require welding capability and time; bolt-on options offer easier retrofits but may need brackets or adapters.
- Material and durability: Look for heat-treated steel or high-grade alloys; bushings should resist wear and provide damping.
- Maintenance: Greaseable shackles and readily accessible fasteners simplify inspection and service intervals.
- Installation considerations: Ensure available space, frame geometry, and alignment with existing leaf springs and U-bolts. Some kits assume additional components (springs, U-bolts) are supplied separately.
- Ride quality vs. cost: Systems with added travel or damping (like MORryde) often deliver smoother towing but may come at higher upfront cost.
- Intended use: Heavier loads and frequent towing through rough roads benefit from stiffer hangers and robust equalizers, while light-duty setups prioritize ease of installation and weight savings.
Choosing the right triple-axle suspension kit involves balancing compatibility, durability, and installation practicality against your towing needs and maintenance plans. Consider how each option aligns with your trailer type, typical loads, and driving conditions to optimize stability and longevity.
