HCLLPS Aluminum Alloy 16Pcs Leaf Spring Bushings
HCLLPS offers a 16-piece aluminum alloy bushing kit designed for 9/16″ inner diameter and 1-3/4″ length with 11/16″ outer diameter. This configuration targets trailer axles using double-eye springs and matches part 722106. The aluminum alloy provides wear and heat resistance for long-term durability in demanding conditions. Best for buyers who want a direct, heavy-duty aluminum replacement and a generous quantity for multiple maintenance cycles. Caution: verify your bushing inner diameter and overall spring width to ensure a precise fit with your specific trailer model.
TYHI Aluminum Alloy 16Pcs Bushing Kit
TYHI provides a complete 16-piece aluminum bushing kit with the same 9/16″ ID, 11/16″ OD, and 1-3/4″ length. It is marketed as a direct replacement for part 722106 and emphasizes high-strength aluminum alloy for rigidity and wear resistance under heavy towing. Best for buyers seeking a robust aluminum option that supports full spring and axle replacement in one purchase. Limitation: confirm compatibility with your trailer’s double-eye springs and ensure the mounting hardware aligns with the kit’s dimensions.
GREPSPUD Nylon 8Pcs Trailer Bushings
GREPSPUD offers 8 nylon bushings sized for 9/16″ ID, 11/16″ OD, and 1-3/4″ length, intended for universal use with trailer double-eye springs and equalizers. Nylon provides light-to-moderate wear resistance and corrosion resistance, making this a good option for average-use trailers or where weight savings matter. Choose this if you prefer a non-metallic, low-friction material that can still handle routine maintenance. Caution: nylon may wear faster under extreme loads compared with high-grade aluminum or brass in some heavy-duty towing scenarios.
Dunzy Brass 16Pcs Trailer Leaf Spring Bushings
Dunzy supplies a 16-piece brass bushing kit for trailer axles, offering high wear resistance and temperature tolerance. Brass can resist corrosion in certain environments and provides a solid replacement option where aluminum isn’t ideal. This kit is best for buyers who want an alternative to aluminum and need reliable performance in warmer climates or where brass compatibility is a factor. Limitation: brass is heavier and may not suit all trailers; verify your equipment’s allowances for brass bushings and ensure correct fit by diameter and length.
KLMHT Nylon 4 Pack Replacement Bushings
KLMHT offers a 4-pack of nylon bushings designed to fit 9/16″ ID and 1-3/4″ length in a 4-piece set. They emphasize nylon material for wear and corrosion resistance, suitable for budget-friendly maintenance. Choose this if you’re performing routine single-axle maintenance and want a cost-effective nylon option. Caveat: smaller kit size may require additional purchases for full trailer maintenance.
Buying Guide: Key Considerations For Aluminum Leaf Spring Bushings
- Material choice: Aluminum provides high rigidity and heat resistance, making it a good all-around choice for heavy-duty applications. Nylon offers lighter weight and corrosion resistance but may wear faster under heavy loads. Brass can be a middle ground with good wear properties but added weight.
- Dimension accuracy: Confirm 9/16″ inner diameter, 11/16″ outer diameter, and 1-3/4″ length. These are common specs for 722106 replacements; mismatches can cause poor seating or misalignment.
- Compatibility: Double-eye springs, axles, and equalizers vary by trailer model. Use the Amazon “Confirmed Fit” or verify with your equipment’s specifications before ordering.
- Quantity needs: For multi-axle trailers or spare parts stocking, kits with 16 pieces reduce replacement frequency. Smaller kits suit light or occasional maintenance.
- Application scenarios: Aluminum bushings excel in heavy-duty towing and high-heat environments; nylon is beneficial for light-duty or where weight reduction matters. Brass is durable in certain climates and conditions.
Quick fit-check questions
- Will the bushing’s inner diameter fit around the existing pin or bolt size?
- Does the bushing length align with the current spring and shackle configuration?
- Is the trailer’s spring width 1-3/4″ wide, and are the eyes double-eye type?
- Is there any exposure to high heat or corrosive environments that would favor brass or aluminum?
FAQ
- What is the main difference between aluminum and nylon leaf spring bushings?
- How do I know if a kit fits my trailer?
- Should I replace all bushings at once?
- Are aluminum bushings suitable for all climates?
- Can I mix different materials in the same axle?
- What should I do before buying?
Aluminum bushings offer greater rigidity, heat resistance, and durability for heavy-duty use, while nylon bushings are lighter, corrosion-resistant, and often cheaper for routine maintenance.
Check the inner diameter (ID), outer diameter (OD), and length against your current bushings and confirm compatibility with your trailer model and spring type (double-eye or equalizers).
Replacing the complete set ensures balanced performance and reduces the likelihood of uneven wear. For older trailers, inspecting each bushing prior to replacement is prudent.
Yes, aluminum bushings generally perform well in varied climates, but verify corrosion risks in your environment and consider coatings or alloys designed for outdoor use.
Mixing materials is not recommended as different wear rates and tolerances can cause uneven movement and potential misalignment.
Compare all specs, confirm fit with your trailer’s model, and consider whether you need a full kit or smaller replacements to align with your maintenance plan.
