HCLLPS Aluminum 16Pcs Kit
Material: Aluminum alloy designed for wear resistance, high-temperature tolerance, and long-term durability. The kit provides 16 bushings with precise 9/16″ I.D., 11/16″ O.D., and 1-3/4″ length. A direct replacement for part number 722106, aimed at trailer axles and double-eye leaf springs.
Best for: Heavy-duty trailer owners who expect prolonged service life under demanding loads and harsh environments. It suits users replacing worn bushings on frequent-haul trailers or fleet maintenance programs.
Limitations: Aluminum bushings can be less forgiving in extremely misaligned systems; verify fitment with your exact axle and spring configuration before ordering.
TYHI Aluminum 16Pcs Kit
Material: High-strength aluminum alloy engineered for rigidity and wear resistance. Includes 16 bushings sized 9/16″ ID, 11/16″ OD, and 1-3/4″ length, designed as a direct replacement for 722106 and suitable for double-eye springs.
Best for: Trailer operators needing a complete, one-shot replacement set to overhaul a double-eye leaf-spring system and axle equators, with emphasis on robust performance under heavy towing.
Limitations: Confirm that the kit matches your axle width and spring type to avoid mismatch during installation.
HCLLPS Nylon 16Pcs Kit
Material: Nylon bushings offering good wear resistance and corrosion resistance, with the same 9/16″ ID, 11/16″ OD, and 1-3/4″ length. This kit is designed for universal fit with double-eye leaf springs and equalizers.
Best for: Buyers seeking a quieter material option with reliable wear properties, useful in boats, flatbed trailers, or general trailer maintenance where nylon suits the environment.
Limitations: Nylon may be less rigid than aluminum under extreme load; check compatibility with your trailer’s load profile before replacement.
Dunzy Brass 16Pcs Kit
Material: Brass bushings offering corrosion resistance and solid wear performance over time. Includes 16 bushings sized 9/16″ ID, 11/16″ OD, and 1-3/4″ length, suitable for trailer axle replacement and double-eye springs.
Best for: Those needing a durable brass alternative with strong heat and wear resistance in harsh environments or where brass metallurgy is preferred for compatibility with certain treatments.
Limitations: Brass may be heavier and slightly pricier; verify the bushing’s fit and whether brass is appropriate for your specific trailer system.
GREPSPUD Nylon 8Pcs Kit
Material: Nylon bushings with 9/16″ ID, 11/16″ OD, and 1-3/4″ length. Designed as a universal fit for double-eye springs and equalizers, compatible with trailer leaf spring bushing replacements.
Best for: Quick, cost-effective maintenance tasks or smaller trailer setups where nylon provides adequate wear resistance without added weight.
Limitations: A smaller kit size (8 pieces) may require additional purchases for larger trailer systems or future replacements.
Buying Guide: Key Considerations For Aluminum Leaf Spring Bushings
What material should you choose?
Aluminum alloy bushings deliver high wear resistance, rigidity, and heat tolerance, making them suitable for demanding towing conditions. Nylon provides quieter operation and corrosion resistance with lighter weight. Brass offers durability and specific compatibility in some environments. Consider environment, load, and maintenance frequency when selecting.
What sizing is essential?
Most trailer bushings follow a standard 9/16″ inner diameter, 11/16″ outer diameter, and 1-3/4″ length for double-eye springs. Verify your axle width and spring spec before ordering to avoid improper fitment. Accurate sizing ensures stable operation and minimizes wear on the leaf spring system.
Direct replacement vs. universal fit
Direct replacement kits are designed to match part numbers (e.g., 722106) and fit precisely, simplifying installation. Universal-fit nylon options offer flexibility across different trailers but may require extra checks for compatibility.
Durability and operating conditions
Aluminum bushings excel under high heat and heavy-duty workloads. If your trailer operates in harsh weather or salt exposure, choose corrosion-resistant alloys or coated variants. For lighter-duty or quieter operation, nylon might be sufficient and easier on components nearby.
Installation considerations
Follow vehicle manufacturer guidelines and torque specs. Ensure the bushings are seated correctly and that surrounding components (eye plates, shackles, and equalizers) are in good condition. Improper installation can lead to misalignment and accelerated wear.
Compatibility checks
Always verify with the Amazon Confirmed Fit or vehicle-specific compatibility notes. Scan for notes about engine, model year, and trim to avoid incompatible parts.
Maintenance expectations
Regular inspection every 6–12 months or after heavy use can detect wear, cracking, or deformation early. Replace bushings in matched sets to maintain balanced performance across the axle and leaf-spring system.

Frequently Asked Questions
- What size are standard trailer leaf spring bushings? Answer: Common sizes are 9/16″ inner diameter, 11/16″ outer diameter, and 1-3/4″ length, designed for double-eye springs.
- Which material lasts longest under heavy use? Answer: Aluminum alloy generally offers superior wear resistance and heat tolerance for demanding towing conditions.
- Do I need to replace all bushings at the same time? Answer: Replacing in matched sets helps maintain balanced performance and stability across the axle.
- How can I verify fitment before buying? Answer: Check the Amazon Confirmed Fit notes and compare your trailer’s axle and spring specifications to the kit dimensions.
- Can nylon bushings replace aluminum ones? Answer: Yes in many cases, but consider load, noise, and environmental exposure; nylon can wear differently than aluminum.
- Is a shorter or longer length important? Answer: Length should match your spring’s engagement and the bushing seat; incorrect length can cause misalignment and wear.
