Buying Guide: Key Considerations
What material should I choose?
- Nylon bushings offer low friction, corrosion resistance, and durability for most marine trailers.
- Brass bushings are durable and heat resistant, good in some heavy-use scenarios but may require more attention to salt exposure.
What size do I need?
- Most common is 9/16″ inner diameter for double-eye springs; verify your existing bushings before purchasing.
- Length is typically 1-3/4″; confirm with your springs or equalizers to ensure a proper fit.
Should I buy a kit or individual bushings?
- Kits are convenient for multiple axles or future maintenance. Individual bushings are suitable for spot repairs.
- Consider the quantity you need based on the number of axles and potential spare components.
What about compatibility?
- Check whether the kit is designed for the trailer model or the specific axle setup (double-eye, equalizers, etc.).
- Review whether the kit includes hardware (bolts, nuts) or only bushings to ensure full replacement coverage.
