Guide-Recommendation
Evaluation & Recommendation
This U-bolt is ideal for:
- Trailer owners using 45mm square axles with 60mm wide leaf springs
- Heavy-duty applications including tandem trailers, tradie rigs, or marine trailers
- Customers needing stronger clamping force with 5/8″ bolts
It may not be suitable for:
- Round axle trailers – use round U-bolts instead
- Axles over 45mm width
Installation Advice:
- Use anti-seize on threads before tightening in wet environments
- Torque nuts evenly to avoid uneven spring compression
- Recheck nut tightness after initial use or first tow
