5. Maintenance
The CURT Helux Coil-Spring 5th Wheel Pin Box features a virtually maintenance-free design. Unlike traditional air systems that require regular monitoring and adjustment of air pressure, the coil spring system provides dependable performance without ongoing upkeep.
Recommended Maintenance Practices:
- Periodic Visual Inspection: Regularly inspect the pin box for any signs of wear, damage, loose fasteners, or corrosion. Pay close attention to the coil springs, shock absorbers, and mounting points.
- Cleanliness: Keep the pin box free from excessive dirt, mud, and road debris. A simple wash with soap and water can help prevent buildup.
- Fastener Check: Periodically check all mounting bolts and nuts to ensure they remain properly torqued. Refer to your RV or pin box installation guide for specific torque specifications.
- Lubrication: While the coil spring system itself is maintenance-free, any moving pivot points or the kingpin may require occasional lubrication as per standard towing equipment practices. Consult your RV manual or a qualified technician for specific lubrication recommendations.
Should you notice any unusual noises, excessive movement, or visible damage, discontinue use and have the pin box inspected by a qualified service professional.
