Buyer’s Guide: What to Consider

To pick the right 4 lug trailer axle, focus on hub face width, spring center, load capacity, and spindle type. These factors ensure a proper fit and safe towing.

• Hub Face Width: Measure from the bottom of one wheel stud to the other. This determines your trailer's track width and stability.
• Spring Center Distance: The distance between spring seats affects how the axle aligns with your trailer frame. Match it to your existing suspension.
• Load Capacity: All axles here are rated for 2000 lbs. Ensure your trailer's gross weight does not exceed this limit for safe towing.
• Spindle Type: Hub kits fit straight or tapered spindles. Check your axle's spindle diameter and shape before purchasing a hub kit.
• Installation Requirements: Some axles require welding brackets. Hub kits may need bearing installation. Choose based on your DIY skills and tools.

Conclusion

Choosing the right 4 lug trailer axle depends on your trailer’s specific dimensions and your installation preferences. For a complete axle beam, Thomletha offers three hub face options to match your track width. If you need just hubs, the Redants kit is pre-assembled for convenience, while the Saree kit fits two spindle sizes for versatility.

Measure your trailer’s spring center and hub face carefully before ordering. With the right axle or hub kit, you’ll enjoy a reliable and safe towing experience for years to come.
