Buying Guide
What load capacity do you need?
Assess the gross vehicle weight rating (GVWR) of your trailer and the expected loads. For 6×12 tandem trailers, options range from light-duty 2000 lb axles to heavy-duty 8000 lb setups. Match your chosen kit to the heaviest intended load and future needs.
Drum vs. electric brakes: which should you choose?
Drum brake kits can be simpler and cost-effective for smaller trailers. Electric brake axles offer consistent stopping power on heavier loads and are easier to upgrade in a complete tandem kit. If you haul frequent or heavy loads, prefer electric brakes for better control.
Hub pattern and spindle compatibility
Most listings use common 6×5.5″ bolt patterns and 1/2-inch wheel studs. Confirm hubface length and spring center measurements to ensure proper fit on your frame. Check spindle type (EZ-Lube vs. non-lubricated) and bearingoil compatibility with your axle model.
Complete kits vs. individual components
Comprehensive kits save sourcing time and ensure compatibility across axles, springs, and fenders. If you already have some components, consider individual parts to customize. Always verify that mounting points align with your trailer’s frame and mounting brackets.
Installation considerations
Look for components with included hardware like U-bolts, brackets, and dust covers, which streamline installation. Ensure you have the correct tools for spring hangers and drum brake assemblies. If uncertain, consult a trailer technician for alignment and braking system checks.
Durability and weather resistance
Industrial-grade springs, sturdy fenders, and rust-resistant finishes help extend service life in outdoor environments. For salt-exposed areas, prioritize corrosion-resistant parts and coatings to reduce maintenance needs.
FAQ
- What is a typical hubface and spring center on a 6×12 tandem? Common hubface measurements are around 71″ to 89″ and spring centers around 58″ to 80″, depending on the axle model. Always measure your trailer before buying.
- Are these kits compatible with Nev-R-Lube or Airstream axles? Some listed items specify compatible 5200-6000 lb lube axles, but not Nev-R-Lube or certain Airstream configurations. Verify axle compatibility before purchase.
- Can I mix drum and electric brake components? Mixing is generally not recommended. Choose a cohesive braking system (drum or electric) for both axles to ensure even braking performance.
- Do these kits include wheels and tires? Some kits include wheel/tire assemblies, while others do not. Review the product features to confirm what is included with your selection.
- Is ABS compatibility necessary for my trailer? If your vehicle system relies on ABS, confirm axle compatibility. Many heavy-duty kits are not listed as ABS compatible.
- What if I don’t know my exact torque requirements? Start with a kit that matches the axle capacity (e.g., 6000 lb or 8000 lb) and bolt pattern. If in doubt, consult a professional to avoid misfit components.
