For your 2015 Rockwood Freedom 1940 LTD, I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Regular Tires - 3,500 lbs # ASR35HDS05. This will give you the suspension components integrated into the axle-less spindles. With this kit, I recommend the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA along with the Trailer Hub and Drum Assembly - 3,500-lb E-Z Lube Axles - 10" Diameter - 5 on 4-1/2 # AKHD-545-35-EZ-K.

This will give you the suspension as well as the lift for using larger wheels for increased clearance. Let me know if you'd like further recommendations. This system only requires a 2 inch square tube be used between the spindles into the integrated holes for support. This will increase your ground clearance under the trailer as well.

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 12

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…
