Recommended Timbren 3,500 Axle-Less System with 4 Inch Lift Spindle for Lance Trailer

Question:

Hi Guys-I want to raise my 2012 Lance 1575 trailer 4inch and the specs on that trailer for empty weight is approximatley 2500#s. Full gross is 3500#s. Timbren is suggesting their 3500HD which probably means new brakes and hubs and then wheels and tires-yikes. Seems to me that the 3500 Timbren axle-less 4inch lift will work fine even for boondocking/off-road and I believe and therefore why reaching out to the brain trust at etrailer that my existing electric brakes, hubs, wheels and tires will bolt up. If the 3500HD-4inch lift is a better call which electric brakes and hubs do I need and which model number of the 3500HD would I want to order so that I have the right offset for new wheels and tires so that I dont extend tires outside of fender flairs-or can all sorts of offsets be found for wheels to adjust for the either 6inch or 8inch frame to hub face spacing on the Timbren axle sets and their specs? You can see its a complex question and the last guy I talked to at Timbren knew less about the subject than I-and hopefully you guys! Thanks

The only real difference between the Timbren Heavy-Duty Axle-Less Trailer Suspension with 4" Lift Spindle - 3,500 # ASR35HDS05 and the standard Timbren # ASR3500S06 is that the Heavy-Duty model features a larger spindle that would accommodate larger hubs and wheels.

I am not sure why Timbren would have suggested the Heavy-Duty model for your application but the standard Timbren # ASR3500S06 features the capacity you need, the lift you are wanting, and would allow you to retain the use of your existing hubs and brake assemblies. Because of this I recommend the standard set and don't really see a need for the Heavy-Duty option.

With the hub installed on the spindle there will be 6 inches from the hub face to the frame of the trailer. You can use this information to determine if you will have enough clearance for your particular tires and wheels. I have also attached a diagram to assist.
