Amount of Spring Deflection of Timbren Alxe-Less Suspension # A20RS440


Hi, I am looking for a little bit of information regarding your axle-less suspension if that is ok. Am I right in thinking the rubber spring also acts as the damper, or do these need additional damping? I see they are rated for weight so can I assume this is per pair? so for example your A20RS440 is rated for 2000 lbs so if I were to use 4 of these for a twin axle trailer would this be suitable for use up to 4000 lbs? Also could you tell me the amount of travel the suspension has from static position ie + or - 2, and if this static position is with the hub centre at 2.5 from the chassis mount as in the dimensions diagram? Thanks in advance for any help you can provide.

You are correct, the Aeon spring does indeed function as a dampener, and should not need additional dampening.

Each unit is rated at a 1000 lb capacity, so two sets or four units would provide a 4000 lb capacity. The 2-5/8 inch dimension shown is the static position, but this exact dimension will depend on the construction of your trailer and how heavy it is.

The engineering folks at Timbren tell me that the springs are capable of 2-1/2 inches of travel or deflection.
