Will Timbren Silent Ride Suspension Cause Issues with Single Point Contact on Tandem Axle Trailer

Question

Question:

Question: Can the Silent-Ride System be added to an existing travel trailer with tandem axles currently using a Lippert equalizer? It looks as if the axles come off the frame and the Silent-Ride system attaches between the original axle points. If so, should I be concerned about the frame taking the whole load at one point each side rather than being shared with two axles? Thanks

That is an excellent question, and while I can see where you're coming from, the Timbren Silent Ride Suspension # TSR7000T05 is designed to maintain the integrity of the trailer frame so you won't have any issues with the frame resting on this single point as opposed to 3 points on either side of the trailer.
