The Timbren Trailer Suspension Enhancement System, part # TTRA1702 is designed for light duty trailers. This system has a weight capacity of 1,000 lbs. You do not want to exceed the trailers weight carrying capacity. Also, this system is for trailers with a suspension system that is in good working order.

If this system meets the weight requirements for your Jayco trailer, then it will fit your trailer if there is room on the frame, above the axle, to drill holes and install the rubber springs. I am including a link to the installation instructions on the Timbren kit that will show you where the springs will install on the trailer frame.

All of our other suspension enhancements are for larger trailers or tandem axle trailers.
