Trailer Axle Replacement for 2015 KZ RV Spree Escape 200 with 65-1/2 Inch Spring Centers


I bought a 2015 KZ RV Spree Escape 200. It has a Gross Weight of 3500 lbs. The axle appear bent as the wheel lean inboard at the top. It appears the Spring center measurement is 65 1/2. Please advise how the current suspension would be rated. What would the current axle weight likely be, and what would the springs weight rating be. Would they both be 3500 lbs or would the axle be 3500 lbs and the springs less? Also, what could I used to replace them? I would want to increase the capacity because having water in the tanks and an extra propane tank already appear to bring the weight to about 3900 lbs. I am having trouble determining what new axle and new springs to include weight rating should be used. My springs length from eye to eye is 26. Thank you!

It does sound like you either have a bent axle since your wheels are pointing inward at the top. It sounds like an overloading issue caused this because with water you stated your weight is well above the max capacity of 3,500 lbs. The axle and springs would be rated for the same capacities so springs and axle need replaced.

You can increase the axle capacity, but that doesn't account for the other components like the frame, the coupler, springs, etc. that may also be rated for that 3,500 lbs capacity so you want to make sure other components are rated/compatible for a higher weight as well.

The spring centers at 65-1/2 inches is not a standard spacing, so your best option is to use the Timbren Axle-Less system that will also replace your suspension so you don't need to worry about that upgrade. As long as the frame can handle more weight an axle upgrade will work. The next size up is the Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs # ASR5200S01 and then you will simply use a 2 inch square bar not included to span the width and connect to the integrated holes in the assemblies.

With that spindle you will use the Dexter Trailer Hub and Drum Assembly - 5,200-lb and 6,000-lb E-Z Lube Axles - 12" - 6 on 5-1/2 # 8-201-9UC3-EZ, brake assemblies # AKEBRK-7-SA and then compatible wheel and tires like # AC225R6SMEQ that have a great load rating of 2,830 lbs at 80 psi and speed rating of 81 mph to meet and exceed your new axle capacity. This combination also comes with 2 years roadside assistance for more peace of mind.
