Upgrading Leaf Springs on a 2008 Glendale Titanium Tour Series 5th Wheel Trailer

Question

Question:

Here are two photos one is of the sticker on the axle and the other is identifying six leaf springs. You are correct, these are 7000lb axles. This trailer is a 34E39RE Titanium by Glendale. It has a dry weight of 12,079 lbs with the G.V.W.R. Of 15,129 lbs. This trailer is about 11 years old with around 25,000 miles on it. These are the original springs. I tried to measure the springs, unfortunately it has been raining here and hard to get a great reading, however the measurements I got were - total length of spring with weight on from eye to eye is 26 inches, from the mid point around 13.5 inches from the eye end to mid point of the spring. From the top of the lower spring plate straight up to eye end level is around 3.5 inches. The clearance from the bottom of the trailer to the axle is around 2.5 inches. The clearance from the trailer frame and the brake caliper is around 2 inches. I also included a picture of the Morryde block and there is room to lower the rubber block about 1.5 inches to the lowest hole adjustment. I’m assuming that these leaf springs are stretched and with the weight on would seem longer. Hope this helps?

I do have some options for you but I think we need to double check your axle capacity. I looked up the 2008 Glendale Titanium Tour Series 5th Wheel Trailers and the heaviest one I could find (M-36E41TBR) was 12,562 lbs which would be very unlikely to have 8,000 lb axles. The majority of double eye leaf springs max out at 7,000 lbs as well.

Therefore, I recommend that you check the axle tube for the identification sticker. If you can send me a photo of this I would then be able to assist with upgrading the leaf springs. I will also need you to measure the leaf spring you have now using the attached photo. For example, the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles part # e64SR measures to be 24-7/8" long eye to eye.

The correct replacement leaf spring for your trailer is most likely the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles part # e64SR which measures 24-7/8" eye to eye (unloaded). As you mentioned, the loaded leaf spring will measure much longer than the unloaded one and on top of that, they do in fact stretch out over time so I believe the above 24-7/8" option is just what you need. In regards to capacity, double eye leaf springs are hard to come by in a weight capacity over 7,000 lbs because at that point they transition to slipper springs. If you were to upgrade their capacity then the trailer would just be more bouncy and would put additional stress on other components like your tires so this is not what I recommend. Once the new leaf springs are installed, that should then give you more clearance than what you have now as the leaf spring won't compress as much. If you can adjust your equalizers then that is certainly an option as well but forgive me as I am not familiar with the MorRyde system you have. If this still does not give you the lift you need then the only other option we have is to flip the axles with the Dexter Trailer Springs Over-Under Conversion Kit part # K71-385-00 but this will raise the trailer quite a bit (axle diameter+leaf spring stack+spring seat).
