Question:
I have a 2020 Puma 253FBSs fifth wheel I would like to upgrade the suspension on. I am thinking the MR87ZR equalizer and the MR46ZR upgrade kit. Here are my measurements: 35 inch wheel base, 58 3/4 inch Hanger spread, equalizer is 6 inches long and 4 inches high, shackles are 2 1/4 inches long, 6000 lb axels. Are the above equalizer and upgrade kit recommended for my measurements? Thank you.

Hey Bill, thanks for reaching out. The MORryde Suspension Upgrade Kit # MR46ZR is exactly correct for you. It comes with the 2-1/4" HD shackles, bronze bushings and wet bolts, all of which will be a nice upgrade for your 5th wheel. With proper care these suspension components will last the life of the trailer.
The equalizer is going to be a bit more tricky. The new equalizer needs to be identical in size to the current one. There is a small amount of tolerance like 1/2" or less. Any more than this can throw your suspension out of center and cause things to not line up properly. That said, the # MR87ZR equalizer is 6-1/2" long and only 3-1/4" tall and in my opinion this is not within the tolerance for an equalizer. There is a chance it may work but it may also throw things out of center and cause all sorts of headache. I am sorry to say that we do not offer a shock absorbing equalizer that matches your measurements. The only option would be a direct replacement part # TREQ310 which is exactly 6" long and 4" tall so this is what I recommend going with.
Adding the MORryde shackle kit will still be a nice upgrade for your suspension and will allow things to ride more smoothly. I will be here if you have any other questions just let me know.
