Question:
Hello I have a couple questions and wanted to make sure I’m ordering the right parts to upgrade the suspension on my camper. It is a Forest River Wildwood Heritage Glen 370 BL Fifth wheel. I’d like to upgrade to the Moryde all trek 4000 MR89DR , wet bolts MR58ZR , and the X factor cross member MR33WR. I put the part numbers in parentheses.

Hey Jacob! The right parts will depend on the measurements on your trailer. The MORryde ALLTREK 4000 # MR89DR is designed for 33" axle spacing so you will want to grab that measurement. I also recommend looking through their qualifier which I attached below.
The MORryde Suspension Upgrade Kit # MR58ZR is designed for trailers with the Correct Track system installed. Do you have that on your 5th wheel? Assuming you don't, you need to measure the shackle straps to find the right kit. If they're 2-1/4" you need # MR46ZR and for 3-1/8" # MR76ZR.
As long as you do not have the Correct Track, the MORryde X-Factor Crossmember # MR33WR will work with the rest of this setup.
Where are you headed next once you get your suspension upgraded?
