Morryde SRE4000 vs CRE300 or...Pin Box???
Hi, I am considering an upgrade to smooth out the ride of my trailer. I have an Open Range trailer that is about 13k loaded and has Lippert equalizers. Truck is a Ram 3500. Ride is pretty level. ...

I installed Lippert Equa-Flex equalizers 6 months after our small 9140 lb. fifth wheel was new in 2013. We never felt a difference. The MORryde CRE 3000 is in the same class so I personally would not bother with it. Last year we installed a MORryde pin box, and I would estimate that it reduced the chucking by 50% or more—not gone but a big improvement. Two weeks ago we had the MORryde SRE4000 installed. Wow, what a difference—we no longer feel the trailer back there (at least when it hits bumps/holes). However, we still feel the truck tires hit bumps and holes, and that alone is fairly rough. Now we want a tow vehicle with an air ride suspension.
The best bang for the buck is the pin box because you can purchase it on line for reasonable bucks and install it yourself if you are comfortable with heavy tools and a torque wrench. Be sure to torque the bolts in the pin box itself, not just the mounting bolts. Mine came below torque spec. Annual torquing should be done anyway. However, I recommend the SRE4000 first (don’t waste time and $ with the CRE3000) because the difference it made for us was so profound (and because it will be easier on your trailer in addition to less chucking. The cost will vary depending on tire clearance. The SRE4000 requires 4” of tire clearance because it allows more up and down axle movement. The installation adds 1” itself but double check with MORryde to be sure on clearance. So if riser tubes or a sub-frame need to be added, that raises the cost of the SRE4000.
