Recommended Suspension Upgrade for 2017 Montana 3000RE Tandem Axle Trailer with 16000-lbs GVWR

Question

Question:

I have a 2017 Montana 3000RE tandum axle 5th wheel. GVW is 16000#. I recently had a spring break and the inside of the rig takes a beating when traveling. Can you give me a couple options on what to do smooth out the ride for the trailer?

I recommend using the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks - Tandem 8K, 3-1/2" Axles # RM-2470-2580, which takes the best of both worlds by upgrading your leaf springs and adding a shock system. This will do a great job of reducing the roughness of the ride during travel and also help limit sway, so it's going to smooth out the ride and make it safer.

If you can confirm that you've got a 3-1/2" diameter, 8000-lbs axle this system would work well. If you've got 7k axles you'll want to use the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers - Tandem 7K Trailer Axles # RM-2460-2570.

I've linked a review video we did of this system for you to check out.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Answer 12

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…
