Hey David. We've got a couple of options depending on how thick the axles are on your 2019 Keystone Montana 3811ms. I have listed them below:
3-1/2" Diameter Axles - Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks item # RM-2470-2580
3" Diameter Axles - Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks item # RM-2460-2580
Both of these systems come with the Roadmaster slipper spring kits and nitrogen-charged shocks that help to eliminate trailer bouncing, chucking, and purposing.
Do you know how thick your Keystone Montana's axles are?
You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.
