Question:
I have a 2019 Montana 3811ms. I want to buy the 3 X factor braces. I also need the angle pieces that get welded between the hangar brackets. What do I need?

Hey David welcome back! I am not sure what you mean by angled pieces that get welded to the hanger. We have two types of X-Factor Crossmembers and one of them attaches directly to your frame hangers with included brackets and hardware.
The MORryde X-Factor Crossmember item # MR33WR attach to standard frame hangers that look like item # E4139. This is most likely what you need.
The MORryde X-Factor Crossmember item # MR99ZR works with LRE, RE, or TRE Leaf Spring Suspension.
I have linked the installation instructions below along with a couple of videos we have made getting these crossmembers installed. I recommend taking a look at them and comparing them to your Keystone Montana's suspension. If you have any additional questions feel free to email me directly or comment below.
