Happy to help Mike, thanks for reaching out!

Most common upgrades for the suspension on a 2025 Grand Design Imagine XLS 22RK:

Roadmaster Comfort Ride Shock Absorber System # RM-2460-2570 – This system adds shock absorbers to your existing leaf spring suspension, helping reduce bouncing, chucking, and road shock. It improves towing stability and helps protect the trailer, suspension components, and interior from excessive vibration.

MORryde AllTrek 4000 Equalizers # MR27ZR – The AllTrek replaces your factory equalizers with rubber cushioned equalizers that absorb road shock before it's transferred to the trailer. It's a popular upgrade that improves ride quality while reducing stress on the suspension and frame.

You mentioned crossmembers, MORryde X-Factor # MR33WR would be a great choice. It installs between the center spring hangers to reinforce the trailer frame, helping reduce hanger flex and frame twist. It's an excellent addition if you frequently tow on rough roads or simply want to strengthen the suspension mounting points. The X-Factor works very well with the MORryde AllTrek suspension upgrades.

Could you let me know the axle capacity on the 22RK? That wat I confirm these parts are the correct fit for your trailer.

Also, let me know what you're hoping to improve with the suspension upgrade. For example, are you experiencing excessive bouncing, chucking, trailer sway, or are you mainly looking to strengthen the suspension and frame

@MikeO the Roadmaster Comfort Ride Shock Absorber System # RM-2460-2570 and the MORryde X-Factor Crossmember # MR33WR are both great choices. For the MORryde Shock Absorbing Equalizers, you'll select those based off the center on center distance between outer shackle bolt holes. Equalizers w/ 8" spacing MORryde Shock Absorbing Equalizers for Tandem Axle Trailers w/ 35" Wheelbase - 8K # MR27ZR Equalizers w/ 6-1/2" spacing MORryde Shock Absorbing Equalizers for Tandem Axle Trailers w/ 33" Wheelbase - 8K # MR87ZR Let me know if you have any questions.

@MikeO I have a 2024 Grand Design Imagine Aim 15RB single axle trailer. The crossmember went in without a hitch but the standard GD hangar was too wide for the stabilizing bolt (the one that has the spacers with it) to fit. I just left the bolt off and it seems to be doing fine but you might want to account for that.

@MikeO I bought some x braces, really seem to strengthen up the axle area. I added the rear when I had a spring hanger break. Had it welded & reinforced with the "v" pieces, and then added the x brace. I added the front one also but had to get the drop down brackets due to a gray water drain. I recommend them. Next I am installing the comfort ride system, but will retain the front & rear x braces. I don't believe you can do the center one.

I added the crossmembers to the front and back of the axles on my 44ft Redwood 5th wheel about 1 year ago. I had a crossmember in-between the axles when I purchased it with the LRE 4100 Redwood MORryde shock and could not be happier with the ride. So far, almost 10,000 miles and everything is still straight and true. Very happy with the additional crossmembers.
