New cab suspension system

[CONJIN]

https://youtube.com/shorts/FT4bftNgwcM?si=myUt66HkObyNSk9YMy new cab suspension is working great. I replaced the air bags and bridge with a single motorcycle shock in the center. Came off my old Ducati when I replaced it with an Ohlins shock. The preload fine tunes the height and it's got compression and rebound adjustment. Different spring rates are also available, but the stock one works fine. Note that this isn't a simple DIY. I had to weld lower brackets to the frame crossmember and build the upper mount. Two pieces of wire rope locate the latch plate so that it hits the latch. Been running it for a couple of months and it's quiet and works great. I recently put 53"s on, so this is just one of the mods I've done to run the bigger tires.

Interesting, do you have a drawing or blueprint showing more detail?

No, It's very tight behind the motor, so had to fit it by tack welding the brackets in and seeing if it would work. There is a line coming out of the back of the cylinder head that is in the way, so the shock is a little off center. You can see in this picture, there is a bushing and a leg that pushes on the right side of the shock to keep the plate flat as the hook comes down and engages. I had to make it up as I went.

Interesting setup, is the shock shaft the only thing securing the rear of the cab to the frame now?

Yup. I've had 4 of us in the cab on a trip including offroad and it worked great. It bottomed out a few times offroad, but I think a couple of those hydraulic bump stops would solve that.
