The center is locked and the front is spinning until some point where both tires are deeply stuck...it is definitely working under normal/medium load. Does the 4 pinion make it perform differently, meaning it will handle slippage better than before? or it’s just make more reliable?
My current hight:
Rear about 21.5 inch (auxiliary tank almost empty)
Front 20.5 inch
May add spacer to 2863 to help with sag/or go with 2864. As for 2866, it’s not going to help if you have load.
With 2864, add 320+ lbs and rear should go down 1 inch. I 🤔
I have been running 2863 for years but after adding drawers the LC is sagging a little bit . I tried 2866 (progressive.. I think) and it feels great without load almost close to stock ride.
The spring rate is a key player here..the minute you cross the spring load rate the rear hight goes down 1...
