Continuing on, you can see as the Gatekeeper has progressed, the front axle and chassis are level and firmly planted to the rock, while the rear axle is tilted and maintaining rear traction. The driver's rear tire is must keep planted or the truck will slide off to the side, thus the articulation of the rear axle divorced from contact with the chassis, other than the top shock mounts and link positions is essential. Interestingly, link risers will slightly limit this due to the increased planar contact distance ( screw to centerline of axle ), but the links themselves can rotate and pivot on the balls and their contact point is forward on the chassis. It's a neat dance when it all works together.

Just remember, when you add a link riser, technically you need to adjust link length. A (sq) + B (sq ) = C (sq ). You added to B, so you need to adjust C to keep the same angle. If not, you will ever so slightly rotate the top of the axle forward, dropping the pinion angle down. Chances of this affecting you on the trail = 0. Is it real = 100. Do we take this far too seriously = 1000.
Don't get me started on tires.
