So now everything is wrapping up on the rear, I wanted to share my bump stop logic. I'll define a few things.
Full bump. Both shocks fully compressed, as might happen in whoops, or an airborne situation. Most likely at high speed.
Full flex. Passenger shock completely compressed, driver shock completely extended. Likely to happen Rock crawling, but at slow speeds.
Half flex... I made this up. passenger side fully compressed, driver side half compressed. Likely to happen Rock crawling with enthusiasm. Not full airborne, weight still on the tires, but a sudden harsh impact on only one tire.
I intentionally put my bump stops, inboard of the shocks. So full bump and full flex use pretty close to the same amount of bump stop.
I didn't take a pic of full bump, because it's not needed.
The picture below is of full flex. There is only 3/8" of space between the axle and fully compressed bump stop. Meaning that the 2" travel bump stop will have to compress 1 5/8 to full flex. Because this only happens at lower speeds, I believe this will be adequate. There is still the "emergency" poly disc on the shock shaft that's good for a hard impact or 50, but can split and fall off.
This next pics shows half flex. A likely scenario with aggressive driving. The bump stop is hard against the axle tube at the same time the shock bottoms out. Since this will have much higher shaft speed and momentum, the bump stop will protect the shock.
The green take disc is the contact location of the bump pad, at full bump.
