BILSTEIN 6112 / 8112 Heavy Rate Spring Upgrade Now Available! PN 53-291387

[Battle Born Offroad]

After taking video, going slow-mo and taking measurements to scale, using the 6112 on 650, and getting the factory front bump stops fully compressed,

I will venture a guess that the 650 lb will be necessary even with the 8112 (for higher speed desert, not for anything else).

There is more dampening and bottom out control with the 8112, but the 650 is our preferred spring for it.
