Front 5100 alternatives

Since it seems that 5100s are out of stock everywhere, can anyone suggest another option?
I already did my rears with a set of 5100s a few months back. I now can't seem to find the fronts anywhere. Everywhere that says they are in stock just ends up putting me on a backorder list. I was hoping to level the truck using the 5100s. My plan was .85 setting with a 1/4 spacer on each side to give me about 1.35 inches of lift. I don't want to go much higher to avoid any vibe issues. I was thinking a set of 4600s and adding a a bigger lift spacer but everything I find is 2 inches plus. I was also thinking 3rd gen setup but most people report a super stiff ride.
