Lift with sumosprings?

So I've figured out my front lift, going with 885 and 5100's. I have a question for the back, currently I have stock leaf back with sumosprings installed. If I add a leaf or get a new pack this will raise my frame away from my sumo's and I'll lose the use of them right? How do I lift the rear and still use my sumo's? I have a '13 base SR5, 6 speed, 4.0, DCSB on stock steal 16's. Would like to run tall and somewhat skinny tires.

 

I've read that unloaded there will be slight gap between the Sumo and upper perch, but once you put load in it will make contact and function as it's intended. That is my plan - 3 leaf AAL and then the Sumo's kick in when I need them.

 

Mine was sagging so bad when I installed the sumo's it raised my back up 1/2", so the ride is just a bit stiffer but it doesn't bottom out going over the railroad tracks anymore. That pic is with 800lb in the bed and 2.5" squat

 

I'm pretty much sold on the sumosprings. It looks like it would be a good fix for sagging solution for hauling.

 

They do make the ride noticeably stiffer and the old shocks are not up to par to handle the extra spring they add. I think I'll get the 5100's then I'll have them for the lift latter.

 

i believe the sumosprings are progressive so it'll ride stiffer as it gets compressed more. But since you have old shocks its more than likely it's contributing to having the sumosprings support more of the weight.
