help with helper bags

I lowered my 2001 Silverado dually about four inches in the rear. I used a belltech 3" shackle and removed the overload stack, the middle leaf from the main stack and flipped the bottom leaf (the thick one). I need helper bags. I only have 4" between the bottom of the frame and the axle. What do you guys suggest?

Helper bags mount to the leaf springs not the axle, you'll be fine

any suggestion on brand or kit #?

Air-lift or Firestone is what everybody uses

88275 or 57275 airlift part numbers

I installed airlift helper bags in about 4 hours in my garage. This included swapping sides on the notch so they would fit. Woulda been done in 2 if my shit wasn't bassackwards.....
