Where did you buy the leaf liners and U bolt eliminators?I netted 4.5" using this setup:
Stock main
Slightly cut main (it is full length with the eyes just barely cutoff. It partially wraps up at each end by about 1/2")
Stock 2nd
Cut 2nd (exactly halfway between 2 and 3 stock lengths)
Stock 3rd
Cut 3rd (exactly halfway between 3 and 4 stock lengths)
Stock 4th
Also, a 1.25" shackle, HD shackle relocation brackets (???"), 1/2" lift u-bolt eliminator kit. Also running full length Teflon double lipped leaf liners between all leaves.
I haven't added a cut 4th in yet but I might to help I increase the load capacity a bit when I'm towing a trailer.
I will not run any other leaf pack again other the this setup. It is nice and flat so you get a lot of droop (as opposed to the limited droop you get on a very arched/stiff pack). My load capacity is a lot better then the soft stock setup and with the liners, it is not squeaky and it flexes very smoothly through the whole range of the leaf. hands down way better for an all around daily driver/expedition/camping rig then any aftermarket pack. Maybe if you are pre-running or hardcore rock crawling you'd want something different.
Thanks!
