Thanks Ryan, I will be purchasing soon, researching now to find what is best for our application. I'm not concerned with a stiff/noisy ride at all.. Have been told by a couple of people that the ends wear out quick if drove on the street very much. That would be my only concern. If the uppers are adjusted to change pinion angle, what is the benefit of adjustable lowers? I know I want the relocation brackets, just don't know how necessary the adjustable lowers are.
The rod ends can wear, the time frame will depend on the miles and how much they are used. What wears on the rod end is the lining. The rod ends we use feature a Teflon lining that the spherical ball rides in. This lining is designed to prevent noise and keep the spherical ball lube. Like any wear product this lining will wear over time, the rod end will still preform correctly but may tend to make noise since the lining will thin. Many companies use economy style rod ends with no lining, they are usually noisy from day one and allow the companies to reduce product cost.
Adjustable uppers are used for pinion angle, correct. Adjustable lowers are usually only used for centering the rear end in the wheel wells, aftermarket rear ends that don't sit centered or when more room is needed for larger tires. Other than this the adjustment part of a lower control arm is not needed. The rod ends are beneficial to some applications because allow articulation in the suspension.
If you decide on the relocation brackets I would recommend to look at our lift bars. Our lift bars are basically just a boxed lower control arm with relocation brackets and off set sway bars. The off set sway bar holes are designed to keep the factory sway bar level with the rear end while running the relocation brackets.

I hope this helps!
