Outer Limits 4x4 Board

hey guys am currently installing 5'' lift in my gq coil cab. after doing the rear's i have noticed the coils are bending backwards slightly toward the shock. nothing serious however would this be caused by the diff rolling back due to the stock length of the lower control arms and the 5'' lift?
i know the stock control arms have a tendency to break so am thinking of purchasing some longer lower arms could somebody direct me to which length would suit as i dont really wish to buy adjustables just longer ones if they will solve my problem! cheers guys

Yep get longer ones. I run Superior ones, I think they are 15mm longer, just give them a buzz and they will be able to supply you with the right length.
