So I am thinking of getting an aftermarket front bumper, and I am curious about sagging that a front bumper might cause up there. I currently only have spacers up there, and in the rear I have shackles and AAL. Can I put coils up front without changing out the shocks up there to counterbalance the weight? If I do need to change the shocks, any suggestions (Just got 9100 Ranchos for rear) for for front replacement? Please feel free to make any suggestions on how to keep the front end up with a new bumper...I am open to any of them.
