Will installing FJ Cruiser coil springs on my stock 10' 4R SR5 4x4 lift my ride up at all ? I am looking to get 2" (MAXIMUM) lift front and rear, keeping the stock rake. Correct me if I'm wrong, but if I add 2 adjustable Billies to the front, and 2 non-adj to the rear with the FJ springs, this may be accomplished ?
