IHC Suspension lowering kits work with custom control arms to maintain factory ride quality and alignment specifications. IHC 4/6 is adjustable to 5/7. How is that achieved? The front lowers using 5” lower control arms that can be adjusted to 4” by sliding 2 IHC spacers under the strut and lower control arms. Upper control arms are included and necessary for alignment. IHC control arms come with new ball joints, bushing and links. IHC flip kit is used to lower 6” and drop shocks are included. By removing stock shackles and adding 2” lowering shackles, setting it on 2nd hole will set it at 7”. C notch is not required at 7” but is recommended.
