IHC Suspension is excited to announce our best-selling lowering kit for 2014-2018 GM 1500 ext/crew cabs. IHC 4/6 lowering kit. IHC Suspension coming from the service/installation side understood the challenges that other kits were not solving.

• Standard Upper Control arms for camber correction. (No additional parts needed like camber/caster bushing or offset ball joints to align)
• IHC control arms run Delrin bushing for maximum performance, extended bushing life, and minimal maintenance.
• IHC Flip kit has the correct pinion angle built in so no need to use pinion shims.
• NO C NOTCH REQUIRED
• MADE IN USA!
• Manufactured in TEXAS!
• Lifetime warranty on all metal parts!

IHC Suspension 4/6 lowering kit consists of Upper and lower control arms. You achieve the drop with the lower control arm and the upper is for alignment correction. Spacers are included to adjust front control arms from 4” to 5” with our purchasing any more parts. Shorter sway bar links are included for better sway bar angle. The rear consists of a flip kit with the correct pinion angle built-in, so no pinion shims are needed. Nitrogen drop shocks included and 1” lift shackles to keep the truck level. C notch is not required but may be recommended if roads are rough. Helper bag kit is another option IHC recommends to prevent bottoming out.
