NBS Chevy/GMC IHC 5/7 Suspension Lowering Kit

Drop your NBS suspension with this 5/7 lowering kit for 1999-2006 and 2007 Classic Chevrolet and GMC Silverado/Sierra from IHC Suspension! This kit includes everything you need to overhaul worn out suspension components while also lowering your ride height 5 inches in the front and 7 inches in the back. IHC separates themselves from other lowering kits on the market with key differentiating features such as control arms that fix the driver side lean issue these trucks have, and flip kits with the correct pinion angle built in. To resolve the notorious leaning issue that 1999-2006 trucks have where they sit 1" lower on the driver side (which becomes more apparent after you lower the suspension), IHC adjusted the spring pocket on the driver control arm so it's not as deep as the passenger side. This results in all four corners sitting level after installation.

IHC Suspension Quality

All IHC suspension parts are fiber laser cut, CNC bent, and robotically welded for precision fitment. 1/4" thick steel plate is used in both the C-notch and flip kit that's durable and built to last. Each upper and lower control arm is outfitted with polyurethane bushings for max performance, low maintenance, and long service life. On top of that, IHC Suspension components are manufactured in the USA out of their Texas warehouse with a lifetime warranty on all metal components for unmatched quality and peace of mind.
