The CST CSK-G23-3 4" Stage 3 Suspension System With 2.0 Emulsion Shocks will allow you to add larger wheels and tires to your Silverado or Sierra 2500HD/3500HD 4WD. This suspension system features welded & laser cut front spindles and front subframe to keep the steering geometry safe while giving the truck addition ground clearance. The rear gets a set of lift blocks for additional height without sacrificing towing capacity while the front and rear get the DIRT Series 2.0 Emulsion Shocks on all 4 corners for superior handling on and off-road. This American made suspension system also includes a skid plate for added protection and a complete hardware kit with all the components needed for installation.
