This insanely strong Center Link has been engineered to maintain all factory alignment specs and steering geometry. This steering system is modeled after the Center Link on the H1 Military Hummer, this is a much stronger design when compared to what's offered from factory on all non Hummer GM HD Trucks. Can be used with GM or aftermarket Idler/Pitman arms. Note: If installing Kryptonite SS Series centerlink on a leveled or lifted truck you may need to install longer sway bar end links depending on how high the torsion bars have been adjusted. We recommend the Kryptonite HD sway bar end links. This kit will only work on trucks that keep the center link in the factory position. If your truck has been lifted make sure the lift kit you have is a spindle style kit not a control arm drop. This steering system is modeled after the Center Link on the H1 Military Hummer, this is a much stronger design when compared to what's offered from factory on all non Hummer GM HD Trucks. KIT INCLUDES: KRYPTONITE SS CENTER LINK AND TIE ROD PACKAGE
