Cognito 4"/6" Non-torsion bar drop Front Suspension Lift Kit for 2011-2019 Chevrolet and GMC 2500HD / 3500HD 2WD trucks.
When set to the 4" height the vehicle will retain the stock (original) tie rod angles. When adjusted to the 6" height there will be a slight angle increase at the tie rods.
This kit is a "non-torsion bar drop" design which keeps the torsion bars in their original location rather than hanging down under the chassis. Front track width is increased by 5/8" per side in order to retain proper caster settings and functional electronic stabilizing control (if StabiliTrak equipped).
We've incorporated a front skid plate that ties the included Cognito front and rear cross members together for added rigidity.
This kit also includes our patented Cognito Pitman and Idler Arm Support Kit--a must-have upgrade that corrects a design flaw in Chevy and GMC truck steering systems.
Sway bar end links and all required mounting hardware are included, and all steel bracketry is finished in semi-gloss black powder coating.
This kit is not a complete lift package, so it does not include shocks or rear suspension lift components.
