Description

Forget squeaks, rattles, and vibrations—the ReadyLift big lift kits ensure superior performance with smooth rides over all terrain. These leveling and big lift kits feature heavy-duty angled and offset top mount strut extensions that realign the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better manage unsprung mass resulting from the larger wheels and tires on your newly lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings are added, as well as new rear shock extensions to retain the factory performance shocks. With ReadyLift, you don't just get a lift kit, you get peace of mind that your vehicle will excite and delight your senses! Choose the big lift kit for your application needs.

Key features and benefits:

* Heavy-duty, laser cut tabbed and slotted steel construction
* 3/16 in. thick steel plate cross members and skid plate
* Anti-torsion boxed and gusseted plate steel differential drop brackets
* Delivers clearance for increased aftermarket tire sizes—provides an impressive lift, allowing for greater clearance and enhanced off-roading capabilities
* Cast iron knuckles have been engineered to provide ideal geometry for a great ride and handling
* Unique brackets for proper relocation and angle of the front differential
