Instructions & Info

This kit can be adjusted to 11″ or 12″. You will need Torsion Keys #52310 (sold separately), to raise up the front. You will also need the Rear Lift Shim Kit #52361 (sold separately), to raise the rear up.

If running this kit at the 12″ position, we highly recommend using Upper Control Arms #52314 (sold separately) to help with bump stop clearance issues.

Over-sized tires and heavier wheels can cause premature wear on factory and aftermarket components like ball joints, bushings, tie-rod ends, wheel bearings, idlers arms, drive-lines, etc…  You may need to replace / install new components sooner than factory recommendations based on the wheels and tires you choose. Please note that the heavier and wider wheels and tires combined with aggressive driving (off-road and on highways) will cause more wear on ALL moving parts, factory and aftermarket. Especially when vehicle is in 4wd or Auto-4wd / AWD modes. 

Spindles and u-bolts are shipped with protective coating on surface. This allows them to be delivered to you without rust. We recommend you clean and paint the parts before you install, to protect against any future rust. Remember, spindles and u-bolts are bare metal. And will rust without paint.
