Re-torque U-bolts after the first 500 miles of driving. Never stack rear blocks — this single 2.5\" block replaces any factory block and eliminates the need for illegal block stacking. A professional alignment check is recommended after installation. Lifting the rear of your vehicle raises its center of gravity; exercise appropriate caution when towing or hauling.\u003c\/p\u003e\u003cblockquote\u003e\n\u003cstrong\u003eEngineering Question:\u003c\/strong\u003e Are you adding rear lift to match a front leveling kit, restore towing rake, or both?
