Our Lift Blocks can NOT be stacked and are designed to replace the 1.5" OEM Blocks on 4WD models, and help you achieve the advertised additional rear lift.We are proud to introduce our NEW US Patent Pending Steel Lift Blocks for lifting the rear of your vehicle. Using Heavy Duty GMAW Seam and Fillet Welding Processes we machined each lift block from 1-Piece CNC Formed Steel Frame and reinforced it's structure with 1/4" Thick CNC Plasma Cut Support Walls for maximum strength and stability.These Heavy Duty lift blocks are fabricated with Built-in Bump Stop Plates to help maintain proper suspension travel and geometry, as close to factory specification as possible. This eliminates the risk of bottoming out & improves the quality of your ride while protecting your vehicle’s suspension.Our 4", 4.5" and 5" Lift Blocks are engineered and designed with a Built-In Taper to help keep your differential's pinion angle as close to factory specification as possible. This helps eliminate the possibility of driveline vibration occurring due to misaligned driveshaft/differential angles, and keeps your u-joints and driveline bearings lasting longer.NOTES:An alignment is always recommended after altering the height of your vehicle.
