It swaps out the factory 1\" rear block for an OEM-style cast iron block, so the net gain is 4\" of rear lift, and new longer U-bolts and hardware come in the box. If your truck sits nose-down after a front leveling kit, or you want a little rake back for towing and hauling, this is the simple fix.\u003c\/p\u003e\u003ch3\u003eWhy it works\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne block, not a stack.\u003c\/strong\u003e A single tall block replaces the factory piece, so you avoid stacked blocks, which may be illegal in some states.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCast iron, OEM-style.\u003c\/strong\u003e The blocks are model-specific cast iron rather than lightweight extrusions, with built-in anti-rotation ears.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs with a leveling kit.\u003c\/strong\u003e ReadyLIFT sells it alongside its GM 6-lug 2.25\" front leveling kit; together they give a mild lifted stance with a slight rake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLifetime warranty.\u003c\/strong\u003e ReadyLIFT covers the kit with its Lifetime Warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003e2014-2018 Chevrolet Silverado and GMC Sierra 1500, 6-lug, 2WD and 4WD.
