The lift blocks are precision-machined from steel, powder-coated for corrosion resistance, and paired with longer-grade bolts and thicker washers to handle the load and maintain contact with the leaf springs. The package includes two lift blocks and four extended U-bolts sized to replace factory hardware for square leaf spring axles.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these blocks affect my truck’s ride and clearance?\u003c\/h3\u003e\n\u003cp\u003eAdding a 3-inch rear block raises the rear axle, increasing tire clearance and reducing front-to-rear rake. That extra lift can help accommodate taller tires or level the truck when towing or hauling moderate loads. While lift blocks are a durable and economical option, they change rear suspension geometry and may slightly alter handling and ride firmness.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch nominal rear lift for added clearance and a level stance\u003c\/li\u003e\n  \u003cli\u003eIncreased tire fitment room for larger diameter tires\u003c\/li\u003e\n  \u003cli\u003eSimple installation keeps stock springs intact\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and hardware come with the kit?\u003c\/h3\u003e\n\u003cp\u003eThe blocks are CNC-machined steel with a black powder-coat finish to resist rust and wear.
