The ReadyLIFT 26-3104 4" Rear Lift Block Kit is designed specifically for model-specific applications, offering a safe and effective way to lift the rear of your truck. Here are the key features and benefits of this kit:

• Each kit includes two rear blocks, four e-coated u-bolts, and eight nuts and washers, providing everything you need for installation.
• The 4" rear block kit safely lifts the rear of your truck an additional 3" after removing the factory 1" block.
• Made from cast iron based on OEM designs, ensuring durability and strength. Anti-rotation ears are built into the blocks for added stability.
• Compatible with 2014-2018 classic and new body style 6-lug model GM trucks. Newer models with OEM 1.25" blocks can take advantage of the additional 3" of lift, particularly beneficial for towing and hauling when used with a front leveling kit.
• Eliminates the need to stack blocks, which may be illegal in some states, reducing potential safety concerns.
• Helps maintain a slight rake in your truck, ideal for hauling or towing, and works seamlessly with ReadyLIFT Suspension Leveling Kits.
• Comes with ReadyLIFT's Lifetime Warranty for added peace of mind.

Please note the following recommendations from ReadyLIFT:

• ReadyLIFT recommends using the 67-3809 Rear Shock Extension Kit or longer shocks when using a lift block of this height to ensure optimal performance.
• The 3" Rear Block Kit pairs well with ReadyLIFT's GM 6-lug 2.25" front leveling kits, achieving a mild lift stance with a slight rake.

With its durable construction, precise fitment, and compatibility with various truck models, the ReadyLIFT 26-3104 4" Rear Lift Block Kit offers a reliable solution for lifting the rear of your GM truck while maintaining stability and performance.
