Zone Offroad D1306 3-Inch Rear Box Lift Block Kit with Overload

The Zone Offroad D1306 is a 3-inch rear box-style lift block kit designed for trucks equipped with factory overload leaf springs. This rear lift block kit delivers a clean, no-compromise lift at the rear axle, raising ride height by a full 3 inches to improve stance and tire clearance without modifying the front suspension.

Key Features:

• 3-inch rear lift via a high-strength fabricated box-style lift block
• Engineered specifically for trucks with factory overload springs — select this kit if your truck is overload-equipped
• Includes extended U-bolts to properly secure the block to the axle and leaf spring pack
• Restores or enhances rear ride height for a level or slightly tail-high stance
• Compatible with factory wheels and tires; allows fitment of larger aftermarket tires
• No cutting or welding required for installation
• Backed by Zone Offroad's limited lifetime warranty

Zone Offroad products are built in the USA and engineered for durability and precise fitment. Professional installation is recommended. This kit is the overload-specific variant — trucks without factory overload springs require a different part number.
