Zone Offroad F2638 5 Inch Rear Block Kit for 2021+ Ford F-150

The Zone Offroad F2638 is a 5-inch rear lift block kit designed specifically for 2021 and newer Ford F-150 trucks. This rear block kit is engineered to provide the proper lift height to level out your truck's stance when paired with a front suspension lift system.

Key Features:

• 5-inch cast iron lift blocks with durable black e-coating finish
• Tapered design helps improve pinion angle for better driveline geometry
• Replaces factory 1-1/4 inch rear blocks for increased ground clearance
• Eliminates the need to stack lift blocks for desired stance
• Designed to maintain ride quality and handling performance
• Includes longer U-bolts for proper installation

This kit is commonly used as part of Zone Offroad's 6-inch lift systems for 2021-2026 F-150 models, where the 5-inch rear block creates a level to slightly tail-high stance. The cast iron construction ensures durability for both on-road and off-road use, while the tapered design optimizes rear axle pinion angle to maintain proper driveline operation.
