A block lift (often referred to as a budget lift) is a modification that is similar to a body lift in the way it works, but used in a different location. Block lifts are used to provide more room between the body and axle of a vehicle for larger tires. A block lift consists of either extended spring isolators or blocks that are inserted between a vehicles axle and spring, or a spring and the vehicles body. This type of lift is often preferred due to the affordability and ease of installation.
