Block Kits
What do suspension blocks or lift block kits do?
Lift blocks allow you to raise or lower the suspension (usually rear) to achieve the perfect ride height or stance. This is a popular option when you lift your front, and the rear sags like a ’65 Impala rolling down Crenshaw on switches. Many refer to this as the Cali Lean because, like many vehicle customization trends, it originated in California. In Eastern states, it is also called the Carolina Squat. One thing you need to consider when adding blocks is the potential for axle wrap. Lift blocks increase leverage on the axle, which can cause twisting. Accesspeed customers who purchase 1” to 3” blocks have never reported any issues, which is why we do not sell the large block kits.
