1999-2024 GMC 1500 2.25" Rear Block Kit (66-3002)

If you need to add a slight rake back into your pickup, the last thing you should be doing is stacking blocks; this can cause severe damage and is incredibly unsafe, not to mention illegal in some places. ReadyLift offers a wide variety of rear lift blocks so you can safely add the appropriate amount of height to your truck.  Based on OEM designs and made from cast iron, these blocks are durable, easy to install, and make a great tow package upgrade.
