Block Kits on Andy's Auto Sport TV!
We made a video that gives viewers all the basic information they need to know about lowering a truck! In the video we feature lowering blocks along with other components, and we explain what exactly lowering blocks do and when they're best to use. We also do an installation of a block kit on our project truck. If you want to understand all the basics about lowering a truck, you have to check out this video!

» WHY TO BUY?
Block kits are an extremely easy way to lift or lower your ride, and are probably the most cost-effective to boot. Sierra block kits will normally come with everything you need, including the blocks, U-bolts, washers, and nuts. Keep in mind that it is never advised to stack blocks, so if you need more lift or drop than blocks alone can offer, we suggest also purchasing a set of lifted or lowered Sierra leaf springs.
» DID YOU KNOW?
Block kits effectively lift or lower your vehicle by acting as spacers between your straight axle and leaf springs, using longer U-bolts and new fastening hardware to secure the blocks to your Sierra chassis. Be sure to check your pinion angle after installing a Sierra block kit and, if necessary, install pinion angle shims to correct any misalignment. This will keep your driveline happy and in proper working order for years to come.
