Block kits are an extremely easy way to lift or lower your ride, and are probably the most cost-effective to boot. 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 leaf springs.
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 chassis. Be sure to check your pinion angle after installing a 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.
Q: Does a block kit lower the front or the rear of a truck/SUV?
A: Block kits are used to lower the rear of a truck only. Due to the fact that the front and rear suspension on trucks are different (in order to accommodate the load of cargo a truck bed is built to carry), blocks kits are not applicable to front suspension of any truck. A common form of front suspension on trucks is a set of coil springs for example, and block kits do not work with coil springs.

Q: Is a block kit only used on certain vehicles?
A: Block kits are only used on vehicles that utilize leaf springs in their suspension set-up. Block kits are used in conjunction with leaf springs.
