Custom 3" Drop Blocks to lower your 2007-2013 Silverado or Sierra. These incorporate the correct pin location. Unlike using lift blocks that are dangerous since it don't allow your flip to sit correctly on the block. These are specifically made for drop trucks. For these blocks we recommend using McGaughys, Maxtrac, or Cam flip Kits for better results.
