If you're looking for the cheapest, poorest fitting transfer case drop with the wrong bolts, look elsewhere. If you actually want something that's quality and fits the way it should, here you go. This is a 1" transfer case drop for 2003-2006 Wrangler TJ's and LJ's. The pucks are 6061 aluminum and are anodized black. Many others for sale are plastic, including many by big name brands. The problem with plastic is when you tighten the bolts you will crush the pucks. Eventually the bolts will get loose and you'll have to tighten them more crushing the pucks further. This will go on forever until the pucks eventually fail and you will never have tight bolts. The bolts may even fall out on you when you're driving. You won't have that problem with these. Tighten them once and you're done. The other thing that makes these pucks better than others is that they have a recess to fit around the nutserts. This means the pucks will rest on the frame, not on the nutsert. Others are flat on both sides which does not allow them to rest on the frame as they should. This will lead to failure of your nutserts which is already a common problem even without adding additional stress to them. You won't have that problem with these. Install them recess side up and flat side down for a perfect fit. The ID of these pucks is also a precise fit to the bolts. Not loose like others on the market. The bolts are Metric 10.9 Class (metric equivalent to Grade 8), hardened, yellow zinc plated for excellent corrosion resistance flange bolts and they are the correct size for 03-06 TJ's and LJ's. The bottom line is if you want the right parts, these are them. If you decide to go with something else, good luck to you. I wouldn't be selling these if there was something else on the market worth using. There are 4 configurations of this kit available, choose the right one for your year and needs: 1987-2002 1" Drop, 2003-2006 1" Drop, 1987-2002 1.5" Drop, 2003-2006 1.5" Drop. A good rule of thumb is: for 2-4" of lift use a 1" drop, for 4-6" of lift use a 1.5" drop.
