You finally got your truck lifted and it looks great, but...now you've got drive line vibration. If you bought your kit from Jack-it, you probably won't have this problem, but if you do, chances are some minor shimming will correct it. Degree shims come in several different degree angles so you can get the proper correction for your particular need. If you are not sure how much correction you'll need, give us a call and we'll try to help you. Shims are available in Aluminum, Cast Iron, or Steel. Although the steel shims are a little more costly, they're less likely to come loose or even fall out.
