Teraflex has put together a great video to help Jeep owners determine the right suspension lift for their Jeep Wrangler JKs. There are a lot of factors that go into choosing the right setup, including tire fitment, ground clearance, performance on various types of terrain, budget, and even just physical appearance. This video outlines the various considerations that go into sorting out the broad selection of suspension options. Other than an idiotic comment about Suzuki Samurais at the 9:12 mark, it is a very well-done video:
Choosing the right suspension is a topic I've discussed before, and while I did not find that Teraflex's options were right for my own Jeep, the information they share in their video will be very helpful in determining what's right for yours. Other Teraflex videos in their series are also worth viewing, such as the one I included in a previous post about choosing the right size tires.
