My first TJ was a 2001 Sport (factory ordered). It remained stock for only two weeks, at which point it got the Teraflex 4" lift with long arms and 35" tires. I chose this lift due to positive feedback from numerous owners, plus a magazine lift comparison where they praised the ride and performance of that kit. I was extremely happy with how it rode on all surfaces and how it performed off the pavement. Here are some old, tiny photos:
Two years later I had to sell that TJ. Eventually, I owned TJ #2, and then TJ #3 and then TJ #4. All were lifted to various extents, but none had 4" coils or long arms.
Now I own TJ #5. I bought it stock, and I was planning for this one to be my keeper. For that reason, I knew I would have to recreate my original setup. A few months ago (in August), it finally became a reality. This time around I also installed a 1" body lift (plus a lot of other stuff that isn't related to the topic at hand):
Since 2001, Teraflex has seriously upgraded their long arms. Now referred to as Monster Arms, they are considerably beefier than the original design. The ride and performance are both still great, and I am completely satisfied with this setup.
