Tera Flex Lift Kits 4 vs. 3

Here is some information about Teraflex lifts for a Jeep Wrangler TJ. A 4 inch lift gets more complicated than a 3 inch lift but does allow 35 inch tires. A 3 inch lift will allow 33x12.5 tires if you get new rims with additional backspacing. For 33x10.5 tire you need to check into backspacing issues. With a 3 inch lift you can use the stock control arms but should get new shocks. The work involved installing the kit is basically replacing the track bar connection in the back with a new bracket and adding length to the rear sway bar linkage. Install new shocks and new springs. Up front you add the springs, relocate the position of the track bar, and install new shocks. Then you need to install a new pitman arm. If you are doing the work yourself, the things to watch out for are: The removal of the stock pitman arm requires a big strong pitman
arm puller. This part is pressed on at the factory and can be very difficult to remove. I have heard of guys that have broken a rental pitman arm puller. It also require a transfer case lowering kit. This is pretty easy to install.
When it's all said and done the ride and look is great. I have been very happy with mine, very low vibration until I bent the rear drive shaft, which force the purchase of new drive line and slip yoke eliminator. When I get my server backup check out more details.
