Also I haven't researched Terra flex lifts before but when you buy a lift make sure it comes with all the smaller components to.many lifts out there only come with only the major lift components. Yes the lift your vehicle in this case your jeep, but just remember even the small parts can play a major factor. I also had a Nissan D21 I'm not sure if your familier with the vehicle but it was originally Nissan's little truck before the frontier. Being young and it being my first truck I was dieing to lift it. I didn't have the money for a full lift so instead a went to the local parts house and purchased a $30 block lift. All the lift is, is 2 blocks the size of your choice, and 4 new U-bolts. You place the blocks between the leaf spring and axle. My Nissan had an independent suspension in the front with tortion bars. Add the blocks and tighten the tortion bars to level the truck with the blocks. This was all I needed to lift the truck but in the long run it bound up my cv axles and and my rear drive shaft. Causing damage because I didn't have the smaller parts to realign the axles. I ended up having to replace them which cost me a good penny, and I only added 2 inch blocks. Again I am saying this so you can look for the difference between a good lift, or a lift that will get you by with looks and performance for a short period of time. Many professional off road stores won't even sell or put on some of these online lifts. There is an off road store right down the road from were I live that won't even deal with Ruff Country lifts because they don't give you all the necessary parts with the lift. They say that Ruff Country only sells you the components to lift it. They had a jeep come in with a ruff country lift that had all kinds of issues with proper steering radius, excessive body roll etc. So please be aware of some lifts. BDS Suspensions has excellent lifts with everything you need. You may look them up. Idk your price range but they are very professional. Also when lifting a jeep especially a wrangler be aware of what they call the death wobble. This is when a vehicle hits between 40 mph or above your steering wheel turns right to left uncontrollably. It is not caused by a bad steering stabilizer. Check all your tire rod ends, sway bar, etc. To make sure they are not badly worn. These components cause the "death wobble" not the steering stabilizer. Just so you know. I have a friend that is paralyzed from the "death wobble" he was on the interstate with a jeep wrangler and it began to death wobble causing him to roll 7 times down the road. I wouldn't wish that upon anyone.
