With your TJ you will need a 8,000 pound winch. Smittybilt makes a cheap one for around $300. The most trusted brand is Warn. One of their 8,000 pound model is going for around $540 or something like that. Shop around and try to find the best deal.
Any time. The super winch is a great deal that jeepaddon has. Myself, I have the smittybilt xrc8 winch with the synthyic line. I've used it only like 5 times in the past year since I bought it. It has worked great!
