Many will tell you that you need to convert your YJ to coil springs. A lot of TJ guys will agree. We won’t tell you not to coil-convert your YJ. We will tell you to think about it since conversions can run upwards of several thousand dollars. Sure, the kits work great and offer much improved ride, articulation, and often handling, but unless you’ve already got a ton of money in things like body armor, engine swap, axles, and so forth, it might be cheaper to start with a TJ if coils are what you are after. That said, companies such as Superlift, Rock Krawler, GenRight Off Road, T&T Customs, and Pro Comp all offer coil-conversion kits that will sooth your TJ envy.
