The truck is completely stock, with a 1" body lift and 31/10.5/15 Kumho M/Ts on factory steelies. If I can maintain at least 65mph reliably I'd be happy. When I got it, it was meant for a parts buggy, but it's way too nice. Had a bad head or gasket,I didn't even check which. Just ordered a new NJV one. It ran mint. But 50-55mph topped it out and it struggled, it was tired. Ive never been in one, so I didn't know if maybe that's just the way they were performance wise, Suzuki Samurai-ish. I love the things,they grow on me daily, a nice break from the jeep scene. But I really want it to be a little more practical, mph wise.
