Re: General Jeep Questions
Hmm ok, so as long as I change the gears to match any mods I do, then this
engine is good enough? I will only be using it as a "for fun" daily driver in the summer just for light inner-city cruising around with the top half off. The rest of the time it'll be used for mud offroading - nothing TOO serious but I do need some power to get out of the thicker stuff. Are there any differences between the 4's of the CJ/YJ/TJ line? The 4cyl TJ's from '97 to '99 seem to go pretty cheap relatively speaking. I've seen some around 100 to 120km for 8-9000.

I don't need any *crazy* mods but I'd like to put a 2.5" skyjacker spring lift and throw some 33" BFG MT's on. Should I change the gears for this? Is this a bad lift idea? Anything you'd recommend? |

I can still use 5th, but it costs gas, about 5 mpg better without it. Off road we have low range so never have issues. As mentioned, 'I' had a big truck spring shop do my lift. They do not sell gold plated springs like the 4x4 shops do or use platinum tools like the specialty shops also use. :-) Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's - Gone to the rust pile...
