The 1987 RENIX 4.0 made 173 hp (129 kW) and 220 lb·ft (298 N·m) of torque. In 1988 the 4.0 received higher flowing fuel injectors, raising output to 177 hp (132 kW) and 224 lb·ft (304 N·m). In comparison, "this engine made more power than the Ford 302 V8, Chevy 305 V8, Chrysler 318 V8, as well as any of the 6 cylinder engines the Japanese were putting in their trucks... and it had comparable or better fuel economy."[4]
Chrysler bought AMC in 1987 and continued to produce the 4.0 straight six. In 1991 Chrysler redesigned the RENIX engine control computer and raised the intake ports approximately 1/8-inch (3.175 mm) for a better entry radius. Chrysler also enlarged the throttle body and redesigned the intake and exhaust manifolds for more efficiency, and the fuel injectors were once again replaced with higher flowing units. The camshaft profile was also changed. The net result was an engine that made 190 hp (142 kW) and 225 lb·ft (305 N·m) of torque. Badging on most Jeeps equipped with this engine read "4.0 Litre HIGH OUTPUT." The new cam profile combined with altered computer programming eliminated the need for an EGR valve and knock sensor, but made the engine more sensitive to alterations, especially where emissions are concerned.
Small changes were made to the cylinder head for the 1995 model year. In 1996, the engine block was redesigned, and a new strengthened unit was then used. The new block made use of more webbing cast into the block, and a stud girdle for added rigidity of the crankshaft main bearings. The cylinder head was again changed around 1998 to a lower flowing, more emissions-friendly design. Engines installed in 1999 Grand Cherokees carried the Power Tech name, which had been used intermittently in prior years. The name was subsequently passed on to 4.0s in all Jeep models.
Output as of 2004 was 190 hp (142 kW) at 4600 rpm with 230 lb·ft (312 N·m) of torque at 3000 rpm.


gotta love wikipedia.



as for your hockey puck body lift, good luck, cherokee=unibody. coil spacers upfront are sometimes referred to as pucks, although my friend with an 88 wrangler has hockey pucks all the way around for his body lift, literally. a few of them are from me, i used to play haha.


anyways. biggest tires without a lift (since you cant body lift a cherokee) is prolly a 29 if i had to guess, idk what that translates to in metric, but you'll prolly still get a little rubbing with that.


welcome to cf

 

that is awsome i like this site alot great info thanks alot. i bought this jeep with the intention of a fishing hunting camping and trail use i drive it through sum creeks not deep enough to snorkle it and i dont want to lift it to high cause of lifting the canoe/deer but i want a little large more aggressive tire BUFFALO NY winters i bought a brush guard and want to make a roof rack and rocker guards if anyone has good plans ideas or dreams for cheap additons let me here them and thanks agin

 

the biggest tires you can fit would be 235/75/15. maybe 30's but that depends on your jeep and if the suspension sags also you CAN NOT put a body lift on but you could do a buget boast lift with aal and coil spacer up front

 

you can get a small budget lift like 2 inches and fit 31s with just minor trimming and if you search enough you can get the lifts for 100-200 dolars

 

Not quite as tall but a tad wider are 245x70x15's.
