Jeep 94’ 2.5L ?

The 2.5 in the Jeep should be the AMC 2.5. Not the most powerful thing in the world, but should be adequate. The most effective way to boost the performance of any Jeep is through the axle gearing. The 2.5 should have 4.10 gears, but that was for a 28"-29" tire originally. Looks like it has 31" tires on it now so a re-gear is in order. (as a point of comparison my DD is an 05 LJ Rubicon which originally had 4.10 gears and 31" tires. I now run a 33.5" tire and the difference by swapping to 4.56 gears was like night and day). Also, from the picture it looks like some mis-guided soul tried to lift the Jeep with a longer shackle. For safety sake, do something else.
