yj gearing question

[90txXJ]

my dad got a wrangler and it has no top end, i checked the engine and it runns like a top but there is no top end. i think is his gearing 3.08 with 33s. is there any other way to get more power or is this normal, it is a 5 speed.


i dont really know of any other good forums so i wanted to ask yall.

Would this be a 4.2 carbed engine?

everything there should hold - if he has the 4.0L

No such thing as 4.0 carb. What year? Yes, he needs gears. 33's with 3.08's will make 5th pretty much useless under 80 mph. 4th will be marginal under 65 mph. If its carbed, its a 4.2 and they typically feel like they hit a wall at @3000 rpm.

Huh. If its a '90 or older its a 4.2 with a carb + high gears + big tires = slow. Time to regear.
