I know I should not have done it from dead stop. 45 mph to 70 mph with fully warmed up Jeep is a better way. They say it is good for the health of the Pentastar so I do it once in a while



The little guy is pretty zippy thanks to 4.88

4.88s are amazing, my little Jeep carries 37s as if they are nothing. Best mod I did to my Jeep
Only real issue I have on the Cherokee with them is the driveshafts don't like how fast they rotate on the highway.

Very nice for rock crawling. Mudding and plowing through deep snow ... I think it's a wash. I can't get wheel speed
 
I run 5.38's with a 4:1 'case and first gear in my tranny is 7.05:1. 151:1 crawl ratio.
You do know you’re supposed to navigate OVER the land and not simply pull it out of the way right?

If my math is right, and not accounting for losses, if the engine puts out 250lb ft your tires are being asked to transmit almost 38,000lb ft of torque 😳

She can drive up hills without me in it. LOL I'm actually running a built AMC 2.5L, and although better than stock, it's still not a powerhouse. I have looked at doing an LS swap for years, as the transmission is a Muncie SM420 (so just a bellhousing change), but it runs great, and bops down the trail just fine.
