The stroker gives all its power in the low end. While the 4.0 give it more mid. Strokers are not high reving motor compared to the 4.0. If you looking for a motor for running trails/rocks where your crawling its a great motor but if you looking for deep mud/sand where you need to rev it to clean the tires this wouldn't be a good choice.

Well my problem us she sees highway driving. She sees a lot of snow wheeling. A lot of sand. Mud. But also we do a lot of crawling and stuff too. We see almost every type of wheeling there is and with only 33s and 4.10s she revs quite high

Gotcha my jeep runs 2400rpm ish at 80MPH so I dont rev it high and all my wheeling is done in trails and rocks so the stroker is a good choice for me.

Aren't the stroker kits incredibly expensive compared to dropping in a larger more common motor like a 5L ford or a 5.7 chevy? While you don't have to go putting in adapters and new mounts and all of that, I've been quoted upwards of $6000-7000 to stoke a 4.0L. That seems incredibly high for what you're getting.

???? your joking right? the 4.0 isnt a "high revving" motor to begin with... a stroker does not limit you in anyway... a 4.6 will rev out to 5100-5200 rpms all day long.... the 4.7 stroker has been running the baja since the 4.0 was born, and those engines live near the rev limiter...

the beauty of a stroker is you dont have to rev it out, but it doesnt mean you cant.

are you building a race engine or a DD, at the shop I have built 2 long block 4.6's for 2500 bucks OTD.

the problem is when you get into forged h-beams or i-beams and forged cranks and all this other jazz. If your not going to be banging it off a 6k rev limiter there is no need to go forged everything. a 258 crank and rods, and some forged speed pro's or KB and that engine will live just as long as a 4.0. Its all in the balance.

He's got the stroker. And its all about gearing. I can put mine to about 85 but that's practically redlining it
