I added a heavier center force fly wheel to my Jeep and ohh my in 4lo i stomp the breaks as hard as I can and it will not stall out. It lugs it a little bit but it won’t stall. If you need a new clutch/fly wheel it is worth the extra money.

How is the center force flywheel "heavier"? And how does that contribute to not being able to stall In 4lo? Did you perform the same text with the oem "lightweight" flywheel?

It "weighs" more.

The added mass of a heavy flywheel creates additional inertia for the crank. It makes it much harder to stop the crank from spinning. Something else is going to slip if you bring it to a dead stop. Likely the clutch, brakes, tires or some combo of the above. The downside is the inverse... it will take more energy to get the crankshaft spinning. So reduced acceleration.

How to say "I really need better brakes" without saying my brakes suck.
 
The opposite, I installed an 8lb flywheel on my Datsun way back in the day and it required a little more throttle and clutch slip to get started but I could make lightning fast shifts and the engine would just rev to match the vehicle speed without inducing a bunch of weight transfer to upset the suspension.

It weighs more then the stock flywheel. Pound for Pound the center force weighs more which creates more inertia therefore keeping it running at lower rpm’s and overpowering the breaks at full lock. And yes before if you used to much break you would stall out even in 4lo.
