Need to know some things about 37's
So my dad is planning on getting a JK too.
He's basically going to copy paste everything in my signature. Only difference is, he wants the 4.5" lift with 37's..
So what I need to know, is what additional parts need to be ordered on top of everything in my signature to make his ride absolutely perfect?
He's not very concerned with price, so mention the very expensive goodies too
Thanks

He will want to reinforce the front axle with axle C gussets and either sleeves or a truss. (You should consider at least the axle C gussets with your 35s.) If you buy Teraflex gussets and sleeves, you shouldn't require modification to the AEV steering bracket. You should both consider weld-on lower control arm skids if you offroad your JKs. JKS is one manufacturer that sells them.
If he has an automatic, he will want 5.38 gears. 5.13s with an automatic and 37s is lethargic.
If he offroads his JK using his lockers, he will want chromoly axle shafts front and rear to reduce the frequency of breaking shafts.
He will want a Superchips Flashpaq instead of the ProCal. The ProCal is just a calibration tool and does not tune the motor for increased performance. He will want the power increase from the Flashpaq.
His ride would improve with a Teraflex long arm suspension. However, it will still be very good with the AEV 4.5" Premium and all JKS arms.
He will want different wheels then you. The AEV Pintlers have 4.7" backspacing, which is too much for 37s unless you significantly adjust your steering stops. He should consider 4.5" or less backspacing.
If he wants a softer, smoother ride, he will want to avoid load range E tires and stay with load range D or Cs.
"Perfect ride" is very subjective and depends on the type of terrain he will most commonly drive.
If money is not a concern, he should do a 5.7L Hemi conversion at the same time. If he does the Hemi, he will want 5.13 gears instead of 5.38s with an automatic.

My suggestion is just to build his JK like mine. I think 37's are excessive for the driving he'll be doing.
5.7 Hemi... I wish.. There's nowhere to do a conversion here and I'd rather not attempt it on my own. I could always ship my JK to AEV for a conversion.. at the same price of buying another JK
But to be honest, I'd much rather put in a diesel than a Hemi.
Don't get me wrong, I LOVE the Hemi's and think having a 5.7L or 6.1L engine would be amazing. But it's just not practical for what I use my JK for haha
Thanks for the info, was very helpful
