I have a 1996 dodge diesel 3.54 gears in rear dana 70 with new 37x13.50r20 with 12in wide rims. egt now cruise at 1000 or a little more. if i put 4.10 in the rear should it drop egts a lot or not enough to be worth spending the money on. timing is at *16 degrees also if i added another 2 degrees would it help. i want to keep this 7in lift with this tire combo bad.

 

Huge help. Consider 4.56's
