the 456 with 33's bring it pretty close to stock. i want nothing more from mine. i have a superlift tru speed box to get the speedo right, and i'd probably research the plastic speedo gear more if i were doing that again although the box i have works ok. i get between 14 and 18 mpg, but that's pretty standard.

94 yj 456gears, detroit locker and 30 spline axles out back, 33" bfgs
