Hey guys
planning to upgrade my diffs to 4.88 gear ratio.
i bet lots of you guys done this on the 4.0 engine because when you got big tires you got much less torque .
so appreciate any comment or help regarding the type or brand of the ring and pinion and what about my current diffs (D35 rear and D30 front). do they support such upgrade!!
thanks for your participation
