2013 sport 3.21

Well after picking a new 4 dr manual 2013 on clearance the paper on the window says next generation dana 44 3.21.........damn....being its the stronger 3.6.......would 4.56 gearing be a great choice for 37in mtr kevlars on stock rims with 2 inch spacers......4.88 seems too low......but I also want to trail in mud with only the dana 30 c gussets and truss installed....no sleeves.....its my dd for now......I have the 2.5bb with cut fenders soon ...pinch seems and clearance will be addressed wen tires arrive.....no serious offroading until I save for the 4.5 bds......so 4.56?thanks jko.

For a manual, 3.6L 4.56 will be fine. You don't need 2" spacers though (don't know if you can find them). Synergy makes some 1.75" ones
