i'm wanting ot change gears in my bronco to 4.10 in both rear/front from my 3.55 gears. i want it for towing my big block mustang and a lil more fun off roading. besides, i got 33 inch tires when stock is 31.

how much would it cost me? any 4x4 shops around? any suggestions for places.

 

Talk to Randy at Advanced Four Wheel Drive Systems. Going to a 4:10 will probably require the carrier to be changed also, not sure but I believe 3.90 would be the lowest you could go with the original carrier.

 

will i have to change carriers in both or just hte front? where is this place and any numbers?
