Time to upgrade to 3.73's since my Kenne Bell is handicapped in this Phoenix heat.

Questions:
What can I expect to spend to have this mod done?
Are the axle's pretty strong or do they need replacement too?

Thanks!

 

gears should cost you about 140-260 depending what brand. i reccomend ford racing. install i've heard about 300 bucks for. axles should be fine unless your running slicks, in which case yea upgrade the half shafts and such. good luck.
