when buying gears is there anything else that i need to purchase along with the gears. im planning on getting 4:10's

 

nope should come with the shims

 

well, i wish it were that simple, i had to buy a few more things in addition to that,,

you should get the rear end rebuild kit if your car has anywhere over 45-50K miles (check mustangtuning.com, its the 8.8 rebuild kit, about 90 bucks i believe)

next you'll need the speedometer recalibrator,,,depending on where you get this it will run 90-140 or so, i bought mine on sale from ninosport.com for 85

umm, depending on who does it, they might want rear end diff. fluid, probably two bottles, 5 bucks a piece at any auto store... i think that was all i bought,,

good luck, youre going to freaking crap the first time youre 'allowed' to get on it

 

Well oviously you need fluid but I have never put a rebuild kit in any of my cars, you do need the speedo calibrated thou
