When getting gears is it a good idea to get a bearing kit? I'm going to be getting 4:10's very soon and I remember someone telling me to get a bearing kit. But on mustangtuning it says to get it if you have over 60 k miles and i only have 35 k. Also what size bearing kit do you buy when getting 4:10's? 8.8's or 7.5's? Oh yea and by the way I have a 99 GT

 

i'd get it if i was you... just one more part that wont wear out as fast if its new.

 

what size?

 

oh, you want the 8.8"... you have the 8.8" rear end... the V6 mustangs have the 7.5" rear end.

 

ok say if i get those gears and the sct-xcal2 i can only tune my car once unless i pay for more tunes?

 

nah, that programmer will allow you to adjust and it will hold 3 different tunes. it comes with 3 tunes i think actually? but its best to fine tune on a dyno for more power. its kinda like an adjustable hand-held tuner.

 

ok so say i have the 4:10 gears and i adjust it and say i messed up doing something and i plug it back in it that counted as 2 tunes? Also say then i get a new part can i program the part in my self to the tuner or do i have to send it back for them to program it? And also where does it plug into? lol. sorry for all of the questions.

 

you tune it yourself, you dont really need it tuned for you unless you have a bad *** n/a, nitrous, or a blower/turbo. it plugs into the OBDII port under the driver side dash on the right side. if you messed up on that tune you can go back to that tune and correct it. you can tune for the gear size, fuel injector size, MAF size, having no cat's, engine rev limiter, top speed limiter, air/fuel ratio, spark advance/retard... there are probably more things too.....

 

Question ~ Does the motive bearing kit work with the FRPP 4.10 gears? or is there a special FRPP Bearing Kit.

 

Does anyone know?
