good luck with the install man.i hope it's a quiet one.

rampant racing 07-26-2011 09:35 PM

did you go with the motive gears or something better?not trying to be rude but they are known for being noisy.

rampant racing 07-28-2011 12:08 PM

well what's the news on the gear install? good i hope.your probably out enjoying the xtra ooomph.

gears are in...definitely an improvement over stock 3.31
lots of go power from a standing start
we got some gear whine going on, but not irritating at all...tech figures it may go away after a break-in period
motiv 4.10 + Ford trak lok + aluminum cover

next is to re:calibrate speedometer with my SCT tuner...speedo off by about 20k

Good news. As far as hearing gear whine, that just means you need louder exhaust. :tup

LOL maybe!!
I actually don't mind the whine so much.

got the tuner out and reclaibrated my 4.10's + added the Bama tune
she's got some get up and go now for sure!

did a 50 mile run over to my daughter's place and back...got some vibration going on...at 60 mph. need to take a ride without the wife to see if it goes away at higher speed.

I assume there is some sort of "break in period" for the gear set...any suggestiions? around town, she's a rocket.
