  Great gear for a 4 valve daily driver!

  I have these gears installed on my 98 cobra. I installed them in my shop with new bearing set and new clutch pack. These gears have been very easy to deal with on the highway and pull hard from 1st thru 3rd. These gears are very quiet with no vibration issues. A good compromise for those who need a little more than 3.73s.

  Great gear ratio for blown ponies

  I installed these in my 94 GT that's been changed to a built 351 with a Paxton Novi 2000 blower and intercooler. Went from 11.03 second 126.4 mph 1/4 mile to 9.84 second 138,3 on a small tire daily driver. The price is the cheapest 1 second plus gain that I've ever invested in. Great ratio for the longer rpm range for blown motors. Thanks AM :)

  390

  Had gear professionally installed, greater acceleration and higher rpms, unfortunately the gear whines, would recommend ford racing, but they dont make a 390 so i chose motive because i wanted a 390, ill live w it

  Great get up and go.

  I feel that these are the great in between gears to have. I didn\'t want 3.73\\\'s but I didn\'t want 4.10\\\'s either. You will get a great improvement when you hit the throttle.

  better than 4.10s imo

  Went from stock to 4.10s. that lasted about a year. Decided to go down to 3.90s. They are definatly a much more street friendly gear, but still get up and move! 3rd redlines at about 85, and 4th is around 115, so you'll definatly still have plenty of oomph to blow past the slow traffic on the freeway-
