  Motion 4:10 Gears

  These gears are quiet and smooth and make your car feel like someone hid a big block under your hood!

  whine

  go with ford racings gear(At least thats what my shop told me). These gears whine. It annoys me, if it doesnt annoy you then buy them. The 4.10 and the tune made the car so stupid fast. Just got my first ticket in them!!!! LOL. That\'s why i give the 4.10\'s a five star! Definitly needs to be first mod

  Plan First...

  These 4.10 gears from Motive were the third modification I had done to my GT. The difference in acceleration was very noticeable. One thing everyone warned me about was a drop in fuel efficiency, which I did not see. The gears allow the engine to operate at a more efficient speed, which won\'t really affect mileage if you keep your foot out of it. Another common misconception is a drop in \"top speed.\" That is totally false. Your top achievable speed will actually increase now that the engine will be operating at a slightly higher rpm. Sure, the top redline speed is lowered to 156, but unless you can run 8\'s in the 1/4 mile, you have nothing to worry about. These gears did have a little bit of whine, mostly heard when no load was placed on them (coasting). Unless you hear excessive whine (almost like a loud hum heard at all times), you have nothing to worry about. I recommend you give these gears a couple of heat/cool cycles before putting the pedal to the floor. That hardens them up. Lastly, plan things out before you get 4.10s. For an N/A Mustang, they provide a good increase in acceleration at the cost of 500 rpms. If you plan on supercharging your Mustang, I urge you to consider 3.73s. Overall these are a very good set of gears, and ideal for most Mustang owners. I recommend purchasing the differential bearing kit with these gears.

  Wow!

  Hands down one of the best mods you can do on a Non-PI mustang. All I can compair it to is, it feels like the car has a shot of nitrous. Once again AM.com has the best/fastest shipping times around!
