The MFactory final drive gears are cut from high quality fully Carburised Forged Nickel-Chromoly Steel while also benefiting from our proprietary heat treatment process. As a result, we are proud to offer enthusiasts the best final drive gears on the market today.

By changing your final gear ratios, you can experience a dramatic increase in acceleration, giving you on average, a 10-15% increase in torque throughout the entire rev-range over the OEM Final Drive.

The 4.57 kit has been added to our transmission page on our website.

VERY tempting.

Does this gearset give any whine?.. I know some of the cheaper gears can.

 

I believe there is some whine. This can apparently be affected by changing the oil. Torco or amsoil are the upgrades. Opie would be the guys for that. I don't think cost comes into it, more the nature of the beast. I will stand corrected though. These kits are engineered for performance and strength.

I'll be going for these soon!

mmm....

Does anybody have stats on what improvement to acceleration etc this would give? Does a 15% mean 0-60 improvement by 15% as this would equate to about a second off the quotes figures.

I imagine that this also translates into more gear changes, lower top speed etc.

What are the real world benefits and disadvatages?
