Nitro gears are machined....not stamped like most other gears, with Less than half the weight of standard gears. i.e. 69 tooth gear standard=7.5oz ~ 69 tooth Nitro gear =3.3 oz
The Nitro gear can not be put together backwards due to its notch design. Most Gears have only a small mark which is nearly unnoticeable in pic. Both halves are marked with the teeth count on it, not just on one.
Nitro gear is narrower. With the gear being narrower, the chain has a tendency not to ride up on the teeth as bad...creating less wear, allowing for less drag.Teeth are Teflon impregnated with our own special formula. Both the Teflon coating and the narrower gear, provide less friciton for less drag...which equals better performance.
It is made out of a better grade of aluminum than about 80% of the gears out there and is made to fit all standard four and six bolt drive hubs.
