PRODUCTS DESCRIPTION
GEAR RATIO GUIDE FOR LARGER TIRES
POISON FROG’s ring and pinions are engineered and manufactured to handle the increased loads of today’s performance vehicles. They are forged from a specific steel,lay a solid foundation, and then made by Oerlikon for precision machining in accordance with OE specifications.Because Oerlikon adopts the end face rolling method for processing, it has better applicability and impact load resistance, and can better meet there quirements of automotive drive axles for high speed, high speed ratio, low noise and high stability. In addition, compared with other gears, the Oerlikon gear of the same model can increase the bending strength of the special-shaped pinion by more than 10%, the bending strength of the large wheel by more than 14%, and the contact fatigue life by 30%, which greatly improves the service life of the gear.These tight tolerances ensure that they will be easy to set up and keep the noise level at OE specs.Next, the gears are heat treated for added durability to endure the harsh environments of a daily-driven vehicle. Finally, they are lapped to give the mating surface a smooth finish to reduce friction that can lead to noise and excessive wear.

Whenever you change tire size from the original size or from one size to another, this will have a direct effect on power and drivability. The chart below will help you to select the optimum gear ratio to bring the power and torque back to where you want them. Using the chart, first determine what your original gear ratio and tire size are, then follow the lines to find your approximate RPM at 65 MPH. Next find the new tire size on the left of the chart and look across to find the RPM closest to your original, the ratio listed at the top of that column will be your first choice for ratio. If you are interested in a change that will give more power or better mileage use the shaded coding as a guide.
