Thinking about changing tire size we can help, consult our Look up chart for determination of engine RPM, gear ratio and tire size combination. Larger tires on lifted truck suffer from loss of power, changing the ring gear and pinion to a lower ratio is the answer.

Positraction units
We offer the following positraction units:
ARB Air Lockers
Auburn Limited Slip Differentials
Powertrax's LockRight, Performance Lockers and the new "no-Slip" Lockers
Posi-traction differentials ensure maximum traction under adverse conditions, they are designed to keep both wheels in a constant drive mode, with the ability to automatically "unlock" to permit necessary wheel speed differentiation. It also eliminates individual wheel spin for better traction and less tire wear.
| To determine your existing gear ratio: Place transmission in neutral and elevate one tire. Mark tire and driveshaft, turn tire two complete revolutions while counting number of turns of the driveshaft. This is your Actual Gear Ratio. i.e. 3 turns + 3.00 ratio, 4.1 turns = 4.1 ratio, etc. |
Example Existing gear ratio and tire size (Dia. in.) 307 ratio and 30 in. tall tires = 2060 engine RPM @ 60 MPH |
| Other Formulas that might be useful! Ratio = (rpm x tire diameter) divided by (mph x 336) RPM = (mph x gear ratio x 336) divided by (tire diameter) |
MPH = (rpm x tire diameter) divided by (gear ratio x 336) Tire Diameter = (mph x gear ratio x 336) divided by (rpm) |
