Speedometer Gears for Jeeps
Changing speedometer gears is quick and easy. But why this change is needed? Well, when someone add larger tires or ring & pinion gears on a vehicle, speedometer will give you an inaccurate reading. Simplest way to correct this problem is to replace the Speedometer Gear. This simple procedure takes only a few minutes to complete. Charts are commonly available which list the most common tire sizes and ring & pinion ratios.
Just pick the correct chart (cable or electric speedometer), pick your Jeep Tire
size, and ring and pinion ratio to find the right speedometer gear.
A precise odometer reading is important both on and off road when traveling by mileage increments and for safety on the highway. e.g. When an
off road map specifies that 0.5 miles from point X you need to make a left, you want to be sure you have driven 0.5 miles before you make that left.
Factory speedometer variances are +/- 3-5% with the manufacturer tending to err on the slower side to be safe. Our recommendations for speedometer
gears are based on the manufacturer’s published tire specs. As you can imagine, this may vary from manufacturer to manufacturer.
