Frequently asked questions
The best gear ratio depends on several factors, including the type of driving you plan to do (highway, off-road, climbing, etc.), the weight of your vehicle (including any added accessories or cargo), and your vehicle's specifications (engine, transmission, and tire size). For 37-inch tires on a Jeep JK, the recommended gear ratios typically range from 4.56 to 5.13. The most commonly suggested ratios are 4.88 and 5.13, with 4.88 being suitable for a balance of highway and off-road use, and 5.13 providing more power for off-road and climbing but resulting in higher RPMs on the highway.
The stock 3.21 gear ratio is often considered too sluggish for 37-inch tires. A common recommendation is to upgrade to at least 4.56 or 4.88, depending on your intended use. If you don't do much climbing and are mainly concerned with highway driving, 4.56 may be sufficient. However, if you plan to use your Jeep for more rigorous off-road activities, consider upgrading to 4.88 or even 5.13 for improved performance.
Upgrading from the stock 4.10 gear ratio to 4.88 or 5.38 gears will provide more power and torque for your Jeep JK with 37-inch tires. The choice between 4.88 and 5.38 depends on your specific needs. If you plan to use your Jeep primarily for daily driving and light off-roading, 4.88 gears should provide a good balance of performance and fuel economy. However, if you intend to do serious off-roading, tow heavy loads, or drive at higher elevations, consider opting for 5.38 gears for increased horsepower and torque.
For a manual Jeep JK Rubicon with 37-inch tires, the recommended gear ratio to maintain factory RPM and speed is typically 4.88. This ratio will provide a good balance of on-road and off-road performance while keeping RPMs relatively close to stock levels. However, if you plan to do a lot of off-roading, rock crawling, or climbing, you may consider going with a slightly lower ratio like 5.13, which will provide even more torque and power but result in higher RPMs on the highway.
When upgrading the gears on your Jeep JK with 37-inch tires, consider the type of driving you plan to do and your vehicle's specifications. If you primarily use your Jeep for daily driving and light off-roading, a gear ratio between 4.56 and 4.88 should provide a good balance of performance and fuel economy. However, if you intend to do serious off-roading, climb steep grades, or tow heavy loads, consider opting for a lower ratio like 5.13 or even 5.38, which will provide increased torque and horsepower at the expense of higher RPMs on the highway. Additionally, keep in mind that proper gearing can reduce stress on your vehicle's components and improve fuel economy by reducing the need for downshifting or "hunting" between gears.
