Dana 30 Front Axle Wrangler JK and JL 4.10-5.38 Ratio Ring and Pinion

Restore Factory Performance to Your Sport or Sahara.

For owners of Jeep Wrangler Sport and Sahara models, adding larger tires often exposes the limitations of the factory gear ratio. The result is a Jeep that feels underpowered on the highway and struggles to climb obstacles on the trail. Revolution Gear & Axle offers a premium solution to wake your engine back up without requiring a complete axle swap.

At Overland Truck Store, we trust Revolution Gear because they prioritize precision manufacturing. These gear sets are double-lapped to ensure a smooth, quiet contact pattern that rivals OEM quality. This attention to detail means you get a drivetrain that remains civilized on the pavement while gaining the mechanical advantage needed to turn 35-inch or 37-inch tires off-road.

Constructed from high-grade steel and heat-treated to endure the stresses of off-camber trails and steep ascents, these gears are the standard for reliability in the aftermarket. Whether you are regearing a JK or the newer JL platform, this is the foundational upgrade your build needs.

Features & Specs:

• Application: Jeep Wrangler JK (2007-2018) & JL (2018+) Front Dana 30 axles (Sport/Sahara/Willys).

• Smooth Operation: Double-lapped manufacturing process ensures quiet highway cruising and easy setup.

• Ratio Options: Available in 4.10 to 5.38 to optimize your RPMs for any tire size.

Installer Note: This gear set is designed for the Dana 30 front axle found in non-Rubicon models. It will not fit Rubicon models equipped with the Dana 44 front axle. We strongly recommend installing with a new Master Install Kit to ensure bearing longevity.
