Product Description

The Revolution Gear & Axle D44RS-513RUB 5.13 Ratio Ring & Pinion set is a front-axle specific upgrade for the 2007-2018 Jeep Wrangler JK Rubicon models equipped with the factory front Dana 44 reverse-rotation axle. This ratio is ideal when you've installed oversized tyres, increased suspension height, or demand stronger front-end performance for off-road or heavy-duty use. The premium alloy steel construction and precision machining ensure long-term durability and quiet operation even in extreme use.

Installation involves removal of the front differential carrier, proper setup of backlash, gear pattern and preload. This kit is designed exclusively for the front Dana 44 reverse-rotation axle of the JK Rubicon - fitment beyond 2018 is unconfirmed, so verify your vehicle's front axle, rotation, and gear ratio before purchasing.
