Revolution Gear & Axle Jeep Wrangler JK/JL Dana 30 Reverse Front Axle 4.56 Ratio Ring & Pinion Set

This is the Revolution Gear & Axle Dana 30 reverse front axle ring and pinion set with a 4.56 ratio, designed for Jeep Wrangler JK and JL models. Changing your gear ratio is essential when you upgrade to larger tires, helping your engine and transmission work together more efficiently and restoring proper speedometer readings.

This set is built with strong materials for reliable performance. The 4.56 ratio is a popular choice for JK and JL owners running 35-inch to 37-inch tires, offering a good balance between on-road drivability and off-road capability. Proper installation is key to ensuring longevity and smooth operation of your drivetrain.

When installing a new ring and pinion set, it's important to follow the manufacturer's break-in procedure to properly seat the gears. This typically involves a period of moderate driving without hard acceleration or heavy loads.
