Revolution Gear & Axle Jeep Wrangler JK/JL Dana 30 Reverse Front Axle 4.88 Ratio Ring & Pinion Set

This Revolution Gear & Axle Dana 30 Reverse Front Axle Ring & Pinion set features a 4.88 gear ratio, specifically designed for Jeep Wrangler JK and JL models. Swapping to a lower ratio like 4.88 is a common upgrade when you've increased your tire size, helping your engine and transmission work more efficiently to maintain power and drivability, especially off-road or when towing. This set is built for the Dana 30 reverse cut front axle, which is standard on many Jeep Wranglers.

The ring and pinion gears are made from durable, well-built steel, ensuring they can handle the increased stress from larger tires and off-road use. Proper installation is key for any gear change, and this set is designed to fit right into your existing Dana 30 housing. When you change your gear ratio, you'll also need to recalibrate your speedometer to ensure accurate readings for speed and mileage.
