Rough Country Dana 30 Front Axle Ring and Pinion Gear Kit; 4.88 Gear Ratio (07-18 Jeep Wrangler JK, Excluding Rubicon)Find parts that fit my vehicle

Optimized Off-Road Capabilities. Installing larger tires on your Jeep is great for improving ground clearance as well as getting that aggressive stance, but you can end up compromising your drivetrain’s performance. The Rough Country Dana 30 Front 4.88 Gears Ring and Pinion Kit changes all this by optimizing your engine and drivetrain setup via its higher gear ratio. This optimization results in greater off-road capabilities for your ’07 to ’18 Wrangler such as when rock crawling.

Re-Gearing Your Jeep’s Performance. The biggest benefit of re-gearing is this you’re able to regain some of the power and torque that’s lost from switching over to larger tires. Larger tires throw your stock gear ratio out of kilter, resulting in a slower-turning driveshaft. This less than optimal driveshaft performance results in the aforementioned loss of power and torque, as well as decreased fuel efficiency. Upgrading to a higher gear ratio brings back drivetrain performance to stock levels.

Tough Construction. The Rough Country Dana 30 Front 4.88 Gears Ring and Pinion Kit are forged from 8620 steel and heat-treated. This results in a ring gear and pinion set that’s extremely strong. In addition, the gears of this ring and pinion set are smooth-finished so that they run cooler and quieter than other ring and pinion gears.

Installation By a Professional is Recommended. The Rough Country Dana 30 Front 4.88 Gears Ring and Pinion Kit will require a number of specialized tools for proper installation, like a bearing press, a bearing puller, a dial indicator, and precision calipers. You’ll also need to have exceptional mechanical knowledge and skills, as well as several hours to spare. Consequently, an installation by a professional is highly recommended.
