Revolution Gear & Axle 07-18 Jeep Wrangler JK Non-Rubicon Koyo Bearing 5.13 Ratio Gear Package

When you're looking to change your Jeep Wrangler JK's gear ratio, this package from Revolution Gear & Axle gives you the core components you need to get the job done. Inside this kit, you'll find a complete set of 5.13 ratio ring and pinion gears, along with a full installation kit featuring Koyo bearings. This specific ratio is a popular choice for JK owners who have upgraded to larger tires, typically 35 inches or more, helping to bring your engine's RPMs back into a more efficient range on the highway and improving acceleration off-road.

Revolution Gear & Axle sources quality components for their packages. The ring and pinion gears are precision-cut to ensure proper meshing and quiet operation. The included Koyo bearings are well-known in the drivetrain industry for their durability and smooth performance, which is critical for the longevity of your differential. This kit is designed for the non-Rubicon JK models, meaning it's intended for the smaller Dana 30 front differential and Dana 44 rear differential found in those Jeeps. Proper installation is key to achieving the benefits of a gear change, and this package aims to provide the essential parts for a successful rebuild.

Changing your gear ratio is a significant modification that affects how your Jeep performs both on and off the pavement. It's important to ensure you have the right tools and knowledge for installation, or to have a qualified mechanic perform the work. This package focuses on the gears and bearings, so you'll want to confirm you have other necessary consumables like gear marking compound, RTV sealant, and differential fluid before you begin.
