Revolution Gear & Axle 2018+ Jeep Wrangler JL Non-Rubicon Dana 35 Rear 4.56 Ratio Gear Package

This is the Revolution Gear & Axle 4.56 ratio gear package specifically for the 2018 and newer Jeep Wrangler JL models equipped with the Dana 35 rear axle and NOT the Rubicon package. Changing your differential gear ratio is a common upgrade for Jeep owners, especially when fitting larger tires. A 4.56 ratio is a popular choice for JLs running 35-inch to 37-inch tires, as it helps bring your engine's RPMs back into a more efficient and responsive range on the highway. This package aims to restore or improve your Jeep's on-road performance after modifications.

Revolution Gear & Axle is known for providing well-built drivetrain components. This package includes the essential gears and installation hardware needed to re-gear your rear differential. You'll find the ring and pinion gears, which are the heart of the ratio change, along with bearings, seals, and shims required for a proper installation. Using a complete installation kit like this ensures you have all the necessary small parts to do the job right the first time, avoiding potential issues down the road. Proper installation is critical for the longevity of your differential, so it's recommended to follow the manufacturer's detailed instructions or consult a professional mechanic.

When installing a new gear set, it's important to follow the break-in procedure recommended by Revolution Gear & Axle. This typically involves a period of moderate driving with specific temperature and mileage limitations, followed by an oil change. This process allows the new gear teeth to properly mate and wear in, ensuring optimal performance and durability. This kit is designed for the Dana 35 rear axle found in non-Rubicon JL Wranglers; ensure your vehicle has this specific axle before purchasing.
