Revolution Gear & Axle 96-04 Jeep Wrangler TJ/Grand Cherokee Dana 35 Rear 4.88 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to install a new 4.88 ratio gear set into the Dana 35 rear axle found in 1996-2004 Jeep Wrangler TJ and Grand Cherokee models. Changing your gear ratio is a significant modification that can dramatically alter your vehicle's performance, especially if you've upgraded to larger tires. A lower ratio like 4.88 helps bring your engine's RPMs back into an optimal range at cruising speeds, improving acceleration and making your Jeep feel more responsive. This kit is designed for those looking to optimize their drivetrain for off-road use or for handling larger tire sizes.

Inside this kit, you'll find a well-built 4.88 ratio ring and pinion gear set, along with all the necessary installation components. This includes Timken bearings, which are known for their durability and smooth operation, ensuring your new gears mesh correctly and last for a long time. You also get a complete installation kit with seals, gaskets, and hardware, so you have the essential pieces for a proper rebuild. Revolution Gear & Axle focuses on providing reliable drivetrain components, and this package aims to give you a solid foundation for a successful gear swap. Proper installation is key with gear sets; it requires careful setup and measurement to ensure the gears mesh correctly and achieve the right pattern for longevity and quiet operation.

When undertaking a gear ratio change, it's important to remember that you'll need to break in the new gears according to the manufacturer's instructions. This typically involves a period of moderate driving without hard acceleration or heavy loads, followed by an oil change. If you're installing these gears to compensate for larger tires, consider that this change will affect your speedometer calibration and potentially your anti-lock braking system (ABS) performance. You may need to address these systems separately to ensure accurate readings and proper function.
