If you're looking to change your Nissan Patrol's differential gear ratio, this 4.88 ratio gear package from Revolution Gear & Axle is a solid option. This package is designed for the H233B differential found in 1987-1997 Nissan Patrol GU/GQ models and 1997-2017 Nissan Patrol Y60/Y61 models. Changing your gear ratio is a common modification when you've upgraded to larger tires, as it helps bring your engine's RPMs back into an optimal range for driving, improving performance and fuel economy.

Revolution Gear & Axle is known for making well-built drivetrain components. This package includes all the necessary gears and bearings to perform a complete ring and pinion installation. You'll find a new ring gear and pinion gear, along with a full set of installation bearings, races, and seals. This comprehensive kit means you won't have to hunt for individual pieces, making the installation process smoother. The 4.88 ratio is a popular choice for Patrol owners who have installed 35-inch or larger tires, as it provides a good balance between on-road drivability and off-road capability.

When installing a new gear set, it's crucial to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving with no hard acceleration or heavy loads, followed by an oil change. This process allows the new gear teeth to properly mate and wear in, ensuring long-term durability and quiet operation. Always refer to the Revolution Gear & Axle installation instructions for the specific break-in procedure and any special tool requirements.
