Revolution Gear & Axle 87-97 Nissan Patrol GU/GQ & 97-17 Y60/Y61 H233B 5.13 Ratio Gear Package

This is a 5.13 ratio ring and pinion gear set from Revolution Gear & Axle, designed for the H233B differential found in 1987-1997 Nissan Patrol GU/GQ and 1997-2017 Nissan Patrol Y60/Y61 models. Changing your differential gear ratio is a common modification when you've altered your vehicle's tire size or are looking to improve performance for specific driving conditions, like towing or off-roading. A lower numerical ratio like 5.13 will bring your engine's RPMs back into a more efficient range with larger tires, improving acceleration and drivability.

Revolution Gear & Axle is known for producing well-built drivetrain components. This gear package includes the ring and pinion gears, which are precision-machined for a proper mesh and quiet operation. Installing a new gear set often involves replacing other wear items in the differential, so it's important to consider what else you might need for a complete rebuild. This kit is intended for those looking to significantly change their vehicle's gearing for enhanced performance.

When undertaking a differential gear change, it's crucial to have all the necessary installation components. While this package provides the core ring and pinion gears, you'll typically need a master bearing and seal kit, which includes bearings, races, seals, and shims, to properly set up the new gears. Ensure you consult the manufacturer's installation instructions or a qualified mechanic to confirm all required parts and procedures for a successful installation.
