This is a pair of front and rear crown wheel and pinion gear sets, designed to be fitted inside your vehicle's front and rear differential housings. These high-quality Japanese-made gears are the perfect solution for Patrol owners looking to optimise their vehicle's performance after modification.
Changing your differential gear ratio is essential when you fit larger diameter tyres to your 4WD. Larger tyres increase the overall gearing, which leads to a loss of acceleration, poor fuel economy, and increased strain on your engine and transmission. By installing a "shorter" ratio like these 4.625 gears, you restore the vehicle's mechanical advantage, bringing performance and efficiency back to, or even better than, factory levels. This is crucial for towing, off-road crawling, and everyday driveability.
If you fit larger tyres without correcting the gearing, your vehicle will feel sluggish and underpowered. The transmission will struggle to find the right gear, especially on hills, and you will place excessive stress on your clutch, torque converter, and other drivetrain components, potentially leading to expensive and premature failure.
Product Features
- Optimised 4.625:1 Ratio: The ideal ratio to correct your vehicle's gearing after fitting larger tyres (e.g., 35-inch). This restores lost acceleration and torque, improves fuel economy, and reduces strain on your engine and transmission.
- Complete Front & Rear Set: This is a complete kit containing both front and rear crown wheel and pinion sets, ensuring a perfectly matched driveline conversion.
- Japanese Precision & Strength: Precision-machined in Japan from high-grade materials for superior strength, quiet operation, and long-term durability. Avoids the gear whine and premature failure common with cheaper, inferior gear sets.
- Installation Requirements: Professional installation is required. This is a complex workshop job that requires specialised tools to set backlash and pinion depth correctly. A differential rebuild kit, which includes new bearings, seals, and shims, is highly recommended for installation. You will also need fresh differential gear oil.
