Description
Nissan H233B Rear Ring and Pinion (4.88 Ratio, Safari/Patrol)
This Nissan H233B Rear Ring and Pinion is a Revolution Gear 4.88 ratio set built for Nissan Safari and Patrol rear differentials. Specifically, Revolution Gear manufactures it from high-grade 8620 steel using precision gear cutting and heat treatment that meets or exceeds OE standards. As a result, it holds up to demanding towing and off-road use.
Specifications
- Gear Rotation: Standard
- Pinion Splines: 29
- Ring Gear Diameter: 9.5 inches
- Ring Gear Bolt Thread: 9 x 10mm
- Carrier Break: No Carrier Break
- Material: 8620 steel
- Country of Manufacture: Korea
In particular, this combination of steel grade and precision cutting keeps noise and wear low over the life of the gear set. Since it ships with no carrier break, you should first confirm compatibility with your existing carrier before ordering.
H233B Rear Ring and Pinion Performance
This 4.88 ratio improves torque delivery, towing performance, and off-road capability. Additionally, it keeps the driveline smooth and quiet. It suits Safari and Patrol owners running larger tyres or heavier loads who want more usable power at the wheels. For example, installers prefer this set for consistent setup and reliable results. Overall, it handles both daily driving and extreme conditions without drama, which is why workshops keep coming back to it for H233B rebuilds.
Fitment
This set suits the Nissan H233B rear differential specifically, found in Safari and Patrol models. However, always confirm your differential code before ordering, since Nissan used several housings across these model ranges. Also, front and rear ratios should match on most setups, so check your front diff ratio too. If you’re unsure which housing your vehicle uses, a diff specialist can confirm it from the casting numbers before you buy.

★★★★★ Quiet as new, swapped it over in an afternoon
Mark T · Timaru · Example review Had the classic whine at 80. Diff turned up next morning, swapped it over myself with the fitting guide, return label was in the box. Three weeks on and dead quiet. Core charge came back inside a week.
Reply from the Gearhead Diffs teamCheers Mark, glad the guide did the job. Thanks for getting the core back quick.
★★★★★ Good part, freight took an extra day
Hemi R · Gisborne · Example review Rural delivery so it was two days not one. The part itself is mint and the oil was in the box which I did not expect.
