This Nissan H233B Front Ring and Pinion is a Revolution Gear 4.88 ratio set built for Nissan Safari and Patrol front 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.
In particular, this matches how the front differential turns relative to the ring gear. Since it ships with no carrier break, you should first confirm compatibility with your existing carrier before ordering. Overall, this matches the material and process Revolution Gear uses across its wider ring and pinion range.
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.
This set suits the Nissan H233B front 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. Pair this with our matching H233B rear 4.88 set if you’re doing both ends. If you’re unsure which housing your vehicle uses, a diff specialist can confirm it from the casting numbers before you buy.

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.
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.
Price was the price, no surprises. Return pickup was already booked which made life easy.
