Raptor 4x4 Front Differential Gear Set 5.125 for Nissan Patrol Y60/Y61

Bigger tyres mean more traction and ground clearance, but also more torque load and noticeably worse driveability, since the engine has to spin heavier, larger wheels through the same factory axle ratio. The result is weaker acceleration, higher fuel consumption and a gearbox working harder than it should.

Raptor 4x4 offers a revised front differential gear set at a 5.125:1 ratio for the Nissan Patrol Y60 and Y61 – a standard fix used specifically to compensate for larger tyres and restore proper driveability.

What's in the kit

• 1x front axle ring gear, 41 teeth
• 1x front axle pinion gear, 8 teeth

Key benefits

• A 5.125:1 ratio (41/8 teeth) compensates for the effect bigger tyres have on driveability and real-world fuel use.
• A matched set for the front axle – the ring gear and pinion are supplied as a pair, so there's no risk of mismatched tooth counts.
• Fits both the Y60 and Y61 – one product covers both front axle generations.

Technical data

Who it's for: Y60/Y61 owners running noticeably larger tyres than stock who feel the drop in driveability and the rise in fuel consumption, and want to fix it by re-gearing the axle instead of living with a ratio matched to smaller wheels.

Installation / notes

Swapping the ring gear and pinion means working inside the differential and setting backlash and tooth contact precisely – a job for a workshop experienced with Nissan axles, not a quick driveway swap. The kit covers only the main gear set (ring gear + pinion) – bearings and seals are sourced separately based on the condition of your axle.

Why it's worth it

• One ratio covers both generations (Y60 and Y61) – less risk of ordering the wrong part.
• A factory-matched gear pair, instead of hunting for compatible replacements separately.

If your Patrol feels noticeably weaker off the line since you fitted bigger tyres, re-gearing the front axle to 5.125:1 is a proven way to get that driveability back.

Frequently Asked Questions

Does this set fit both the Y60 and Y61?

Yes, the same 5.125:1 gear set fits the front axle on both generations – Y60 and Y61.

What exactly does the kit include?

The front differential main gear set: ring gear (41 teeth) and pinion (8 teeth). Bearings and seals are not included.

Can I install this myself?

Fitting the gear set requires precisely setting backlash and tooth contact inside the differential – we recommend having it installed by a workshop experienced with Nissan Patrol axles.
