Front Ring and Pinion 5.38 Raptor 4x4 Suzuki Samurai (8x43)
A heavy-duty Raptor 4x4 5.38 ring and pinion for the Suzuki Samurai front axle: 8-tooth pinion, 43-tooth crown wheel. The shorter ratio gives back the torque lost to oversized tyres. Matches a driveshaft flange with 8 mm bolt holes.
Front Ring and Pinion 5.38 Raptor 4x4 Suzuki Samurai (8x43)
Fit bigger tyres to a Samurai and the car often loses its character: the engine revs, but the vehicle still will not pull up a climb without slipping the clutch. The reason is simple — the rolling circumference grew while the axle ratio stayed factory. A shorter ring and pinion gives back what the tyres took away.
This is a heavy-duty Raptor 4x4 5.38 gear set for the front axle of the Suzuki Samurai: an 8-tooth pinion running a 43-tooth crown wheel. For the car to drive properly, the matching rear set goes in at the same time.
Ratio 5.38 (8 x 43) | Axle Front | Driveshaft flange 8 mm bolt holes |
Key benefits
- The shorter 5.38 ratio restores torque at the wheels after a tyre upsize, so the car pulls away calmly and the clutch lives longer.
- Heavy-duty construction compared with the factory gear set, which matters on a tuned engine and in technical driving.
- An 8-tooth pinion and a 43-tooth crown wheel: verifiable numbers rather than a vague "low ratio" claim.
- The front set has a matching rear counterpart (RAP-06632A), so both axles can run identical gearing.

Who it is for. Samurais on oversized tyres where the factory ratio no longer suits the wheel size, and cars driven technically, where low-speed pulling power is what counts. It is also a sensible upgrade during an axle rebuild, when the differential is apart anyway.
Fitting notes
Swapping a ring and pinion is a job for someone who can set contact pattern and bearing preload — a badly shimmed differential howls and will not last a season. Two things to note. First, this set matches a driveshaft flange with 8 mm bolt holes. Second, the manufacturer sells the differential setup kits (bearings and shims) separately under their own code, so the gear set alone does not include them. And whenever you change axle ratio, both axles are changed together. Our workshop builds axles like this regularly if you would rather hand the setup over.
Why buy it
- It changes how the car drives on big tyres more than most upgrades at a similar price.
- Heavy-duty Raptor 4x4 gears instead of a used factory set of unknown history.
- The 8 x 43 tooth count is stated openly, so you know exactly what you are buying.

Frequently Asked Questions
What is the exact tooth count?
An 8-tooth pinion and a 43-tooth crown wheel, which gives the 5.38 ratio.
Do I have to change the rear ratio as well?
Yes. Both axles must run the same ratio. The rear version is RAP-06632A.
Are bearings and shims included?
No. This is the gear set only. The manufacturer offers differential setup kits for Suzuki under a separate code.
Will it fit any driveshaft?
This version is made for a driveshaft flange with 8 mm bolt holes, so check yours before ordering.
Can I fit this myself?
Changing a ring and pinion requires setting the contact pattern and bearing preload with the right tools. Without that experience it is better left to a workshop.
