Another Option - 5.37 R&P gears for 2015 Jimny AT

After being a member of this forum for almost 3 years, I finally took
the plunge and bought a 2015 Jimny A/T. I am stocking parts for an
eventual transformation of my Jimny. By 2016 I would like my Jimny
to be fully transformed with ARB locker for the rear, 31" tires,
regeared differentials, lifted or chop fenders to accomodate
the tires and a 8000 lb. winch in a winch bumper.

Today I bought a pair (front and rear) of Jimny 3rd member with
5.37 final drive ratio from a reputable Suzuki surplus dealer
here in the Philippines. I will pick it up tomorrow, today being a
Sunday. The 5.37 will give me a gear reduction of 1.31 from the stock
final drive ratio of 4.09.

My question is, I never knew that there are aftermarket differentials
available for a Jimny. . I wonder where these R&P gears came from?

I have attached a jpeg picture of the 3rd member that I will buy tomorrow.
The surplus dealer insisted that it is compatible for the new Jimny with smaller
3rd member for the front vs. the rear and I have no reason to doubt him as
he definitely knows his stuff.

Autos do have a different tatio to manuals .....not sure if this was the question

sorry for the confusing post Reaper. What i meant was,
How come I never read about after-market 5.37 (43:
Ring & Pinion gears available for the Jimny before?

5.37 is the genuine r&p from Jimnys with K6A engine (656 cmc), available in JDM.

ah okay. thank you minitecus, I thought they were aftermarket ring gears. So they came from stock suzuki jimnys' with a 660cc turbo engine from Japan? Thank you for the information.

That's very useful to know!
