So im getting ready to put an aftermarket Diff in my car and I figured i might as well do gears while im at it. I found a cheap solution of going to the 3.7 gears from another model. My only problem is that the gearset I found is from an "05-13 frontier" and the fit the c200k diff, but the seller is telling me that they are "Inclined gears" I wasnt aware that there were inclined/non inclined gears in our diffs. But my question is will these "Inclined Gears" work in an 03 MT/OEM VLSD housing with an Aftermarket diff?

Im pretty sure all the pinion gears are inclined to some degree. As long as youre sure it fits the housing youre using itll work, but you need to be sure.

Just be careful with the housings as they can differ even with the same code eg the R200 has several variants.

yeah, its a gamble cause theyre on ebay.. i might as well just get some 3.9's that i know are going to work. Thanks

If the original gears are straight cut and you replace with inclined (aka helical) you'll risk damaging the bearings or housing. Straight cut gears do not produce thrust loading on the gear shaft. Helical gears do, and depending on how inclined, the thrust load can be quite high.


It's possible that the Frontier uses taper roller bearings in the diff to handle the thrust load, whereas if the Z uses straight cut it would use normal ball bearings.

Heres the gears im looking at, it says theyre compatable with 370z, and g35/37 so i dont see how they could possibly be different. Anyone wanna take a look and give me an opinion?

Ebay truck parts on your Z, not so much.

..... use your head please and please refrain comment unless you have an educated answer and explination of such. Obviously I am not going to be using the differential, only the gearset, they're nissan gears not some ebay brand.

Do it right the first time. Why cut corners?

Not really cutting corners, just want a 3.7 gearset to go along with my carbotech and im not going to buy a brand new set if I can get one out of a used 370/g37 for a hell of a lot cheaper. Not skimping on quality, just trying not to be dumb with my money. Again please refrain from comment unless you have something to say pertaining to the subject at hand.
