Scott's Patrol Progress

[tigweld]

TrueHi9 says that the higher the ratio (for a high pinion), the stronger the gear set. They have a pretty big section on their website explaining why the reverse cut gears are stonger in the higher ratios rather than weaker.

I don't know if that applies the the Toyota stuff also, but from the theory they use, it should.

i don't see them saying that at all, he only compares the it similar ratio dana 60 parts. all i gather from that (as i have read it before) is that due to high hypoid design of the 9" and large and low pinion offset you can get a better tooth pitch and cross section compared to a normal design. this doesnt apply to toyota as there pinion offset is not as extreme as a 9".

Cross sectional area X overlap

representative of overall strength)
Hi9 ratio 4.11 4.57 4.86 5.14 5.38

yes but that is due to the high hypoid, only on a 9" will it be that high. when I made the first post I was thinkin in relation to decent front axle strength as the 5.29 toyota gear set can't be nearly as strong as 4.88 toyota set up.

I got it now... I need to do a little more research on the Toyota HP I think

That was my first impresion but I didnt read in detail so I didn't post up. Any of the Hi9" R&P's will prob be ok (def with the 4 cyl? - I hesitate to say def with you ), but you could gain strength with a higher toy gearset that could potentially make a more real world diff - IE there is a chance you break a 5.29 when you would not have broken a 4.88 etc.

scott said to post these for him.

1350 U-joint?

i think thats what he said.

use the ruler on the wall to measure it.
