toyota ring and pinion question

[tommy gun]

would a 4:88 be a stronger gear set than a 5:29?

 

[Not Jobless]

Typically, a numerically lower (not lower ratio) ratio gear set has a larger pinion gear which means more metal and more strength.

So the 4.88 should be stronger than the 5.29...but by how much?

:awesomework: the 4.88 is the stronger gear.

I was gonna say something smart ass but I will refrain

The exact answer: yes, 4.88 is stronger. By how much... the difference is probably negligible. I have heard people say to stay away from 5.71 toyota gears... but that's anecdotal at best... if you want 5.29's, run 'em, and don't worry about strength issues compared to 4.88's.

I have had both 4.88's and 5.29s. I am not a rock crawler guy but I gave my truck hell spinning 35's and I haven't broken the 5.29s. But yes the 4.99s are stronger.

 

[TB-F]

4.88's are stronger. Toy r&p's fail at the pinion 99.99999% of the time my experince dictates. A toy 5.29 pinion has 7 teeth. A toy 4.88 has 8 teeth. I'l tell you how they hold up after abusing a set of yukon 4.88's in my wife's 4.3L powred 4 runner soon :awesomework:

awsome info! do most of you with 4:88 and big tires (over 35's) have motor swaps?

If they are stock 4.88s they suck. I have broke three toy R&Ps and they have all been ring gear but they were two 4.38s and one 4.10

Proper set up will play a major part in there life span.
