Axles

T-series Axles

From left to right: RA40, RA23, TA22

Lots of people talk about T-series diffs, kouki and zenki etc, but few people ever mention the axles. And then there's the people who say that if you have a non-LSD T-series diff and you want to put a TRD LSD center in, then you need to shorten the axles about 5mm...

Well anyways, what I wanted to point out is:

Not all T-series axles are created equal. There are at least (and probably more) 3 different sorts:

• TA22: These are fairly short, fairly thin, and use tiny bearings
• RA23/28, TA23: These are slightly longer than TA22, look to be a bit thicker, and use a much bigger bearing
• RA40/60: These are identical to RA23, except 30mm longer. Same bearing etc.

Measured with my dodgy tape measure, from axle flange to end:

• TA22: 550mm
• RA23: 555mm
• RA40: 585mm

I'm not sure about the mounting plate, but visually they look the same. Splines are the same (obviously).
