First Picture: On the left a Toyota 8" (T8) pinion with 27 splines. OEM correct for 2002 and older Toyota Tacoma, 4-Runner, Pick-Up, Hilux, Etc
In the Middle a Nitro Toyota 8" (TV6) pinion with 29 splines. OEM correct for 2003 & newer Toyota applications. With a Nitro YOKTOYFITKIT-29 you can now upgrade early Toyota models to the superior 29 spline pinion and Nitro will never make you downgrade a late model Toyota to a 27 spline pinion like our competitors!
For comparison on the right a Nitro Toyota 8.4" pinion. Close up of the pinion splines.
Bridged bearing caps in the Toyota 8.4" housing. Size difference between 8" and Land Cruiser 9.5"
