Q:

Can this except a 39 tooth Ring Gear from a 1964 Eaton Ho72 10Bolt Full Floater and is this for 3/4 ton application ?

Asked by WILLIAM T on November 20, 2018

A:

I am sorry but no it cannot. This carrier is not made to fit a HO72 and the only thing that I know you can do is if you have a open non-posi carrier you can put in a 225S-10 and get custom axles to fit the side gear axle splines.

Answer This Question

Q:

14 bolt 10.5 gm rear.
Changing to 5.38 thick ratio and need to know if this is the correct limited slip

Asked by GADDY MOUN on January 29, 2018

A:

Thank you for your question. The EATON 19689-010 differential carrier fits factory 4.11:1 and numerically lower ratio. If you have a thick gear designed to work with this carrier such as G2 Axle & Gear part number 2-20232-538X, it will work for your application. However, it is not compatible with gearsets designed for 4.56:1 and numerically higher carrier.

Answer This Question

Q:

Will this fully take care of my "one wheel wonder" on my chevy 3.73 rear end, as in lock down both before spinning?

Asked by BEN on December 17, 2017

A:

Thank you for your question. EATON 19689-010 is a limited slip differential, which would allow minimal slippage of the two opposite wheels. Please call for specific fitment and compatibility with your specific application.

What can I say? It's an Eaton Posi-traction unit. It is just as pictured which leaves me to believe it has conical clutches in it. Got me hooked up in my street rod truck. Functions like they have for the last 60 or so years.
