Thinking about a Gear Vendors OD. Can Anybody Give Some Guidance?

I have had one behind the Passon aluminum 833 / street Hemi in my Duster for over a decade. After initially driving around doing the split-shift thing, that got shelved and now is only used on the expressway where I am going over 60MPH.

Small mod (cutting ,no BFH) to the trans tunnel to keep my driveline angle at 1.5 degrees down towards the differential.

It is pretty simple, drive it like your standard Mopar 4-speed until you go over 60, engage the OD and drop the revs. I have a 30" tall tire with a 4:30 gear. 65 MPH is around 2400 RPM....the sweet spot.

I like the A855 5-speed, but for me, it does not carry the time tested reputation of the 833.

I would do it again.
