Aftermarket Ring and Pinion/Diff. Who do you buy and why

[ali_c20]

I run the clutch version. The true trac is not available for my 3.08 gears (12 bolt truck axle). I didn't want to swap gears because then I would have to change the front diff too. The carbon clutches are announced to last 100.000 miles and I don't tow or do hard offroading.
The clutch springs are adjustable so that you can customize the rear end.

Heard many great things about motive, kid I know runs a small little axle service, overhauling them or just selling takeouts, or total restorations. He sets up motive in axle overhauls. All he does until someone specifys differently

Richmond obviously is generally the top dog.

Yukon I've heard was Wong-****.
