We've spent the last year investing in tooling and staff to move all our hoop production in house. We have never been more confident in the fit, function and finish of our Driveshaft Hoop product line.
DHD's competition drive shaft hoops and blow shields are designed to keep you safe and minimize component damage in the event of a failure. This hoop is the newest addition to our product line and is designed to fill a large gap in fitment. The 600-407 is designed to work specifically with the AAM 11.5" rear axle in your 2011+ 2500HD 3500HD GM truck and some late model Dodge applications.

This hoop attaches to steel webbing that surrounds the circumference of the differential housing. Your housing must look like the picture below. (See Picture) Its designed to work on housings that do not have the thick webbing running forward to the pinion. Trucks that have the pinion support webbing require hoop 600-414 or 600-412.
