Review on Upgrade Your GM 12-Bolt Truck Differential with 🔧 USA Standard Gear (ZG GM12T-342) Ring & Pinion Gear Set by Matt Welch

didn't fit my econoline 06. the hole pattern on the gear was smaller than the pattern on the carrier. I'm not sure if I received wrong parts or differences in holders. 8.8. The retainer is a Yukon Duragrip that has been tested to fit the factory sprocket. Someone returned this box with an 8.8irs 4:10 gear set for a Ford Mustang. Amazon took care of it and a replacement is on the way.
