In 1984 he moved his garage business into a commercial building and in 1986 he began parts distribution. In 1989 Randy returned to his home state of Washington and opened a small service shop in Redmond, WA. Five years later, he relocated the shop north to Everett, WA and in 1996, with a growing customer base and the vision of becoming the number one source for the nation's differential needs, Randy changed the company name to Randy's Ring & Pinion. With typical forward-thinking vision, Randy recognized this area as a future hotbed industrial district, with expansion opportunities focusing on parts manufacturing and distribution. By 2001, sales boomed such that a new location across the continent was needed, and this vision became a reality with the opening of the Tennessee warehouse. Our bi-coastal locations enable us to ship our products quickly to customers around the nation. In 2002, Randy's expanded into a new 58,000 square foot office and warehouse space in Everett, WA. In 2005, we opened a third warehouse in Fresno, CA. Review: First set was good. Bought a second set and the bearing surface was rough and unfinished and out of spec. 50/50 chance on good or bad Review: Perfect fit after 2 MOTIVE GEAR JUNK sets did not fit correct. Will NEVER purchase motive gear again. ## Features - 1 Year Warranty - Made from 8620 Steel - Precision Machined for Individual Differential Applications - 29 Spline - 12 Ring Gear Bolts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0078U9NFS | | Assembly Required | No | | Brand | USA Standard Gear | | Customer Reviews | 4.0 4.0 out of 5 stars (3) | | Date First Available | 22 June 2013 | | Item Dimensions LxWxH | 40.6 x 30.5 x 15.2 Centimeters | | Item Weight | 8 kg 620 g | | Item model number | ZG D70-373 | | Manufacturer | USA Standard Gear | | Manufacturer Part Number | ZG D70-373 | | OEM Part Number | ZG D70-373 | | Product Dimensions | 40.64 x 30.48 x 15.24 cm; 8.62 kg | | Volume | 1596 Cubic Inches | ## Images ![USA Standard Gear (ZG D70-373) Replacement Ring and Pinion Gear Set for Dana 70 Differential - Image 1](https://m.media-amazon.com/images/I/71+DwZRv9kL.jpg) ## Customer Reviews ### ⭐⭐⭐ Review *by N***E on 23 September 2019* First set was good.
