Your Full Service Differential Repair Shop since 1982!


About Ring & Pinion Service

Ring and Pinion Service History

Ring & Pinion Service is the Sacramento area’s best and most experienced full-service differential repair shop. We specialize in differential repair and modification (that’s all we do!) so we’re very good at it. Originally established in 1982, our shop was previously located on Coloma Road in Rancho Cordova. We moved to our current location in Rancho Cordova in 2001. We designed our shop to our own specifications with 3 standard lifts and a 4 post motor home lift. Ring and Pinion Service obtains differential parts from our sister company West Coast Differentials. Therefore we have a huge inventory of parts available in the same building. Our team of expert technicians has a tremendous amount of experience in all aspects of differential repair. Ring & Pinion Service provides quality differential parts and repair that are guaranteed to run quietly and last a long time.

Ring and Pinion Service Employee Profiles

Erik Jorgensen, Technician:

Erik has been building differentials for Ring & Pinion Service since 1994. We’ve done the math and by very reasonable estimates he probably installs, repairs or customizes over 1,000 differentials a year. As of 2011, that means he’s easily worked on over 15,000 differentials. Erik truly is a differential repair expert. You won’t find a better technician to work on your differential.

Mike Miller, Service Manager:

Mike has worked at Ring & Pinion Service since June 2013. Since graduating from Wyoming Technical Institute in 1997, he has had 17 years of automotive experience, specializing in drive train. Mike comes to us from another local shop where he had worked for more than 15 years, the last 5 as service manager. He has a thorough knowledge of all aspects of differential repair and modification. Mike takes care of all communication with the customer throughout their Ring & Pinion Service experience.

Free Diagnosis & Estimates

At Ring & Pinion Service, we always offer free diagnosis and Free Repair Estimates. Most commonly, one of our differential experts will road test your vehicle (if possible) and give you an accurate diagnosis based on the symptoms and sounds that are present. We can then make recommendations for repair or upgrade of your differential, and provide you with an accurate repair estimate.
