MM Differential Rebuilds
At Metric Mechanic we take differential building to another level and are proud to offer the finest rebuilds to both individuals and shops. There are plenty of reasons to choose the MM for your diff rebuild. Hopefully, this introduction to our numerous options will guide you towards understanding why we are the right choice for all of your differential needs.
What sets a Metric Mechanic differential apart from the rest? Is it the way we pay attention to detail? Is it our ability to offer you options that no one else can? Is it our ability to make the process quick and easy? We believe the answers to these questions are yes, and most importantly, so do our customers.
In general, we choose to not sell individual differential parts. There are a few exceptions, but we feel the process is faster, easier, and in the long run, much cheaper for both the customer and ourselves to have a professional make it right. We set the carrier breakaway torque to what it should be. We set the rolling torque, and most importantly we set gear backlash to insure you are getting the best differential available. Out stock includes shims for the pinions and the side flanges for almost every different style of differential. Our experience and access to the right tools and parts ensures that every differential we build is of the highest quality.
Also, we offer a wide range of options for your style whether you are a daily driver or racer looking for a little more time advantage. All differentials receive new seals and new bearings. We offer the ability to switch gear ratios easily because we keep many of them in stock. Our Variable Limited Slip, or VLS, allows for faster cornering, and better corner exiting acceleration. We offer a standard two clutch disc rebuild all the way up to a full five clutch disc race differential.
At Metric Mechanic our meticulous attention to detail, our inventory, and our countless years in the field means you get the best differential money can buy. Performance, reliability, and results are what “drive” us every day at Metric Mechanic.
