Rear Gear Polish & Coat Upgrade

We've known for years that a MicroBlue® bearing upgrade improves rear-gear throughput efficiency by 25%, but did you know that adding the ring and pinion to that equation adds another 25% increase in efficiency? And that because there's no break-in or "loosening" of MicroBlue bearings you can reduce bearing pre-load's by 50% or more? 

Here's how it works. Simply send us your ring and pinion gears (bearings removed), and we will REM® finish and MicroBlue® coat them and ship them back to you in 2 to 3 days. NOTE: Shipping is NOT included. For the complete package, simply add the bearing upgrade kit and you'll have the freest rolling, longest lasting and most efficient differential on the planet!
