Overview

Longfield Super Finish Ring and Pinion Gears

Longfield's Super Finish ring and pinion gears offer major benefits like zero break-in time, allowing immediate trail use, thanks to their advanced REM Isotropic Super Finishing (ISF) process. This process creates a mirror-smooth surface, drastically cutting friction, heat, and wear for improved performance, durability, and quieter operation, all while using strong 8620 chromoly steel and precision CNC machining. These are the very same type of components that have won multiple championships in professional desert racing and competitive rock crawling circuits and have proven themselves on some of the most grueling off-road courses in the world. Longfield ring and pinion gears are sold as a set. They are also available in kits that often come with high-quality Koyo bearings, new bolts, seals, shims, and essential solid pinion spacers (preventing loosening), and the necessary hardware for a comprehensive upgrade.

Key benefits and features:

* Superior strength—made from heat-treated 8620 chromoly tool steel with a 5-cut tooth profile for better load distribution
* Quieter operation—high-precision Gleason CNC machining results in a more accurate, quieter-running gear set, ideal for daily drivers
* No 'break-in' required—the ISF process eliminates the need for the typical break-in period, letting you hit the trails immediately after installation
* Reduced friction and heat—the super-smooth, low-micro-roughness surface minimizes friction, leading to less heat buildup and improved efficiency
* Enhanced durability and life—less friction means less wear, increasing the overall lifespan of the gears
* Better torque transfer—the combination of accuracy and finish allows for more efficient torque transmission
* Improved oil retention—the super-finished surface holds oil better, aiding lubrication
* Enhanced performance—helps restore power and acceleration lost with larger tires, allowing the engine to operate in a more efficient RPM range
* Better value—Longfield goes directly to Tier 1 OEM manufacturers to have gears made to their exact specifications—by cutting out the middlemen, they can offer the highest quality gears at a competitive price
