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
