Longfield ring and pinion gears are the very same 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. They offer superior strength, quiet operation, and durability through high-grade 8620 chromoly steel, precision 5-cut tooth profiling (increasing contact area), and Gleason CNC machining for high accuracy, smoother surfaces, and quieter operation, making them great for daily drivers. All 'standard finish' ring gears are black phosphate coated for wear resistance and corrosion protection. The black phosphate coating provides a microporous layer on the surface to hold lubricants to minimize friction between gear teeth, resulting in less wear during the initial break-in period and increases the overall life expectancy of the gears. Select the gears for your application. Key features and benefits: * Strength and durability—made from tough 8620 chromoly steel with a 5-cut tooth profile that distributes load better than standard gears, reducing stress and wear * Advanced tooth design utilizes a 5-cut process (instead of 2-cut) for a tapered tooth profile, increasing contact area and spreading load for less stress * Precision-cut using Gleason CNC machines for high accuracy, smoother surfaces, and quieter operation, making them great for daily drivers * Standard gears have a black phosphate coating to hold lubricant, reducing initial break-in wear and increasing longevity * Reduced wear and friction—features like black phosphate coating (standard) and REM ISF Super Finish (optional) minimize friction, especially during initial break in, extending gear and bearing life * Improved 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

Longfield inner hub gears will keep your rig running problem-free. When you run bigger tires, you put more strain and wear on your axles and hubs, creating more failure points. Made entirely from 4340 chromoly, these gears are so strong they'll handle all the abuse you put them through. Longfield inner hub gears are direct replacements that require no modifications. They offer locking gears for solid axles with the IFS-style, allowing you to use IFS locking hubs on your solid axles. Select the model designed for your vehicle application.

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
