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
