Trail-Gear is proud to offer Longfield Ring \u0026amp; Pinion Gears.

The 5-cut process results in teeth with a tapered tooth profile. This increases contact area and spreads the contact load along a wider area, resulting in less stress on the ring gear teeth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBetter Machining:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe gear teeth are cut using Gleason CNC hobbing machines \u0026amp; cutters. Gleason gear-cutting technology produces an unprecedented level of accuracy and surface finish, which allows the gears to transmit more torque and improve fuel efficiency. The higher accuracy and surface finish also produces a quieter-running gear set, which means they will work great on the daily driver too.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBetter Finish:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAll Standard Finish ring gears are black phosphate coated for wear resistance \u0026amp; corrosion protection. The black phosphate coating provides a microporous layer on the surface to hold lubricants to minimize friction between gear teeth. This results in less wear during the initial break-in period and increases the overall life of the gears.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBetter Value:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWe go directly to Tier 1 OEM manufacturers to have gears made to our exact specifications.
