Losi new LOSB3535 Ti-Nitride Ring and Pinion gear set are exact replacements for the hardened steel gears used in the LST and LST2. These new gears are made to the same exacting specifications and tolerances from premium steel alloy and hardened for increased strength like the gears used in the LST/2. They then get an additional hi-tech Titanium–Nitride process that creates a super hard shell that also has a much higher lubricity. This means the gears mesh smoother for less resistance as well as longer wear. The Titanium-Nitride process is like that used on Formula One racecars and the space shuttle so you know it’s got to be good.
