Description
These are the new harder versions of the ST-R bevel gears. The new chrome moly steel material they are made from is stronger and lasts longer than the steel versions. Take care when installing Ring and Pinion Gears, they must be shimmed correctly. Make sure you run them with zero backlash for a few tanks, then check them. There should be close to zero backlash even after this. Check them regularly and re-shim if necessary. They should last for many gallons of fuel if done correctly.
