Tired of waiting for your ring and pinions to break in before towing or hitting the trail? Trail-Gear has your solution! Our Trail-Creeper Super Finished 29-Spline Ring And Pinion Gears require absolutely no break-in time. You can install these gears and get right into the action without the need to worry about premature ring and pinion failure.

Trail-Creeper Super Finished 29-Spline Ring And Pinion Gears are made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance. The gear teeth are cut using Gleason CNC hobbing machines and 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.
Key Benefits:

• No break-in period
• Less friction
• Reduced wear allowing bearings and gears to last longer

Trail-Creeper Super Finished 29-Spline Ring And Pinion Gears are treated with REM® Isotropic Super Finishing (ISF) process. The process that is used to polish our gears is the same used for aerospace applications.

The REM ISF process removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 in Ra! This means that there is less friction between the gears, reducing wear by 95 percent and allowing the gears and bearings to run cooler and last longer.

The REM ISF process not only decreases friction and wear in the gears but also creates a non-directional surface that increases lubricant retention on the gear surface, reducing lubrication requirements.
