We Do It Better

'Superfinishing' is a vibratory polishing process for hardened steel parts that gives them a mirror-like finish as smooth or smoother than the surface of a ground roller bearing. Racers take advantage of superfinishing to reduce friction and eliminate the need to 'break-in' new gearboxes. We do it 'in house' to support our manufacturing, so we can usually deliver new gears, shafts and shift forks from stock saving you the hassle, waiting, and extra shipping your friends may have encountered elsewhere. And unlike acid-accelerated alternatives like 'REM', the water-based process we use is eco-friendly.

Aluminum is the most common for automatics and front wheel drive manuals. Cast iron for most rear wheel drive manuals. All transmissions will have steel, stainless steel and brass as well.

Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It is of a higher viscosity to better protect the gears and usually is associated with a strong sulfur smell. The high viscosity ensures transfer of lubricant throughout the gear train. This is necessary since the devices needing this heavy oil do not have pumps for transferring the oil with only a portion of the lowermost gears bathed in an oil sump.
