The gears are somewhat similar to the Warn , I have different ratios for my winches but the basics are very similar
Here are the Warn M8000 gears.

and this is the Gear set for the TITAN 10,000lb

Warn uses a Bronze bushing for the Sun Gear i use a Bearing My ring gear is a lot heavier than Warn ( this can be both good and bad as yes it has a lot of strength but it does make i a little harder to freespool ) The solenoids are similar to the Albrights except the contacts are Silver cadium oxide coated to eliminate any arcing when operated.
What size did you want I stock 12v but i can also get 24v if that is any use to you.
Cheers.
