Robinson Racing 32P Pinion Gear (13T)

Simply put, these 13 tooth, 32 pitch Robinson Racing steel pinion gears are the best that you can buy for a Tamiya Clod Buster or Bull Head monster truck. I have been using them in my trucks since day one, including in my very first Clod Buster that I bought when Tamiya first released the truck in 1987. I still have that truck, though it has been completely modified over the years, and it is still using these pinion gears from Robinson Racing.

Take it from someone that has many years of experience with Clod Busters and Bull Heads. Do not, do not, DO NOT use the stock aluminum pinion gears that Tamiya supplies in the box. They are made from ultra soft aluminum that seems more like butter and they wear down very quickly, even when using them with the stock 540 motors. Just spend a few bucks and build your Clod Buster or Bull Head right from day one and replace those stock Tamiya pinion gears with a pair of these steel pinion gears from Robinson Racing. (Also throw in a full ball bearing kit too when you first assemble your truck.) They will last an extremely long time no matter what abuse you put your truck through.

All too often I see people modify their Clod Busters and Bull Heads but they still use the stock Tamiya pinion gears. There are better ways to save a few bucks on than that in my opinion. For the record, if the stock Tamiya gearcases are used without adjustable motor mounts, the Clod Buster and Bull Head require one pair of 13 tooth, 32 pitch pinion gears - one per gearcase.

Just bite the bullet and get two of these Robinson Racing steel pinion gears and then you will not ever have to worry about pinion gear wear in your truck for many years.
