Castle Creations 13T MOD1 Pinion, 5mm Shaft

The Castle Creations Pinion – 13 Tooth – MOD1 – 5mm Shaft (M-CC6508) is a MOD1 pitch pinion intended for use with 5mm motor shafts. It supports MOD1 drivetrains commonly found in powerful RC setups where precise, consistent meshing is important.

A 13T pinion generally offers stronger acceleration and reduced top speed compared with higher tooth counts, allowing fine tuning of gearing to suit track conditions and temperature management.

Suggested Compatibility

• Motors featuring a 5mm output shaft
• MOD1 spur gears used on many 1/8-scale RC cars and trucks
• Castle Creations brushless systems that utilise MOD1 gearing

Setup Tips

• Set gear mesh with a slight amount of backlash for smooth running and to minimise wear.
• Re-check motor and ESC temperatures after any gearing change.
• If your pinion uses a grub screw, apply medium threadlocker to the screw and allow it to cure fully.
