NOVA Gudgeon / Piston Pin .21 (13.8mm)

NOVA Gudgeon / Piston Pin .21 (13.8mm) 

NV-1002002 NOVA Gudgeon / Piston Pin .21 (13.8mm)

Replacement steel gudgeon pin, for use with some of the NOVA .21 nitro engines, and all of the NOVA .24 engines.

If your .21 NOVA engine uses a flat piston, as per earlier generations, you should need the 13.8mm piston pin (NV-1002002). If your .21 NOVA engine uses the later generation concave or convex piston, you will likely need a 13.5mm piston pin (NV-1002004).

ALL of the NOVA .24 engines should require the longer 13.8mm piston pin (NV-1002002).

Despite this advice, we strongly recommend measuring your original pin prior to purchase and subsequently installation with a digital calliper, to determine if you require the 13.5mm or 13.8mm version.
