Blew a shock and need to rebuild. My question is I got some Team Losi Silatech Competition Grade shock oil in 20w flavor.
I have the stock Traxxas Ultra Shocks and need to know what piston head to use with 20w oil.
I'd use the one hole piston because that oil is lighter than the stock oil. You probably could use the two hole piston, but you would need stiffer springs I would think.
