Flash Point Racing 16mm Brass Damper Piston. These 1.45mm 5 hole pistons are unique in that they are machined from brass to slow down the piston speed and help to make the car easier to drive and more consistent. An o-ring around the piston helps to prevent oil blow by as the piston travels through the shock body. The 5 hole pistons are recommended for bumpy low grip surfaces. These pistons can be used in any vehicle that uses a 16mm shock, but the 2.6mm center hole for the shock shaft may need to be drilled out to fit some applications.
NOTE: Hot Bodies and Losi vehicles require that the user ream out 2.6mm center hole to fit the shock shaft.
