The Serpent 903777 XLV Shock Piston lets RC riders make controlled damping changes without guesswork. This four-pack of single-hole pistons helps you tweak oil flow and compression characteristics to suit rough trails or hard-packed circuits.
With a focused single-hole geometry, the XLV piston smooths oil movement and offers a consistent feel from lap to lap. That predictability makes setup changes more effective when swapping springs or trying new shock oils.
These pistons are useful across a wide range of shock designs, making them a practical upgrade for racers and bashers alike. Fitting them can reduce understeer and help maintain momentum through technical sections.
