HPI 87515 Precision Piston 1.4X2 Holes (4pcs)

These Hellfireshock pistons are precision machined from aerospace POM (polyoxymethylene), providing pistons that are harder than normal nylon. This provides for more precise internal shock movement and less friction for smoother suspension movement. The 1.4mmX2 hole size is recommended for the rear shocks of the Hellfire.
