COVID-19: We ask for your understanding as you may experience delivery delays.
This is an optional HPI 5x9x2mm Silicone O-Ring Set, and is intended for use with the HPI Blitz and Firestorm family of trucks. These silicone O-rings provide a better seal than the stock X-Ring type seals (HPI86898) that are included as standard equipment, to help seal the Blitz and Firestorm gear differentials from dirt and leakage for increased lifespan between re-builds.
