When you service your Kyosho Surfer 4, keeping the hull and components watertight is essential. The Kyosho ORG19BK O-Ring set contains four black replacement seals made to restore watertight integrity and protect internal parts from moisture.
These black O-rings are produced to match the Kyosho Surfer 4 sealing points for a snug fit and dependable sealing. Replacing worn O-rings on a schedule helps avoid water ingress and reduces corrosion risk on drive and electronics parts.
For enthusiasts who run the Surfer 4 often, inspect O-rings after heavy sessions or any impact that may compress or nick the seal. Swap them out at the first sign of flattening, cracking, or leakage to maintain peak reliability.
