Arrowmax AM-931013 O-Ring 4.5x1 Maintenance Pack (10)  [AM-931013]

Seal and Maintain Differentials with Arrowmax O-Rings

The Arrowmax AM-931013 O-Ring pack contains 10 rings sized 4.5x1 for 1/12 and 1/10 scale gear differentials. They are intended as direct replacements for worn seals to prevent leaks.

Routine maintenance advice

Replacing worn O-rings is a simple way to keep diff performance steady between services. Fit fresh Arrowmax AM-931013 O-Rings to avoid oil contamination and preserve consistent torque transfer.

Compatibility notes

These O-rings fit many small-scale F1 and pancar differentials, but always confirm the 4.5x1 dimension before using them in other gearboxes.
