ARRMA ARA716034 O-Ring 7.8x2.2mm (4)

The ARRMA® ARA716034 O-Ring 7.8x2.2mm are genuine OEM replacement o-rings for compatible ARRMA vehicles, sold in a pack of 4. O-rings are critical sealing components used throughout ARRMA differentials and drivetrain assemblies — they prevent differential fluid from leaking past housing joints and caps, maintaining correct differential fluid levels and lubrication. Worn, damaged, or flattened o-rings result in differential fluid leaks, leading to dry differentials, increased wear, and inconsistent handling. Replacing with correct OEM-spec o-rings restores proper sealing and differential performance. The 7.8x2.2mm size is specific to compatible ARRMA differential applications — verify fitment with your specific model before purchasing.
