Volvo Penta Splined Sleeve 875183

The Volvo Penta Splined Sleeve 875183 is a genuine OEM driveline coupling component designed to connect and transfer rotational power between the engine and sterndrive input shaft. This precision-machined sleeve features internal splines that engage with the drive shaft, ensuring smooth and efficient torque transmission in Volvo Penta sterndrive systems.

Built to exact OEM tolerances, this sleeve is critical for maintaining proper alignment and minimizing wear within the driveline assembly. It is commonly used in older Volvo Penta sterndrive models and is a key component in extension shaft and upper gear housing assemblies.
