Billet Drop-In Oil Pump Upgrade

The Ultimate Oil Pump Upgrade Kit for BMW S5X and M5X Engines
 
Help prevent oil pump shaft failures and safeguard your engine with this complete oil pump upgrade kit. Designed to bolt directly into your original pump housing, this kit offers superior strength and reliability, going beyond basic shaft upgrades to provide the most robust solution available. 
 
Key Features
Billet Front Cover: Allows for a stronger and more durable shaft design to eliminate common failure points (Where the sprocket connects to the shaft)
Hardened Steel Oil Pump Shaft
Brand New Oil Pump Rotor: Unobtanium brand new OEM rotors. 
New Oil Pump Sprocket: Laser-cut and hardened.
New O-Rings: Includes O-rings to rebuild the internal pressure regulator and replace the O-ring on the oil pickup tube.
 
This kit is meticulously designed to address the root causes of oil pump failures, providing a durable, long-term solution for enhanced performance and reliability. A key feature of this upgrade is the 4x sprocket bolt design, which securely fastens the sprocket to the oil pump shaft to prevent the common issue of the oil pump nut loosening or falling off—an unfortunate issue with the OEM system. 
 
Another major cause of oil pump failure is caused by excessive chain slack cause by stretched-out chains, which can lead to tooth skipping. This places significant stress on the sprocket, often resulting in shaft failure where the sprocket mounts to the oil pump shaft. To combat this, we strongly recommend replacing the oil pump chain during the upgrade. A new chain eliminates slack, reduces the risk of skipping, and ensures the entire system operates smoothly and reliably at high RPM's. The tensioner kit we offer furhter improves the system reliability. The massive oil pump shaft is much more resistant to increased pressure. 
 
Compatibility
This kit replaces the front assembly on the following BMW engines:
