The 5150 AutoSport High-Performance Rod Bearing Kit is designed to solve the well-known rod bearing issues of BMW S54 engines, offering a superior replacement to stock bearings. Our kit includes Calico-coated rod bearings and ARP connecting rod bolts, ensuring long-lasting durability and consistent performance under demanding conditions.

Kit Contents:

Calico-Coated Rod Bearings
ARP Connecting Rod Bolts
ARP Assembly Lubricant

The Calico coating on our rod bearings provides excellent anti-friction and thermal resistance properties, ensuring reliable lubrication even during cold starts and under high-stress conditions. This coating significantly reduces the risk of catastrophic failures, like spun rod bearings, which are common in engines using OEM bearings. The combination of advanced coating and ARP hardware makes this kit ideal for both high-performance builds and daily drivers.

Our bearings have consistently demonstrated superior performance and longevity compared to standard options. Whether you’re pushing the limits with forced induction or simply seeking reliability in daily use, the 5150 AutoSport rod bearing kit is engineered to deliver peace of mind and exceptional performance.

Tech Notes:

- Just as with any bearings, it's crucial to verify tolerances and dimensions prior to installation.

- Given the specialized tools necessary, we strongly recommend seeking professional installation.

- There are no returns available on any engine bearings.

Rod Bolt Installation Instructions:

1. Make sure that there is an adequate chamfer around the bolt hole on the connecting rod bolt hole on the connecting rod cap to clear the radius under the head of the bolt.

2. Use ARP Ultra-Torque Fastener Assembly Lubricant to lubricate the threads of the bolt and the under head of the bolt. Then install the bolts and tighten them hand tight.

3. ARP Recommends using the STRETCH METHOD when tightening rod bolts. Following the instructions for using a stretch gauge,

Stretch M10 bolts to .0075 - .0080

Stretch M11 bolts to .0065 - .0070

4. If you do not have a stretch gauge, torque

M10 bolts to 70 ft-lbs using ARP Ultra-Torque Fastener Assembly Lubricant

M11 bolts to 50 ft-lbs using ARP Ultra-Torque Fastener Assembly Lubricant

5. The connecting Rods should always be re-sized after new rod bolts are installed

6. A log should be kept on the original non-torqued length of each bolt. Bolts that have any permanent deformation or have increased in non-torqued length by more than .001 inch should be replaced.
