BMW S65 V8 Rod Bearing Set

Manufacturer Part Number: 8B1580HX-STD 

Give your high-revving S65 engine the reliable foundation it needs—whether you’re chasing lap times on track or simply enjoying spirited drives. Designed to address the known weak point in the S65’s bottom end, this rod bearing set uses a proven Tri-Metal lead/copper construction for better embeddability, superior load handling, and overall increased durability. If you demand long-term peace of mind and optimal engine performance, consider these rod bearings an essential upgrade for your M3.

  • Lead/Copper, Tri-Metal design: Tri-Metal, lead/copper are considered the world’s best bearings. The steel backing is coated with copper and then topped with a soft lead. The lead is embeddable, meaning small particles can embed themselves in the lead without causing any damage to the crankshaft. Look in the best automotive engines, and you’re likely to find a Tri-Metal bearing design.
  • High-strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
  • Increased crush for improved bearing retention
  • Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
  • Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
  • Tight consistent wall tolerances to help you maintain consistent clearances.
  • Enlarged ID chamfers on bearing edges were required to accommodate large fillet radii on performance crankshafts.

Why Choose These Rod Bearings?

  1. Track-Proven Reliability: The S65 engine’s high rev limits demand superior bearing protection. A Tri-Metal construction helps safeguard against premature wear and bearing failure.
  2. Expertly Engineered: From materials to machining, each bearing is crafted for consistent, precise fitment, ensuring optimal oil clearance and extended engine life.

Upgrade your S65 with a rod bearing set built to perform under the most demanding conditions.

Great product, fantastic service, and an all around awesome group of guys. My car is a daily driver and I couldn’t afford a long downtime. When I called to check on ETA, they offered to send me the parts with expedited shipping at no additional cost. Their parts are top notch, warranty is great, and the cost is more than fair. Would highly recommend M Power!
