The ACL Race Series Connecting Rod Bearing Set for BMW N63 and S63 engines is built for powerplants that live under relentless pressure. When twin turbos push deep into boost and the crank spins hard through heat and load, factory bearings can fall short. ACL Race bearings are made for that breaking point—the moment when strength, precision, and oil control decide if your engine holds or gives in.

Each bearing is crafted with ACL’s tri-metal construction: a hardened steel backing for stability, a copper-lead layer for superior load handling, and a precision overlay that maintains a consistent oil film under intense heat. This design minimizes friction and wear while keeping oil pressure steady across every crank revolution. It’s a setup proven to protect against the extreme stress that tuned and high-performance BMW V8 engines experience.

The ACL Race Series material is trusted across motorsport builds for a reason—it offers exceptional fatigue resistance, stability under load, and predictable oil control at high RPM. These bearings maintain tight clearances, helping your N63 or S63 deliver smooth power and consistent performance during extended pulls, track sessions, or daily street abuse.

Designed as a direct-fit replacement for BMW’s twin-turbo V8 engines—including models such as the 550i, 650i, 750i, M5, M6, X5 M, and X6 M—installation is straightforward and precise. No machining, no modification—just the perfect match for OEM geometry with the durability of motorsport engineering.

For anyone running a tuned, boosted, or track-focused N63 or S63, ACL Race Series bearings are an essential safeguard. They reinforce the bottom end, keep oil control consistent, and deliver peace of mind under pressure. Built for engines that don’t take it easy, they’re the quiet strength behind every hard pull and every redline hit.

FEATURES

Performance-built upgrade: ACL Race Series bearings offer a significant strength and durability improvement over BMW’s standard rod bearings, ideal for high-output twin-turbo N63 and S63 engines.
Engineered for BMW V8 performance: Specifically designed to handle the high boost pressure, temperature, and load seen in turbocharged N63 and S63 engines, maintaining consistent lubrication under demanding conditions.
Precision OEM fitment: Manufactured to strict factory tolerances, ensuring perfect oil clearances and reliable crankshaft stability across all RPM ranges.
Tri-metal race-grade construction: Built with a hardened steel backing, copper-lead intermediate layer, and precision overlay for outstanding load capacity, fatigue resistance, and long-term durability.
Improved bearing-to-housing contact: The non-tin flash finish enhances surface grip, minimizing distortion and maintaining stability under extreme heat and continuous load.
Proven under high-stress conditions: Track-tested and trusted in tuned and endurance applications, providing lasting protection and reliability when boost, RPM, and temperature push beyond factory limits.

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content. Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
