ACL Race Series Engine Bearings - 7M2428H-.50

If you're pushing your Nissan GTR, Skyline R32, R33, or R34 to the limits, you know the importance of reliable engine components. The ACL Race Series Engine Bearings (part number 7M2428H-.50) are engineered for high-performance applications, ensuring your engine can handle the rigors of high RPMs without compromising on durability.

Why Choose ACL Race Series Engine Bearings?

These bearings are not just another aftermarket part; they are the result of advanced design, metallurgy, and engineering. They are specifically crafted to meet the demands of serious drivers who expect nothing but the best from their engines. Here’s what makes these bearings stand out:

• High strength overlay plate with reduced thickness enhances fatigue resistance, perfect for those extended track days.
• Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring they stay securely in place.
• Increased crush improves bearing retention, giving you peace of mind during high-stress driving conditions.
• Elimination of flash plating on the back of the bearings optimizes heat transfer and grip, crucial for performance applications.
• Enhanced eccentricity compensates for bore distortion at high RPM, promoting the formation of hydrodynamic oil films.
• 3/4 grooved main bearings maximize load-carrying surface area and oil flow to the connecting rod bearings.
• Tight, consistent wall tolerances maintain precise clearances for optimal performance.
• Enlarged ID chamfers on bearing edges accommodate larger fillet radii on performance crankshafts.
