Precision Engineering for SR20 Engines

When rebuilding your Nissan SR20DE or SR20DET engine, the foundation of your rotating assembly is critical. The ACL Race Series Main Bearing Set (0.25mm Oversize) is engineered to withstand the extreme loads of high-performance driving. Designed for engines that have undergone machine work, these bearings provide the necessary clearance for a precision-machined crankshaft.

Key Features and Benefits

• High-Strength Overlay: Features a hardened steel back for maximum durability under high-RPM conditions.
• Precision Tolerance: Manufactured to exact tolerances to ensure consistent oil film thickness and optimal heat dissipation.
• Enhanced Oil Clearance: Specifically sized at 0.25mm oversized to accommodate reground crankshafts.
• Race-Proven Design: ACL's unique combination of design, metallurgy, and engineering provides superior fatigue resistance compared to OEM alternatives.

These bearings are the gold standard for enthusiasts building reliable SR20 platforms. Whether you are running a naturally aspirated DE or a boosted DET setup, ACL provides the stability your bottom end requires. Ensure your engine build is done right the first time with high-quality components designed for longevity and power. For all your performance engine needs, trust the experts at GGCRACING.
