ACL Race Series HX Main Bearings (Extra Oil Clearance)

When building a high-performance 4G63 or 4G64 7-bolt engine, managing oil flow and heat is critical. The ACL Race Series HX (Extra Oil Clearance) main bearings are specifically designed to provide that vital additional clearance, allowing for improved lubrication and cooling at high RPMs. These bearings are the preferred choice for tuners looking to push their DSM or Evolution builds to the limit.

Why Choose HX Bearings?

• Extra oil clearance for high-load performance
• Enhanced oil film thickness to prevent metal-on-metal contact
• Superior fatigue resistance under extreme boost
• Precision-engineered for 7-bolt 4G63/4G64 blocks
• Standard size with added clearance for high-output setups

These bearings provide the perfect balance between oil pressure and flow, ensuring your crankshaft stays protected during aggressive driving. The advanced tri-metal design is optimized for high-heat environments, making them essential for turbocharged applications where oil temperatures can skyrocket. By reducing friction and improving heat dissipation, these bearings help extend the life of your engine components. Trust your build to the proven quality of ACL.
