ACL Bearings 8B1808H-.25 Race Series Rod Bearing Set .25mm Undersize Hemi

The ACL Bearings Race Series 8B1808H-.25 is a high-performance connecting rod bearing set engineered for Chrysler, Dodge, and Jeep Hemi V8 engines. This set includes 16 bearing halves (8 pairs) designed for .25mm (0.010") undersize crankshaft journals, making it ideal for rebuilt or performance crankshafts.

These premium tri-metal bearings feature a sophisticated design that combines superior materials with race-proven engineering. The high-strength overlay plate with reduced thickness delivers improved fatigue resistance, while the hardened steel backing provides exceptional support for the bearing lining and assists with retention in the connecting rod housing.

Performance Features:

• Tri-metal construction designed to withstand high RPM conditions
• Hardened steel backs on all rod bearings for improved support and retention
• Increased crush for superior bearing retention in the housing
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip
• Tight, consistent wall tolerances to maintain precise bearing clearances
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius crankshafts

ACL Race Series bearings are standard components in championship-winning engines across motorsports disciplines, from NASCAR and NHRA to sport compact drift racing. The unique combination of metallurgy, design, and engineering provides these bearings with the endurance and capability to perform in extreme conditions where standard bearings cannot.

Fits Chrysler 5.7L (345ci) Hemi V8, 6.1L (370ci) Hemi V8, 6.4L (392ci) Hemi V8, and 6.2L supercharged Hemi V8 engines. Perfect for high-performance street builds and dedicated race applications.
