• Reduces friction and abrasive wear through advanced dry film lubrication
• Provides intermittent dry lubrication during oil starvation conditions such as cold starts
• Increases load carrying capacity from standard 12,000 PSI to 180,000 PSI
• Can reduce oil temperatures by 15-20°F for improved thermal management
• Not affected by dust or dirt contamination
• Coating thickness of 0.00025" to 0.00030" (6 to 7.5 microns)

Race Series Features:

• Hardened steel backing improves bearing support and retention in the housing
• Tri-metal construction combines copper-lead alloy with steel backing and electroplated babbitt overlay
• Elimination of flash plating improves heat transfer and maximizes grip in the housing
• Tight, consistent wall tolerances help maintain proper clearances
• Enlarged chamfers accommodate large fillet radius on performance crankshafts
• 0.010" oversize for reground crankshafts
