THE 2.5TFSI TSFI Billet Main Bearing Caps

 Audi 2.5 DAZA & DNWA Engine

 THE steel main bearing blocks are developed for extremely powerful DAZA & DNWA engines.

The material is a tempered and heat-treated tool steel with a tensile strength of approx. 1100 N / mm2 and very good machinability.

As can be seen in the pictures, the laser engraving on the contact surface of the aluminum block was taken from the original part in order to prevent the bearing blocks from shifting sideways.
