Main bearing STD Chevrolet 1985-2004 173, 191, 207 V6 ACL

ACL Race bearings are designed to work in the most extreme conditions and the most strained engines.
Thanks to many years of experience in the production of bearing panes, each set is ideally suited to the engine.
The advanced technological process allows the bearing to adjust to the deformations arising at high revs and helps in the production of hydrodynamic oil films.
This technology, in combination with advanced cup geometry, makes them ideal for heavily strained engines.</ P>

Most panes are also available in several other dimensions:</ p>

• STDX -0,025 mm (looser than nominal)</ li>
• STD +0,000 mm (nominal)</ li>
