Sealed Power A-Series Rod Bearings
Sealed Power A-Series rod bearings can actually polish the journals on your crankshaft. That's because there's a small percentage of silicon mixed in with the aluminum and tin that make up the bearing-surface alloy. The silicon is there for wear resistance, but its toughness actually smoothes the journals of a crank with a surface that hasn't been optimized! This special surface alloy is laid over a high-strength 1010 steel backing and delivers improved seizure and corrosion resistance, as well as better wall variance control. It also helps to minimize debris embedding, which can score the crank's surface. Order the replacement bearings designed for your vehicle make and engine application.

ACDelco V-Ribbed Serpentine Belts
ACDelco V-ribbed serpentine belts resist the penetration of water, acids, and ozone--plus, they provide broad temperature tolerances. Their patented advanced technology design incorporates EPDM rubber, which stays soft and pliable longer than traditional belt materials. Neoprene and certain grades of rubber can harden, causing unwanted squealing and a shorter belt life. The flexible construction of these serpentines allows each belt to withstand many topside and backside bends. ACDelco offers their V-ribbed replacement belts in various lengths, widths, and rib quantities for a wide range of fitments.
