We are proud to start offering our in house built 6, 8 and 10 rib power steering pulleys for the Corvette belt drive. This covers all C5 and C6 applications OTHER than the LS9. The pulley hub bore fits pumps .665" in diameter. This pulley replaces both the plastic and spoked steel design, covered under part numbers 12559890 and 12568997.
Our pulley hub is made of 304 stainless instead of plated steel, or the no hub design used by other suppliers. Pulleys are stocked in black anodize as a standard to keep belt wear on the surface at a minimum and prevent corrosion, but we do keep a small stock of bare on hand as well for custom colors. Kit includes pulley hub, 6 grade 12.9 socket head bolts and pulley shell.
The pulley hub also has the provision for a puller for pump replacement, but is hidden once the pulley shell is installed.
The overall diameter and rib diameter are the same as an OEM pulley. Larger and smaller ones can be made as a custom item, please contact us to purchase this option. The rib section normally is 6.150" and the overall diameter is 6.45".
These are stocked in 6 and 8 rib, 10 rib variant is made to order and can have a few weeks lead time.
