Product Details

The ARP 400-3221 is a precision-engineered stainless steel stud kit designed for securing water pump pulleys while providing proper fan spacing. This specialized fastener solution combines a water pump pulley stud with an integrated 1.000-inch fan spacer for proper accessory alignment and clearance.

Key Specifications:

  • Thread Size: 5/16-24
  • Overall Length: 2.250 inches
  • Material: Stainless steel construction for corrosion resistance
  • Head Style: 12-point design for precise torque application
  • Integrated Fan Spacer: 1.000-inch spacing for proper fan clearance
  • ARP Quality: Manufactured to aerospace standards for reliability

ARP fasteners are known throughout the racing and performance industries for their superior strength and consistency. The 12-point head design allows for easier installation in tight spaces with better tool engagement than standard hex heads. The stainless steel construction provides excellent resistance to corrosion from coolant exposure and environmental conditions, making this an ideal choice for water pump installations where durability matters.

This stud kit eliminates the need for separate fan spacers while ensuring proper pulley and fan alignment. Perfect for engine rebuilds, performance upgrades, or restoration projects where quality fasteners are essential.
