Watch in action

Reliable Clamping for Early Coyote Engines

The 2011-2012 Ford Mustang GT and Boss 302 introduced the world to the legendary Coyote 5.0L engine. To ensure these engines perform reliably under increased load, the ARP 256-4702 Head Stud Kit is the preferred choice for enthusiasts. These studs provide a significant upgrade over factory head bolts, ensuring that your cylinder heads remain securely fastened regardless of the power output.

Key Features of the 256-4702 Kit

  • Precision-machined from 8740 chromoly steel.
  • Designed for a perfect fit on 2011-2012 Coyote 5.0L engines.
  • Prevents head gasket failure by ensuring uniform clamping force.
  • Reusable design allows for easier engine maintenance and rebuilds.

Whether you are adding a cold air intake, headers, or a full supercharger system, your engine needs the stability that only ARP hardware can provide. These studs are heat-treated to ensure maximum strength and are finished with a black oxide coating to prevent corrosion. By upgrading your head studs, you create a more stable environment for your engine, allowing for more aggressive timing and higher boost levels. This kit is essential for anyone looking to unlock the full potential of their early-model Coyote engine. Don't settle for factory hardware when you can have the peace of mind that comes with industry-leading performance parts. For the best selection of engine hardware for your Mustang, visit GGCRACING.
