ARP Head Stud Kit for Ford Focus RS MK3

Introducing the ARP Head Stud Kit for the Ford Focus RS MK3, a custom-made solution designed to elevate the performance and durability of your 4-cylinder engine. This kit is the ultimate choice for enthusiasts seeking the best stud setup available in the market today. Crafted from premium quality heat-treated 8740 chrome moly steel, these studs are engineered to withstand the demands of high-performance engines.
  • Manufactured with premium 8740 chrome moly steel for superior strength and durability.
  • Heat-treated for 360° penetration, ensuring maximum performance and reliability.

Advanced Manufacturing Process

The ARP Head Stud Kit stands out due to its advanced manufacturing process. Each stud is placed vertically in special racks and heat-treated to guarantee 360° penetration, a method far superior to batch treatments. After heat-treatment, the studs are shot-peened to remove surface irregularities and then undergo a centerless grinding process to ensure perfect concentricity. This meticulous process involves about ten machining steps for an exceptionally straight part.
  • Heat-treatment and shot-peening for enhanced surface quality and fatigue strength.
  • Centerless grinding for perfect concentricity and exceptional straightness.

Superior Nut Design for Precision Fit

ARP takes precision to the next level with the nut design of this stud kit. The nuts are manufactured through a multi-step process, blanking the hex and 12-point nuts, followed by CNC-threading with an accuracy of .001K, which is five times higher than the aerospace standard. This ensures an exceptionally close-tolerance fit between the bolt/stud and nut, providing a secure and reliable connection.
  • Multi-step nut manufacturing for a precise and secure fit.
  • CNC-threading with .001K accuracy for unparalleled precision.
This ARP Head Stud Kit is not just a replacement part; it's a performance-enhancing upgrade for your Ford Focus RS MK3. With its superior materials, advanced manufacturing process, and precise engineering, it is the ideal choice for those who demand the best. Upgrade your engine today and experience the difference that ARP can make.
