Product Details

ARP Pro Series main studs provide critical upgrades for high-performance Subaru WRX engines by eliminating main cap walk and fretting while protecting valuable engine block threads. Designed specifically for 2002-2006 Subaru WRX models with EJ20 and EJ25 engines, these studs are engineered to maintain precise main bearing alignment under extreme loads and high-RPM operation.

Key Features:

  • Manufactured from premium 8740 chromoly steel for superior tensile strength
  • Black oxide finish for corrosion resistance
  • Precision CNC-machined threads for accurate torque loading
  • Eliminates main cap movement and fretting damage
  • Protects engine block threads from damage during installation and removal
  • Allows for more accurate and consistent clamping force compared to OEM bolts
  • Includes premium-quality hardened washers and ARP Ultra-Torque fastener assembly lubricant

ARP main studs are essential for turbocharged builds, race applications, or any engine rebuild where reliability and precision are critical. Each kit is manufactured in ARP's own facility using proprietary heat-treating processes and strict quality control standards to ensure consistent performance and durability.
