Product Details

ARP's 146-5401 main stud kit is engineered to eliminate main cap walk and fretting while protecting your cylinder block threads from damage. Designed specifically for Jeep 4.0L inline 6 engines with 2-bolt main configurations, this precision-manufactured stud kit provides superior clamping force and reliability compared to factory bolts.

Key Features:

  • Rated at 190,000 psi tensile strength for maximum holding power
  • Meets or exceeds aerospace-grade material specifications
  • Prevents main cap movement and fretting under high-stress conditions
  • Protects engine block threads from damage during installation and removal
  • Precision-manufactured for accurate torque loading and consistent clamping force
  • Application-specific design for Jeep 4.0L inline 6 engines with 2-bolt mains

ARP main studs are manufactured from premium-grade materials and heat-treated to exacting standards, ensuring consistent quality and performance. The superior thread engagement and materials provide a more reliable fastening solution than OEM hardware, making this kit ideal for stock rebuilds, performance applications, and high-stress racing environments.

Some parts have very limited information such as left or right or if ball joint is included and so on, other than that the prices and shipping seem fair and the web site is easy to navigate. Thanks Dave

Can't wait to see how it fits. Thanks

Great price even after shipping cost added I have installed them in my truck bed behind the cab, Looks like it goes all the way across like a full across the bed box, but I can reach everything from the ground. Love it.
