Product Details

ARP's 233-5201 main cap fastener kit delivers the strength and reliability professional engine builders demand for high-performance and competition applications. This comprehensive 4-bolt main kit helps eliminate main cap walk and fretting while protecting the threads in your engine block.

Key Features:

  • Forged from premium 8740 chrome moly steel for exceptional strength
  • Heat-treated in-house to 200,000 psi tensile strength
  • Precision J-form threads rolled after heat-treat for 1000% greater fatigue life than conventional fasteners
  • Generous under-head radius design for maximum reliability
  • Includes hardened parallel-ground washers for proper load distribution
  • Professional-grade fasteners meeting the exacting standards of competition engine builders

ARP's post-heat-treat thread rolling process creates threads that are significantly stronger and more fatigue-resistant than fasteners threaded before heat treatment. Each component is manufactured to precise tolerances to ensure consistent torque values and optimal clamping force, making this kit an essential upgrade for any performance or racing engine build.

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
