Product Details

The COMP Cams 13706-KIT is a comprehensive stud upgrade kit designed to enhance the strength and reliability of your Ultra Pro Magnum and Ultra Pro Magnum XD rocker arm systems. This kit upgrades your existing rocker arm studs to a robust 1/2" diameter, providing increased clamping force and improved durability under high-performance conditions.

Key Features:

  • Upgraded 1/2" diameter studs for maximum strength and reliability
  • Specifically engineered for COMP Cams Ultra Pro Magnum and Ultra Pro Magnum XD rocker arms
  • Provides enhanced clamping force to prevent stud failure under extreme valve spring pressures
  • Complete kit includes studs, hardened washers, and lock nuts for professional installation
  • Ideal for high-lift camshafts and high-RPM racing applications
  • Precision-machined from high-quality materials for consistent performance

This upgrade kit is essential for serious performance builds where rocker arm stability is critical. The larger 1/2" stud diameter significantly reduces the risk of stud pull-out or failure, making it perfect for aggressive cam profiles and heavy-duty valve springs. Installation requires machining the cylinder head to accept the larger stud diameter.
