Product Details

The COMP Cams 13702-KIT Trunnion Upgrade Kit is engineered to replace the factory needle bearing trunnions in GM LS1, LS2, LS3, and LS6 rocker arms with a more durable, high-performance design. Factory LS engine trunnions are a known weak point that can fail under high-RPM or high-spring-pressure conditions, leading to catastrophic engine damage. This upgrade kit eliminates that vulnerability with precision-machined components built for reliability.

Key Features:

  • Direct replacement for OEM LS1, LS2, LS3, and LS6 rocker arm trunnions
  • Upgraded bearing design provides superior strength and durability
  • Prevents trunnion failure under high valve spring pressures and RPM
  • Precision-manufactured to COMP Cams' strict quality standards
  • Ideal for performance builds, aggressive cam profiles, and increased valve spring loads
  • Complete kit includes all necessary components for rocker arm rebuild

This trunnion upgrade is essential for any LS engine build running aftermarket camshafts, upgraded valve springs, or operating at elevated RPM ranges. The kit provides peace of mind and long-term reliability for street performance, racing, and high-performance applications. Installation requires disassembly and reassembly of rocker arms with appropriate tools and mechanical knowledge.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !
