Customer Questions & Answers

  • Question: What does the Retro-Fit Trunion Kit do?

    Answer: The kit enhances the stability and stiffness of the rocker arm, providing improved performance and durability.
  • Question: Does this work with the l76 from the g8 gt?

    Answer: Yes. It works on all LS engines, including rockers with offset rocker.
  • Question: Is it good for racing?

    Answer: While it may provide a smoother idle, it does not directly increase power. However, it offers peace of mind and improved durability for higher lift aftermarket cams.
  • Question: Why do orders not come with stickers?

    Answer: The inclusion of stickers is determined by the company. Stickers may add extra cost, and customers are primarily purchasing parts, not stickers.
  • Question: Would this kit fit a 2002 Silverado with a 6.0?

    Answer: Yes, it is compatible with the 6.0 engine. It is recommended to also purchase the Comp Cams installation tool for easier installation.
  • Question: Does this work with LS3 heads?

    Answer: While it is designed for LS2 heads, it may work with LS3 heads if the width of the rocker arm trunnion is the same. It is recommended to get the trunnion installation tool for a smooth installation.
  • Question: Will this fit my Trailblazer SS LS2?

    Answer: It should fit, but it is recommended to contact Comp Cams directly for confirmation. Using brass bushings instead of roller bearings is not advisable for daily driving.
  • Question: Fit Chevrolet Camaro V6 3.8L?

    Answer: No, the dimensions of the rocker arms on the 3.8L V6 are different, so this kit will not work.
  • Question: Does this product fit the LS2? I have an 05 GTO and I keep seeing that the part number on this item matches the one that fits the LS2.

    Answer: Yes, it fits the LS2. Many customers with LS2 engines have successfully installed this kit.
  • Question: Will this work on LS7? What brand are these?

    Answer: This trunnion upgrade kit is sold by Comp Cams. While it is designed for LS-2, the compatibility with LS-7 may be dependent on the rocker arm pivot point. It is recommended to contact Comp Cams Tech support for a definitive answer.

Comp Cams Rocker Arms Editorial Review

The Comp Cams 13702 Trunnion Upgrade Kit is highly regarded for its quality and performance. It is compatible with various LS engines and provides a smooth and quieter operation. The kit includes machined steel trunnions and 360 degree needle bearings, offering a more reliable and durable solution compared to the stock rocker arms. While it may not necessarily increase power, it provides peace of mind and is a must-have upgrade for LS engine owners. Some customers have noted missing needle bearings, but overall the product is easy to install and delivers excellent results.
