Comp Cams GM LS7 & Gen V LT Trunnion Upgrade Kit

If you're working on a GM LS7 or Gen V LT engine, this trunnion upgrade kit from COMP Cams is a smart move to improve the reliability of your rocker arms. It replaces the stock needle bearings with full complement roller trunnions, which are a must-have when you're upgrading to a more aggressive camshaft or stiffer valve springs. This kit is designed to fit a range of popular GM vehicles, including the Chevrolet Camaro, Corvette, and Silverado, as well as GMC Sierra and Yukon models.

The kit includes heavy-duty billet steel rocker arm trunnions and high needle count roller bearings, along with retaining rings. This upgrade converts your OE rocker arms into a captured trunnion setup, offering better stability and stiffness without changing the stock geometry. Many customers find they can complete this upgrade in about 30 minutes using a simple C-clamp or a bench vise, making it a straightforward job for many DIYers.
