- Precision Machined Trunnion: Designed by CHE for high-performance applications, this trunnion is built to handle the abuse of aggressive cam profiles, high RPMs, and extended engine loads without failure.
- Bronze Bushing Technology: Replaces the stock needle bearings with durable bronze bushings that eliminate the risk of bearing failure and catastrophic valvetrain damage during high-rpm use.
- Increased Valvetrain Stability: Reduces rocker arm movement and deflection under load, improving valve control, engine efficiency, and overall horsepower potential across the RPM band.
- Perfect for High-Stress Builds: Whether it’s for drag racing, drifting, or high-boost street performance, this CHE 4290 trunnion kit delivers superior durability and consistent results in the harshest environments.
- Sold Individually – Not a Full Kit: This listing includes one single CHE 4290 trunnion with bushings and clips—ideal for replacing a damaged unit or upgrading one rocker arm without buying a complete set.
