Key item features

  • 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.
  • 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.
