Denstoj rocker retainers were born from the frustration of blown engines and the lack of a reliable solution to valvetrain failures in modern performance engines.

Built by engineers with real-world experience at companies like Toyota, GM, and Tesla, Denstoj solutions are designed to keep your engine alive at the limit. Denstoj specialise in precision-machined valvetrain components — including their flagship rocker retainer kits and solid lifters for high-RPM applications.

Denstoj products are trusted in platforms like the GR Yaris (G16E-GTS), Subaru FA20 & FB25, and the Nissan SR20. They’re proven on track, and built to last on the street.
