This is the exact CNC'd 6061 valve spring compressor setup we use in-house at Fab9 Tuning to assemble our Duratec and MZR cylinder heads. After extensive testing during engine builds, we found this compressor system works exceptionally well on Mazda Duratec platforms, making valve spring installation and service dramatically easier and safer compared to traditional universal compressors.

This tool offers excellent geometry, smooth operation, and superior control when working with uprated valve springs commonly found in high-performance Duratec applications.

Whether you're replacing valve stem seals, installing upgraded springs and retainers, or assembling a complete performance cylinder head, this tool helps streamline the process while minimizing the risk of slipping or damaging components.

Fab9 Tuning now offers these compressors individually and as part of our complete engine assembly tool kits.
