❓ FAQs
Do I need upgraded springs for a tuned 1KD?
Yes — once boost and RPM exceed certain levels, upgraded springs prevent valve float and protect the valvetrain.
Are these drop-in replacements?
Yes, they are designed as direct replacements for OEM springs in 1KD & 2KD heads.
What boost/RPM are they rated for?
They are engineered to safely handle high-boost diesel builds (45+ PSI) and elevated RPM with oversized cams.
Do I need to modify retainers or seats?
No — they are compatible with OEM retainers and seats. Professional installation is recommended.
