FAQ

Tool steel offers high strength with low mass to control valve float at higher RPM and cam lift, reducing risk of retainer failure in performance builds.

For street/tow builds with moderate RPM, use Hamilton 07-S-003 (103#). For higher RPM/competition or big-lift cams, step to 07-S-110 (110#).

Stronger pushrods help prevent deflection in high spring pressures/RPM. Consider Hamilton 07-P-004 for aggressive cams or frequent high-RPM use.

Yes—these retainers cover 1998.5–2018 24V 5.9L/6.7L Cummins applications. Verify your spring choice against your intended RPM and cam specs.

Use a dedicated 24V spring compressor like CPP-9824-VST. Inspect keepers/locks during reassembly and always follow proper torque and lash procedures.
