Fits: 1st generation non-hemi Predator engines with 5.5mm stems and slip retainers without keepers.
These are stock size valves but are stonger and more reliable than stock valves. These will not work with the stock keepers so you need to pair these with our DJ-1047 retainers/keepers and DJ-1051 lash caps.
- Intake : 25mm
- Exhaust : 24mm
