Super Duty 10 Degree 11/32" Valve Locks

Shown here is our 10 degree Super Duty valve locks. These are a huge, extremely beefy valve lock which has a wider angle of interference than a standard 7 degree lock. These are fully machined (not stamped) from a super tough fatigue resistant alloy. These are recommended these for any cams over .460" lift. These fit 11/32 valve stems, which can be found on most aftermarket aluminum heads (such as our Stealth heads or Edelbrock RPM's,) and they work great (and must be used with) our 10 degree retainers, part number 145-1003, which can be found on our Valve Retainers page. We highly recommend upgrading to these for extra insurance. These are supplied in a set of 32, enough to do one complete engine.
