These locks are designed to be used with retainers and valves with a short tip. Be sure that the locks that you purchase are correct for your retainer design. Please review the specs below to make sure these are a proper match for your valves and retainers. You will see some technical links at the bottom of the page to help you select the proper part for your application. If you have any questions, please contact us before ordering. We sell valve locks in sets of eight because many modern race engines use a combinations of valve stem sizes and some engine builders use different install heights on exhaust and intake valves. Therefore, you are purchasing 16 pieces or 8 pair. This will allow you to select the optimum locks for your engine application.
Here are the specs for these Valve Locks:
|Material||Machined Titanium Alloy|

Consider the following benefits of titanium locks:
◊ Lighter Weight - save approximately 4-5 grams per pair
◊ Superior Valve Stem Fit - precise .0007" interference fit and titanium alloy’s high coefficient of friction result in NO relative motion- hence, no galling or wear of valve stem
◊ No Valve Tip Stress - special design “locks” the valve stem in the proper location – below the groove
◊ Longer Life - superior fit results in less wear and extended service life
◊ 100% CNC-Machined - unparalleled surface finish and tolerances
◊ Compatible with titanium and steel valves and retainers
