Lightened billet steel duplex timing set for standard to lightly tuned engines. Upgrading to a duplex timing system can really help out power levels by keeping the camshaft and ignition timing spot on. This set is a great choice for someone upgrading the cam without wanting to spend big bucks on a lightweight billet or adjustable timing setup, but still getting the job done. This billet version is suitable for high RPM, unlike the cheaper cast variant.
 
Fitting a duplex timing set requires countersinking the front plate for the supplied countersunk screws, as well as knocking out the bump on A+ timing covers. Failure to do this will result in major engine damage!
