Oversized retaining plates lock camshafts together at top dead center (TDC) on GM 2.8L, 3.0L, and 3.6L DOHC V6 engines
Three-plate set is used to tighten both sets of cams to prevent them from turning while setting timing
Includes 3 plates: one plate is used to tighten one set of cams, two plates are used in conjunction to tighten the second set of cams
Extra-large size prevents valve covers from being installed with the plates in place, protecting the engine from inadvertent damage
