This 3 Bolt 4 Pole timing chain gear is used when converting from a 1 bolt camshaft to 3 bolt camshaft.
Stock replacement lower timing chain gear for all LS engines except LS7 and LS9.
These high-quality ARP cam bolts have increased preload clamping force to ensure positive timing gear register. Their increased material strength overcomes valve train harmonics and stress.
