3-bolt Timing Chain set includes the following:
  1. 3-bolt cam sprocket (58X)
  2. Crank sprocket
  3. High Performance Timing Chain
  4. Timing chain dampener 
  5. ARP cam bolts 134-1003
 
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 valvetrain harmonics and stress.
 
Production LS2 and newer Timing Chain Dampener, helps dampen chain whip and extend chain life. Will not fit LS1, LS6 or 2006-earlier truck blocks.
Chevrolet Performance timing chain dampeners replace your old ones with a perfect fit. Rapid deceleration from higher rpm can cause your timing chain to whip back and possibly fail.
Restrain the whip and extend chain life, with Chevrolet Performance timing chain dampeners in place.
