The 4.7L V8 uses hydraulic timing chain tensioners that ratchet outward the instant chain tension is lost, which makes camshaft work risky without the right tool. This timing chain wedge slips between the chain and the tensioner to hold everything in place, so the piston cannot extend while you remove or swap camshafts. It keeps valve timing intact and saves you from a full timing job on Chrysler, Dodge, and Jeep 4.7L engines.

• Locks the timing chain against the hydraulic tensioner to stop ratchet and piston extension
• Lets you remove or swap camshafts without losing valve timing
• Installs and removes with a 1/2 in. square drive ratchet or breaker bar
