A common failure among S54 engines lies within the Cam Gear Bolts, which are prone to breaking, backing out, and shearing, even on low-mileage engines. Symptoms include rattling or ‘knocking’ from the top end of the engine or even catastrophic piston to valve contact.
Replace failure-prone stock bolts before it's too late!
Our S54 Cam Gear Bolt Kit replaces the stock bolts that fasten the cam gears to the camshafts.
Kit includes:
(12) 12.9 Uprated Inner Bolts
