Engine Variable Timing Sprocket (a.k.a. Cam Phaser)

Think TechSmart First: Direct Fit

The Problem: When the unit's movable sprocket fails, the check engine light will turn on and the vehicle may experience rough idling, poor drivability, and valve train noise.

Our Response: To make installation easier, TechSmart’s Engine Variable Timing Unit (a.k.a. Cam Phaser) was engineered to be a perfect fit for the damaged OE unit. 

TechSmart Tip: To make install even easier, pick up TechSmart’s Q21002 Cam Gear Wedge Tool. Made from high-durometer polyurethane, the custom tool locks the sprocket in place.  Also, while you’re optimizing the unit, keep in mind that TechSmart also offers the L53001 Variable Valve Timing Solenoid.
