⚠️ Upgrading to a Front Cam Sensor? Read This First

If you’re using an aftermarket camshaft in your 24x LS engine, we recommend converting to a front-mounted LS2-style cam sensor. Some aftermarket cam cores may cause signal dropout with the rear cam sensor, leading to random misfire codes.

To avoid this, convert during your build using:

• GM LS2 timing cover + cam sensor kit (PN 12633906)

• 3-bolt 24x timing gear (PN 12576407)

This ensures rock-solid spark timing and long-term reliability.
