Product Description:
Lead Time - Signal kits (as they are used in LS PCM kits) can have a lead time estimate of 2-3 weeks. If we have the inventory available base on queue these can ship quicker.
The Torqhead 24xLink Signal Kit provides the core mechanical components needed to generate the 24x crank and 1x cam signals required for a Gen 3 LS PCM conversion on 1992–1997 LT1/LT4 engines. Designed as a direct replacement for the Optispark, this kit delivers proven accuracy, fast starts, and turn-key reliability without removing the timing cover. Perfect for factory LT1/LT4 builds or aftermarket ECU conversions (Holley, FAST, etc.), the 24xLink Signal Kit is fully bench-tested to 10,000 RPM before shipping.
What’s Included
• 24xLink sensing unit with adjustable crank sensor mount (patent pending)
• Keyed billet crank hub with integrated 24x dual-track reluctor
• Woodruff key for crank hub
• ACDelco OEM 24x dual-track crank sensor
• ACDelco OEM 1x cam sensor
• Water pump gaskets
• Installation instructions
Key Features
• Direct plug-in replacement for the Optispark housing
• Market-leading crank sensor performance
• Dual-track 24x reluctor design for high accuracy and fast starts
• Adjustable crank sensor position and air gap for guaranteed signal quality
• Works with all 1992–1997 LT1/LT4 engines, timing covers, and single/double-row timing chains
• Cam reluctor tolerances are factory-set during manufacturing
• 100% assembled and bench-tested to 10,000 RPM before shipment
How It Works
The 1x cam signal comes from the included OEM sensor inside the 24xLink sensing unit, reading a reluctor driven directly from the camshaft. The 24x crank signal is generated by the dual-track reluctor mounted externally on the billet crank hub. This design matches the LS factory approach, providing the highest-quality signal for accurate ignition timing and rapid startup.
With its adjustable sensor mount, the 24xLink ensures precise alignment between the reluctor and sensor, guaranteeing a rock-solid signal every time. Installation is simple: replace the Optispark with the sensing unit, fit the hub/reluctor, make one adjustment to center the crank sensor, and you’re done. No timing cover removal required.
