ERR2958 Crankshaft Sprocket – Defender / Discovery / Range Rover V8

Maintain precise timing and restore proper engine synchronization with this Crankshaft Sprocket (Part No. ERR2958) for Land Rover’s 3.9L, 4.0L, and 4.6L V8 engines. This sprocket drives the timing chain from the crankshaft and is essential for accurate valve timing, smooth operation, and long-term engine reliability.

Worn sprocket teeth can cause timing slack, chain noise, ignition timing issues, and poor performance. Replacing the crankshaft sprocket is highly recommended during timing chain service or top-end rebuilds.

Manufactured to OEM specifications, this sprocket ensures perfect fitment and the correct tooth profile for reliable engagement with the timing chain.
