ENGINE LOCKING KIT | BMW N51/52/53/54 (SK1158)

Product description

This engine timing tool kit is designed for setting camshaft, valve, and VANOS timing on BMW’s new generation inline-6 engines equipped with valvetronic and double VANOS systems. It is suitable for use on engines with aluminum/magnesium blocks found in 2006 and newer model year vehicles. The kit is used during timing chain or VANOS service, cylinder head work, or other engine repairs that require precise alignment of timing components.

The tools in this kit allow technicians to accurately lock and align the camshafts and VANOS units, ensuring correct timing during assembly or maintenance. The components are constructed from black-oxide plated steel and anodized aluminum, with steel alignment pins for durability and precise fitment.
