Adjustable camshaft gear pulley for BMW M20 engines

Made from a oem sproket, therefore no problems with sproket tooth profile, like with some aftermarket sprokets that are damaging timing belt.

Robust and reliable double plate design, with bolts and self locking nuts for adjusmet plate locking, therefore no risk for threads damage with frequent timing adjustmens.

Bolts are locked with high strengh thread locker, that realeases only if preheated, therefore no risk for backing-off.

Wide range of adjustment (+-10 (20deg) camshaft degree or +-20 (40deg) crankshaft degree).

Very useful with modified engines, for example for necessary timing adjustmens of 2.7 2.8 stroker builds with decked engine block to achieve correct timing, also useful for oem and aftermarket cam adjustmens for desired performance.

Made for 12v 6cylinder older type BMW engines from e30 e34 - M20 M20b20 M20b25.
