As the LSX type engine becomes more and more popular amongst the street rod/dragstrip crowd the desire to put on a roots blower is greater than ever. RBS carries these billet steel LS crank hubs that give the racer a solid starting point for attaching their roots blower application to the crankshaft.

Hub has the industry standard 2.00" pulley register, uses six .375" bolts on a 2.782" bolt circle for the blower pulley and measures 2.385" from crank gear surface to blower pulley mounting surface. Crank hub is double keyed with one .250" keyway and one .187" keyway a hundred eighty degrees a part to insure the crank hub stays where it needs to on the crankshaft.

Seal diameter on the hub is 2.00" designed for the RCD LS gear drive. RCD crank hub will not seal on a stock LS timing cover.

The hub can be run with no degree ring or RBS can supply a degree ring at additional cost if the customer desires. Crank hub is for internal balance engine and is black oxide finish. Degree ring part number is #2300-0031 if buyer chooses to purchase.
