Crankshaft Sockets; Chevrolet Big Block w/1.61 in. ID with 3/16 in. Keyway;
COMP Cams crankshaft sockets are the perfect addition to your engine-building toolbox. They accept 1/2 in. drive ratchets for versatility and easy engine rotation. They're precision-machined for an accurate fit over the crank snout, and their knurled retaining nut threads-on to sandwich a degree wheel in place. The nut can be loosened, while on the crank snout, so that the wheel can be turned independently of the engine when finding top dead center.
COMP Cams manufactures truly superior hydraulic and solid flat tappet, hyd and mechanical roller, and overhead camshafts for everything from OE replacement to full race, designed and manufactured using cutting-edge technology and the finest engineering in the industry. Whether your engine is naturally aspirated, or you run nitrous, or a supercharger or turbo, our cams make more horsepower than any other. Looking for that ultimate hard-hitting muscle car idle? Check out our aggressive new Thumpr Cams. Match our camshafts up with our competition-grade lifters, valve springs, timing sets, and other supporting components, and you'll experience the ultimate in race-winning reliability!
