Cloyes 9-3100A-10 Hex-A-Just True Roller Timing Chain Set for Small Block Chevy

Cloyes Gear 9-3100A-10 Hex-A-Just Timing Chain & Gear Set, For Chevy Small Block

Will not fit factory roller camshaft applications. Has a reduced center distance of -0.010 in. With Cloyes Hex-A-Just timing sets, infinitely adjustable cam timing is as simple as turning an Allen wrench. Consisting of SAE 1144 billet steel cam and crank sprockets and a true roller timing chain, these timing sets use a special hex-head bushing installed on your cam's dowel pin. This bushing lines up with degree marks on the cam sprocket. You can adjust timing in fractions of a degree (as much as +/-6 degrees) by loosening the cam bolts and turning the bushing with an Allen wrench. Cloyes Hex-A-Just timing sets install under your stock timing cover and can be used in align-bored blocks. Order the model designed for your vehicle and engine application.
