| This double-roller timing-chain set is a perfect complement to our high-performance camshafts and engine packages. It offers greatly enhanced strength and accuracy compared with the stock piece, and even allows for timing adjustments (advance or retard) of up to 8 degrees. The set contains an adjustable, nine-keyway nitrated crankshaft sprocket, a double-row chain, a nitrated camshaft sprocket, two oil-pump-spacer plates, detailed instructions, and all necessary installation hardware.
NOTES: The cam sprocket in this kit is for a single bolt core camshaft, it will not work on three bolt core camshafts.
NOTES: This timing chain fits ZL415 and ZL427 engines with single bolt cam gear. |
