Product Overview
This combination is for a performance build that also needs fresh valve timing control. Replacing the chain while installing the cam avoids asking a stretched, high-hour chain to hold accurate timing with a stronger profile—but guides, tensioner, sprocket, rockers, journals, springs, and oil supply still determine whether the build survives.
The Stage 2 cam increases valve lift and duration while the chain keeps the cam synchronized to the crankshaft. Confirm chain pitch and link count, cam number, decompression setup, piston-to-valve clearance, spring capacity, and every model-year timing detail.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Why install a timing chain with the new cam? A: A stretched chain can retard or vary cam timing. Replacing a worn chain helps the new profile operate where intended.
Q: Is this a bolt-in repair for a poorly running engine? A: No. It is a performance package for a healthy, measured engine with compatible fuel, exhaust, and valvetrain setup.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
