Edelbrock 7821 Performer-Link Adjustable True-Roller Timing Chain Set

The Edelbrock 7821 Performer-Link timing chain set is engineered for use with Edelbrock or stock camshafts, delivering reliable performance for street and mild performance applications. This true-roller timing chain features a solid-bushing design that creates a genuine bearing surface rolling with the sprockets, effectively eliminating chain stretch and ensuring precise valve timing over the life of the engine.

Premium Construction:

• Cam sprocket manufactured from high-strength cast iron with 35,000 psi tensile strength
• Crank sprocket machined from billet SAE-1144 steel and induction heat treated for maximum durability
• Solid-bushing roller chain design provides true bearing surface contact
• Three keyway setting points allow accurate timing adjustment for early or late-model engines
• Engineered for reliable operation up to 6,500 rpm

Installation Guidelines:

• Never hammer directly on chain or sprockets to avoid cracking hardened components
• Use a protective sleeve for installations requiring hammering, or carefully alternate blows with a brass drift punch
• Verify clearance between timing chain and block, as well as between chain and front cover
• Ensure cam and crank sprockets are precisely aligned to prevent premature chain failure
• Do not stretch chain with a screwdriver during installation

This timing set provides an excellent balance of performance and reliability for stock replacement and mild performance builds, with precision-engineered components designed to maintain accurate cam timing throughout the operating range.
