Detailed Application and Design

Melling positions this kit as a performance-grade option with standard, heavy-duty, and performance coverage across its timing chain lineup.

Compatible With Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, and related V8 applications listed in the fitment data, this timing set is also used in Chevrolet Corvette, Pontiac Firebird, and Pontiac GTO applications. The part number 48561T-9 is a direct reference for buyers comparing timing sets for these engine families.

What It Helps Address
