Product Description
Michigan Motorsports LS Single-Bolt 58X Timing Chain Set with Tensioner
Heavy-Duty Gen III/IV LS Timing Set | Single-Bolt Cam Gear for 58X LS3, L99, LS4, LS9, LSA & Compatible 2007-2014 LS Engines
Refresh the timing system in your compatible 58X LS engine with the Michigan Motorsports LS Single-Bolt Timing Chain Set. Designed for Gen III/IV LS engine combinations using a single-bolt camshaft sprocket configuration, this complete timing set includes a single-bolt timing cam gear, crank sprocket, tensioner kit, and upgraded heavy-duty timing chain. The high-performance chain is manufactured with higher tensile strength to support improved timing accuracy and long-term durability, making this kit a smart upgrade during camshaft swaps, timing service, engine rebuilds, and higher-mileage LS refresh projects.
Key Features & Benefits
- Complete Single-Bolt LS Timing Set: Includes the core timing components needed to service compatible LS engines using a single-bolt camshaft sprocket, helping eliminate the need to source each timing component individually.
- Designed for 58X LS Engine Applications: Built for compatible LS3, L99, LS4, LS9, LSA, and related Gen III/IV LS engine combinations using the listed single-bolt timing configuration and 58X reluctor wheel setup.
- Upgraded Heavy-Duty Timing Chain: The included timing chain is manufactured to a higher tensile strength for greater timing accuracy and longevity in stock replacement, street-performance, and modified LS engine builds.
- Tensioner Kit Included: Includes a timing chain tensioner, retainer, and bolt to provide a complete timing chain service solution for compatible factory-style tensioner applications.
- Ideal During Camshaft Installation: A practical timing system upgrade when performing a camshaft installation, front cover service, timing chain replacement, engine rebuild, or other LS modifications where the timing assembly is already accessible.
