Rock-Solid LS Timing: Heavy-Duty Gen IV 1-Bolt 4X Timing Chain Set
Are you building a high-performance street machine, preparing your truck for heavy towing, or dealing with persistent P0016 or P0336 crankshaft/camshaft correlation codes in your GM Gen IV V8? Over time, even the legendary LS-series engines can develop annoying timing chain slack, leading to retarded valve timing, erratic idle, and a loss of top-end power. Restore crisp throttle response and rock-solid reliability to your internal rotating assembly with this Heavy-Duty Timing Chain Set. Precision-engineered for non-VVT configurations, this kit eliminates slop and keeps your valve events perfectly synchronized.
A high-performance engine demands a valvetrain system built from premium materials. This heavy-duty kit features a high-strength alloy steel timing chain designed to resist elongation and whipping under high-RPM stress. At the core of this set is a precision-machined 1-bolt design camshaft sprocket, complete with an integrated 4X reluctor trigger wheel to send flawless positioning signals to your engine control module (ECM). Rounded out with a matching crankshaft sprocket and a durable timing chain tensioner/dampener guide with fresh mounting bolts, this kit ensures a quiet, stable drive and long-lasting durability within the front timing cover.
(⚠️ CRITICAL FITMENT NOTE: This timing chain set is designed STRICTLY for Gen IV LS and Vortec V8 engines requiring a 1-Bolt Camshaft Gear paired with a 4X Reluctor Wheel ONLY. It does NOT fit older 3-bolt camshaft profiles, nor is it compatible with engines utilizing Variable Valve Timing (VVT). Please carefully inspect your camshaft core and verify your engine block specifications before purchasing.)
Engineered to upgrade your valvetrain durability beyond standard factory specs. This premium heavy-duty kit flawlessly fits an extensive lineup of 2007-2015 GM vehicles, including the Chevrolet Corvette, Camaro LS3, Silverado, Tahoe, and Express. It is equally compatible with GMC Sierra, Yukon, and Canyon models, as well as high-performance applications like the Cadillac CTS-V (6.2L LSA), Pontiac G8, and Hummer H3. Rebuild your V8's timing system the right way with BTSCAR's premium internal components and drive with total confidence.
