Restore Ultimate V8 Power: Master Timing Chain & Sprocket Overhaul Kit for Nissan/Infiniti 5.6L VK56VD & 5.0L VK50VE
Are you experiencing a severe cold-start chain rattle, sluggish acceleration, or timing-related fault codes in your heavy-duty Nissan or Infiniti V8? The powerful 5.6L VK56VD and 5.0L VK50VE 32-Valve DOHC engines are built for extreme hauling, towing, and luxury performance, but high mileage inevitably leads to timing chain stretch and worn sprockets. Left unaddressed, this slack can cause catastrophic valvetrain failure. Restore factory-level precision and bulletproof reliability to your Titan, Armada, or QX80 with this Ultimate Master Timing Chain Overhaul Kit. Engineered strictly for the advanced VK-series V8 engines, this comprehensive package provides every essential heavy-duty component required for a complete front-end rebuild.
What makes this master overhaul package truly exceptional is the inclusion of a complete 8-piece gear and sprocket set. Reusing old, worn sprockets with new chains often leads to premature chain wear and repeated failures. This premium kit maximizes your engine teardown value by providing brand-new intake, exhaust, idler, and crankshaft sprockets, alongside high-strength primary and secondary timing chains.
Key Features & Included Components:
8-Piece Sprocket Set Included: Features 2x Intake Camshaft Sprockets, 2x Exhaust Camshaft Sprockets, 2x Idler Sprockets, and 2x Crankshaft Sprockets (Upper & Lower) for perfectly synchronized, factory-fresh gear engagement.
Complete Chain Set: Includes 2x heavy-duty primary timing chains and 2x secondary chains engineered to resist stretching under heavy towing and high-torque loads.
Complete Hardware: Comes with left and right primary tensioners, fixed guide rails, and curved tensioner arms for a bulletproof and noise-free front-end service.
(⚠️ CRITICAL FITMENT NOTE: This master timing kit is engineered STRICTLY for the 5.6L VK56VD and 5.0L VK50VE DOHC V8 engines. It DOES NOT fit the older generation VK56DE engines found in early Titans and Armadas, nor does it fit any other platforms. Please carefully verify your exact engine code, vehicle year, and OE part numbers before purchasing to ensure proper fitment.)
Engineered to meet or exceed strict OEM specifications for long-lasting, noise-free performance under extreme loads. This comprehensive upgrade kit flawlessly fits a massive lineup of Nissan and Infiniti flagship platforms, including the 2010-2023 Nissan Titan / Titan XD (5.6L), 2010-2022 Armada, 2014-2022 Infiniti QX80, 2009-2013 QX56, and the Infiniti Q70/M56 sedans. Rebuild your heavy-duty V8 the right way with BTSCAR's premium replacement components and hit the road with absolute confidence.
