If you're building an LS swap or replacing a worn flywheel on one of these trucks, this flat-step, 6-bolt flywheel is a direct fit for the Gen III\/IV small block.\u003c\/p\u003e\n\n\u003ch2\u003eWhy This Flywheel Is a Common LS Swap Part\u003c\/h2\u003e\n\u003cp\u003eGM's Gen III and Gen IV small block V8 engines, commonly known as the LS family, were installed across an enormous range of Chevrolet and GMC trucks and SUVs during this era, all sharing the same bolt pattern and flywheel specification regardless of which specific model or displacement the engine came out of. Because this 168-tooth, flat-step flywheel matches the crank bolt pattern used across the 4.8L, 5.3L, and 6.0L versions of this engine family, it's become a popular choice not just for factory replacement on these trucks but for LS swap projects where the engine is being installed into a different vehicle entirely, which is why it's frequently sold and searched under both use cases.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCross-referenced to OE number 12561680\u003c\/li\u003e\n\u003cli\u003e168-tooth ring gear for manual transmission applications\u003c\/li\u003e\n\u003cli\u003eFlat-step design with 6 crank bolt holes\u003c\/li\u003e\n\u003cli\u003eMade from steel for durability under repeated clutch engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Flywheel\u003c\/li\u003e\n\u003cli\u003eTransmission type: Manual\u003c\/li\u003e\n\u003cli\u003eRing gear count: 168 teeth\u003c\/li\u003e\n\u003cli\u003eFlywheel step: Flat (0.0\")\u003c\/li\u003e\n\u003cli\u003eCrank bolt holes: 6\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel\u003c\/li\u003e\n\u003cli\u003eCondition: New\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFits the 2001-2007 Chevrolet Silverado 1500, 1500HD, 2500, 2500HD, 3500, and 3500HD, the 2001-2007 Chevrolet Suburban, and the 2001-2007 GMC Sierra 1500, 1500HD, 2500, 2500HD, 3500, and 3500HD and GMC Yukon, all with the 4.8L, 5.3L, or 6.0L Vortec V8. Because this flywheel is also commonly used in engine swap applications outside of these factory vehicles, confirming your specific engine's bolt pattern and flywheel step against the OE number above is worth doing before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eSigns Your Flywheel Needs Replacing\u003c\/h2\u003e\n\u003cp\u003eA worn or damaged flywheel on these trucks typically shows up as a grinding or chattering noise when engaging the clutch, a clutch pedal that feels different than it used to, or visible scoring and hot spots on the flywheel's friction surface when the transmission is out for a clutch job. Because the flywheel's ring gear is also what the starter motor engages to crank the engine, worn or chipped teeth can also cause a grinding noise specifically when starting the truck.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Replace the Flywheel During a Clutch Job\u003c\/h2\u003e\n\u003cp\u003eSince accessing the flywheel requires removing the transmission, most shops and experienced owners replace or resurface the flywheel any time the clutch is already apart, rather than reusing a flywheel that's shown any sign of wear and risking a second transmission removal soon after. A fresh flywheel also gives a new clutch disc a true, unworn surface to grip, which helps the new clutch engage smoothly rather than compensating for an already-worn flywheel face.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eInstalling this flywheel means removing the transmission to access the bell housing, unbolting the old flywheel from the crankshaft, and torquing the new flywheel down with the six crank bolts in the correct sequence and to the manufacturer's specification. Because a flywheel is intentionally imbalanced to work with a specific crankshaft, using new bolts rather than reusing worn ones is generally recommended given the stress this connection sees during clutch engagement.\u003c\/p\u003e\n\n\u003ch2\u003eOrdering Information\u003c\/h2\u003e\n\u003cp\u003eThis flywheel is in stock and ships ready to install.
