These starter bolts include a knurled section near the threads that indexes into the block, preventing lateral movement that can lead to starter misalignment, starter damage, or even cracked engine blocks. 269 Motorsports supplies them as a matched pair so you replace both long fasteners at once for reliable fit and performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these starter bolts prevent starter and flywheel damage?\u003c\/h3\u003e\n\u003cp\u003eThe knurling on each bolt seats into the starter bore in the engine block and resists rotational and lateral movement. That positive fit keeps the starter gear properly meshed with the flywheel and reduces stress on both parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled locating surface locks bolt position in the block.\u003c\/li\u003e\n  \u003cli\u003eMaintains consistent starter-to-flywheel engagement.\u003c\/li\u003e\n  \u003cli\u003eReduces risk of starter wobble and flywheel wear.\u003c\/li\u003e\n  \u003cli\u003ePrevents starter-induced block cracking from movement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich LS engines and vehicles will these bolts work with?\u003c\/h3\u003e\n\u003cp\u003eThese bolts are made for LS-family GM V8 engines that use two long starter bolts instead of one long plus one short or different pattern.
