On the \u003cstrong\u003eVortec 6.0L LQ4\u003c\/strong\u003e, this slack results in accessory belt whip, glazed ribbing, chirping, and underdrive slipping at the alternator—especially during peak electrical loads on models equipped with the factory 130 Amp charging system. Furthermore, OEM composite idler pulleys dry out their internal grease, leading to high-frequency bearing chatter and eventual seizure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty accessory drive overhaul kit replaces degraded OEM hardware with an application-specific spring-damped tensioner assembly (\u003cstrong\u003e38158\u003c\/strong\u003e) paired with a precision-spun steel idler pulley (\u003cstrong\u003e38001\u003c\/strong\u003e).
