The Lokar Serpentine Pulley Kit (F‑Body/Truck, AC & PS, Black Finish) is a complete accessory‑drive solution for LS engines using the truck belt line combined with an early F‑Body water pump. This all‑inclusive system drives the alternator, power steering pump, and A/C compressor using a single 6‑rib serpentine belt and a spring‑loaded tensioner for reliable belt control.
