This Raven Series S-Drive 8 rib serpentine pulley kit replaces a mismatched factory accessory drive on the LS engine with one complete, matched system. CNC-machined billet aluminum brackets and pulleys mount every accessory in the kit and run them on a single 8 rib serpentine belt, so the front of the engine looks clean and finished. It is built for LS engines equipped with variable valve timing.
