This Belt Wrap Kit was designed to eliminate belt slip on the SRT-6 as well as SLK32 & C32 engines. In order to increase "belt wrap" around the supercharger pulley (and reduce Belt-slip/Boost loss which becomes more of an issue with smaller/higher boost SC pulleys), the kit reroutes the belt below a new idler next the SuperCharger pulley. All pulleys are Billet Aluminum and have a hard-black-anodize coating on all belt surfaces. The kit also includes a bracket that improves the original Mercedes/AMG design by mounting 2 of the pulleys in "double shear"; it also includes an underdrive pulley for the alternator (slowing it down by approx 15%). The picture attached with the numbered pulleys and bracket (and hardware) shows the most popular configuration (for sets-ups utilizing an undersized SC pulley and OE sized crank pulley). It shows the 5 pulleys and bracket (and hardware) that come in this version of the kit.. Versions of the belt-wrap kit intended for owners running other combinations of crank pulleys (with or without SC pulley change) are also available.
