Our newest S-Drive Serpentine Pulley kits. Our Mopar kits come with a new aluminum water pump housing and all of the components necessary to install the kit. Our Mopar S-Drives are the cleanest looking systems on the market and we utilize a single spring loaded tensioner to keep the serpentine belt properly tensioned at all times; there is need for multiple idler pulleys to clutter up the assembly. The kits come standard with a Mopar OEM look, 165 amp, one wire alternator with internal cooling fan. The S-Drive must be used in conjunction with a thin crank vibration damper with dimensions of Mopar Performance number P3830183 or equivalent (distance from the face of the timing cover mounting surface on the block to the pulley mount surface on the face of the damper measures 2.144”. Spacers are available to accommodate dampers that are shorter).
