Exclusive 5 YEAR Limited Warranty.Despite the fact that the original drawn steel and molded plastic drive belt pulleys have dramaticallydi\x1ferent visual appearances, they are basically the same in terms of e\x1fective width, diameter and o\x1fset.In other words, plastic pulleys will \x1et on an engine that originally came with steel and visa-versa.We set out a few years ago to develop an alternative to the troublesome plastic pulleys. One thatwould not shred or melt and leave the car stranded on the roadside. One that could withstand brutaldays at the track. One that could replace both the steel and the plastic. What you see here is the realizationof our goals. Lighter than steel, a little heavier than plastic, they wont shred or melt. They will replaceboth the plastic and the steel pulleys equally well. We think they are also quite good looking!NEW NEW NEW512.117.UC Replaces: 512.117.EC Replaces: 512.117.TA Replaces:997.102.118.00 997.102.119.00 997.102.117.00996.102.118.56 996.102.119.58 996.102.117.57(Upper On Console) (Lower On Engine Case) (On Tensioner Lever)v32'
