When installing UR lite weight pulleys you see significant performance advantages. The first advantage is the reduction in rotational mass which is weight the engine has to overcome every time you hit the gas. The reduction in rotational mass means your engine spools up faster for better acceleration. The second advantage is under driving which is turning the accessories at a lower speed so they don’t waste engine power. We tailor the amount of under drive for each engine to maximize the power without hurting accessory efficiency. These advantages also mean better gas mileage for you.
