Audi MKI TT 225HP ECS Performance Underdrive Pulley Kit
Our three-piece pulley kit combines weight savings with an overall underdrive pulley ratio to take back the power that is usually lost to inertia and accessory loads.
Available in black, blue, or red, these pulley kits come with a smaller diameter crank pulley, larger diameter power steering pulley, and stock diameter alternator pulley. This balanced combination reduces parasitic power losses associated with accessory loads and the high moment of inertia of heavier pulleys.
Our carefully in-house engineered set works perfectly with your stock tensioner and belt to save you money.
