Yes and no. The fan itself bolts up the same distance from the water pump shaft flange. The fan bolts up to the rear of the aluminum clutch and only the thicker aluminum clutch protrudes further forward. The flan blades are still the same distance from the radiator with the standard, heavy duty, or severe duty clutches.
