Holley started with their cutting-edge Gen 3 Ultra Carburetor and then crafted a cost-effective version suitable for high horsepower engines. That's why the Sportsman Dominator features the Gen 3 main body, which is 5/16 taller than the previous generation. The added height accommodates larger air entries for smoother flow and improved throttle response.  

The carburetor features an all-aluminum construction with tunable billet metering blocks and throttle position sensor mounting points. Using the knurled curb idle screws, you can easily adjust idle by hand rather than using tools.
