XAT 3UR Supercharged 7" Pulley for ATi Crank Dampers


Not rated yet

Looking to push 800+ HP out of your 3UR engine? This pulley will make that an easier goal to hit! We custom made these pulleys with a 7 inch diameter to bolt on to our ATI crank pulley (not the factory one) and replace the factory size pulley they are normally made with. Our oversized pulley will help spin your supercharger faster, as boost pressure from a supercharger depends on the speed of the drive pulley and ratio between the crankshaft pulley and the supercharger's pulley.

We offer these a la carte now for anyone that has previously purchased one of our custom ATi crank damper pulleys, and is looking to throw more boost at their engine.

Stronger internals are absolutely required when running this pulley. You do not want to test the limits of your engine if you do not have aftermarket rods and pistons installed. Professional installation and tuning is required.
