Tap into hidden horsepower with the FSWERKS crank underdrive pulley (UDP). Our kit includes our 6061 aluminum lightweight crank underdrive pulley and a new serpentine belt. The FSWERKS crank pulley underdrives your accessories by 23%. This, in turn, decreases the drag on the engine, unleashing power that you never knew you had. And since the FSWERKS (7 ounces) crank underdrive pulley is lighter than OEM (3 lbs. 4 ounces) crank pulley, you'll benefit from the weight reduction of rotating mass; resulting in a more responsive engine. FSWERKS crank underdrive pulley is supplied in a red anodized finish.

NOTE: Only fits vehicles equipped with Air Conditioning. Requires trimming the lower timing belt plastic cover for installation.

Improves power, throttle response appreciably esp. at low rpm

Crank underdrive pulley

Nice product. The car feels a bit snappier. The pulley does sit closer to the motor than the factory one, which made it so the plastic casing by the timing belt had to be snipped so the belt wouldn't rub but aside from no other issues car runs great with it on.

Super easy installation and good quality as well. Push it hard everyday and it's been 5000 miles no issue at all. Great product

Response is there!!!

When I installed the kit I saw and felt an improvement in throttle response. I am a SCCA member and this is kit is a must have if you want a faster off the line car.

I felt the difference

Love how this comes with a new belt. I changed my timing belt at the same time and figured a small upgrade would also be nice. I can feel the car revs more freely and it seems to have added a small bit of pickup.
