Description

Improve the performance in your vehicle by replacing your factory crank pulley with the COBB Tuning Lightweight Main Pulley. This particular pulley has been fabricated from billet 6061-T6 high-grade aluminum, and it has been anodized blue to provide extra protection against rust and corrosion,

Lightweight crank pulleys reduce rotational mass without affecting the balance of the flat 4 motor. This pulley is almost 4lbs lighter when compared to the factory unit and the result is improved throttle response while maintaining the factory pulley diameter to help with installation.

Sweet pulley

This is the 2nd pulley I've purchased from Cobb, first one for my 04 rs and again for my 2010 Forester XT. Both AT cars, definitely improves throttle response and I've also gained better fuel mpg. This is one of the best performance mods you can do for the money.

great pulley!!!

I first bought this pulley for my 04 RS back in 2005 when Cobb was located in Murray Utah. Enjoyed so much I bought another for my 2010 Forester XT. Noticed an improvement in gas mileage, but the reason you buy something like is for the performance and it does increase throttle response. It also adds a little bling to the engine bay.

Absolutely the best company I've ever had the pleasure to work with! I issues with my first pulley, the keyway wasn't wide enough. They sent a replacement for it within a week and the replacement worked perfect . Couldn't ask for better service

It may be blue, but it's the bomb!!

Aaah, the wisdom of Jesse Pinkman, but actually I love the blue color. I bought this ice blue Cobb crank pulley about a year ago for my '02 Subaru Impreza 2.5 rs, it fit great and its running smooth like the day it was first installed. I had it installed with the blue gates belts and an agency power alternator pulley and they provided a noticeable difference in concert with each other. Even just this Cobb pulley is worth it by itself and looks very cobberific!! I've had many compliments from my friends that say, I've got something going on under the hood. My car continues to run, rev and accelerates smooth as silk thanks to this great pulley. Thanks RSD!!

  • Q: Harmonic Balancer?  Mother_Bell 2 years ago

    Answer

    Working at an automotive shop I was advised not to get this because it would cause more vibrations because apparently this is the harmonic balancer, can anyone clarify if this will cause any damage due to vibrations?


    • A: The only time that we have seen issues is with this piece being paired with a lightweight flywheel.


      guest57853c642a8d25b5018c44a7 2 years ago
    • A: The boxer engine is naturally balanced as is the straight 6 and V-12 engine configurations.

  • Q: Light flywheel + this pulley  Doug35506 3 years ago

    Answer

    On my 02 wrx i currently have a 12lb flywheel. Would this pulley plus the flywheel cause a CEL?


    • A: We cannot confirm whether or not this will cause a CEL, but it is a common issue when someone has both a lightweight flywheel and lighter crank pulley that they run into throwing a CEL.

    • A: what is a CEL? How does it damage your car? I have this pulley and need a new flywheel


      Dmansuba 3 years ago
    • A: Check engine light. Certain CEL's will throw the car into limp mode and prevent normal operation. Lightweight pulleys with a lightweight flywheel have been known to throw CEL's. Normal weight flywheels are not reported as having issues.
