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 black 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.

Nice product
MattSax07WRXTR 2 years ago
I could tell a slight improvement in acceleration. It seemed to help get my 07WRX through the turbo lag zone faster. Plus, the original wheel was so heavy I could use it as a boat anchor.

noticeable difference

great product, pretty amazing how much lighter this crank pulley is than the stock brick. Noticeable difference on the cars launching ability/ throttle response. No issues with CEL's, great product, highly recommended.

Surprising difference
Dan_the_man432120040 3 years ago
Put this in on my 2007 Impreza 2.5i and am seriously impressed with the difference. Didn't go into it expecting a ton of change but was very surprised with how much acceleration gain I can feel. I wish I had run some numbers to give a straight value on the gains but I would highly recommend this to anyone, its a cheap upgrade that you can actually notice.

Super lightweight, Easy-to-Install

Installed this on my 2009 LGT, easy install and noticeable improvement in throttle response. Doesn't hurt that it's a great looking, well-made piece either. Throw some Gates belts on top and call it a day!

Had a difficult time finding a shop that would install this for me (I don't own the necessary tools for the job). Once installed, I can tell that the car has a more lively feel when accelerating. Well worth the purchase. I had the 2 external belts changed at the same time.

  • Q: Belt upgrade  Eyopia13 2 years ago

    Answer

    I am looking to purchase this for my 05 WRX and would want to upgrade my belts at the same time with the gates blue racing belts. Can you tell me which part numbers I would need to upgrade all belts while performing this install? Thanks!

  • Q: Install Question?  blackmagickei16229 3 years ago

    Answer

    Does this require a tune? I'm sure one is recommended but is it a requirement or can I drive it right after install?

  • Q: Requirements?  blackmagickei16229 3 years ago

    Answer

    Does this REQUIRE a tune? I know for most parts, a tune is recommended, and for others, a tune is required, before driving your vehicle. So is this part one of the required ones? I wanted to put it on myself since I have the tool, but wondered if I should beforehand, and how drivable is it without a tune? I plan on driving it out of state for a dyno tune in Oregon, but if it isn't recommended to make a distant drive without a tune, I won't put it on.


    • A: There is no tuning required for a pulley Also it depends on your car, but if you have a 1993-2007, there is no need for any special tools.

  • Q: sorry one more question  TheBirdWRX 5 years ago

    Answer

    Would this pulley ever mess with the warranty just a little worried because the car is so new ?


    • A: No part can void your warranty, but you will have to speak with your local dealership to see if they are friendly towards aftermarket modifications. Generally the worst case is that they deny you warranty work at that particular time, but always best to check before you install anything. Thanks.
