Description
This GFB Pulley Kit comes with the crank, alternator and power steering pulleys as well as the belts needed for install. Having large heavy pulleys spinning takes away power that is better spent moving the car. This kit takes care of that by replacing the crank pulley with a smaller lighter version. On your average underdrive pulley kit your accessories all spin slower. GFB takes care of that issue by providing smaller lighter pulleys for the power steering and alternator so they will maintain their stock functionality.

Awesome Pulley set!
Jcool 1 year ago
Bought this for my 06 STi. Install was a breeze, taking a little over half an hour. Fit and finish was great, and the Gates micro-V belts work great. Pulleys are significantly lighter than stock, and has no CEL problem at all. Revs are quicker, and hitting shift are much easier due to increases rev control. I was amazed at how easily this kit went on to the car, and how smooth and driveable it was after install.

I installed this kit on my 05 STI and it made a noticeable difference in throttle response and makes the car more eager to rev. Install went very smoothly in less than a half hour and the quality is great. I've been running this with a Competition Clutch lightweight flywheel and have not had any issues with a check engine light or anything else. I'm also running a small battery and the alternator works as well as it did before. 5 stars for fit, finish and functionality.

My Review..
wrxgucci 2 years ago
Good: Much Lighter than stock Look much better than stock Bad: Power Steering Pulley Stripped the inside of the pulley after 7 months I have been trying to get a replacement for almost a month from the manufacturer. I think this is due to them being in Australia but the customer support rep that was dealing with this claim is out of the office for two weeks over the holidays.

07 STI

Installed on my 07 STI. Install was a pain for lack of correct tools and limited space. Weight savings from stock pulleys is pretty significant. No problems running with them so far. Response wise, things seem to get going a little quicker than they did before the install. Overall I'm glad I got these.

  • Q: These + Flywheel  Lark_thelandshark 11 months ago

    Answer

    I've heard that it's unadvisable to run lightweight pulleys and a lightweight flywheel. Input?


    • A: These pulleys are lighter in weight than stock. With that said, there is a possibility coupled with a light enough flywheel that you may see a check engine light.

  • Q: Will this combo work   DC_09 1 year ago

    Answer

    I have a Perrin crank pulley would the power steering and alternator pulley work with the crank pulley I have. Would I need a new belt?


    • A: It is recommended that you run the crank pulley included in this kit. New belts are recommended, but existing belts can be reused depending on condition.

  • Q: SG9 STi  Miran 2 years ago

    Answer

    Will this kit fit the 2004 Forester sti?


    • A: This should however, Subaru used differently power steering pulleys and we have no way of knowing which pulley you have. If your pulley uses a hex bolt, this kit will not work. If it uses a regular nut, this kit should work for you.
