Features & Product Details

RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed. 

 

This is the GrimmSpeed Lightweight Crankshaft Pulley. This pulley has been designed to be a lightweight direct replacement of the OEM crank pulley to decrease the overall rotational mass. This is ideal for factory 4-cylinder boxer engine designs that have a shorter crankshaft length, and it will increase the engine revs while improving the engine response. Additionally, these lightweight crank pulleys are available in a variety of anodized finishes to improve the overall engine bay aesthetics. 

 

 

 

DETAILS:

  • Anodized red finish with white GimmSpeed logo
  • CNC machined from 6061-T6 aluminum construction
  • Weighs 3.5lbs lighter than the OEM crank pulley
  • Designed with a timing mark and a perfect cut keyway
  • Decreases rotational mass while creating faster engine revs
  • Improves the throttle response
  • Factory fit for a clean installation
  • Optimum weight to avoid misfire CEL's or hesitation
  • Designed with OEM timing marks for timing verification

    Installed this on a 2006 Subaru Impreza 2.5I Wagon, easy enough install, even without the special tool. This thing is SIGNIFICANTLY lighter than the stock one and I was able to immediately feel the difference in acceleration: It's not an insane amount of improvement, but noticeable and worth every penny.

    This part is well built obviously i mean its aluminum and probably made with cnc. This part did remove the staggering when off buck to on throttle. I don't know if this is the cause of my car revving faster or the gear oil change I did with red line 75-90w ns . I mean I was running a liter of sync to mesh. All in all great product and do a dam gear oil change.

    Can definitely feel a difference in reaching higher rpms quicker! Also a little difference in acceleration, enough to notice anyway! Have one in each of my cars now!

    First off this crank pulley looks awesome! But the real reason I wanted this was to help let the car rev up quicker, and it does just that. The car revs noticeably quicker than stock. For my 2006 STI this didn't not require a tune. No CEL or anything. The price is reasonable for the gains you get. 5 stars all the way!

    QUESTIONS & ANSWERS

    • Q: Grimspeed pulley belt install tools  Robert Paz5 years ago

      Do I need to buy the stretch belt kit and the grimspeed pulley install tool to install the pulley?
      • 0 of 0 people found the following answer helpful

        A:  The stretch belt kit and the pulley install tool will make this install much easier but they are not required.

    • Q: grimm speed pulley   daveymcfarland122117 years ago

      do you think it will effect anything negatively if i installed this on my 02 impreza 2.5ts that also already has a 12lb flywheel? i have one off of my other car and i want to install it if i will just get better response but i dont want to hurt anything cause i just did all new gaskets and timing to this engine two days ago and put in a stage 3 clutc with light weight flywheel
      • 0 of 0 people found the following answer helpful

        A:  Installing both a lightweight pulley and flywheel will not hurt the vehicle, but sometimes a check engine light can come up from the crank being too light and the crank sensor not being able to read. Typically we recommend sticking with either a lightweight flywheel or pulley, but not both.

    • Q: crank pulley bolt   hella flush is hella stupid8 years ago

      I see you guys just put the crank bolt in and torqued it on the install vid. The service manual says to put oil on the cap and the threads of the bolt, then torque it down. It mentions two stages of torque and a tolerance of 45 degrees for the bolt. Why is this procedure so complicated in the fsm, and is it necessary to follow these steps with the lightweight pulley?
      • 0 of 0 people found the following answer helpful

        A:  We recommend following Grimmspeed's instruction manual which is found below. They do not mention two stages of torquing or oiling the cap. http://www.grimmspeed.com/content/install_guides/SubaruCrankPulley.pdf

    • Q: Harmonics?  MrFreeze8 years ago

      How do these pulleys effect the harmonics of the motor?
      • 2 of 2 people found the following answer helpful

        A:  The stock crank pulley is not a harmonic balancer and lightweight Subaru crank pulleys do not have any negative effects on engine harmonics.

    • Q: Belt install  nwWRXdriver8 years ago

      I ordeded one of these from the grimmspeed website, I was wondering if I should buy a new Gates belt as well? my 2012 WRX has 32k miles on it.
      • 0 of 0 people found the following answer helpful

        A:  It is strongly recommended to replace the accessory belts due to the low cost and having to remove them while installing this pulley anyway.
