Description

The PERRIN Lightweight Crank Pulley weighs in at just 1.2lbs, which is  about 4 lbs lighter than the OEM crank pulley. Lightweight crank pullies are safe to use on boxer 4 cylinder engines due to the shorter crankshaft length. The reduction in rotational mass results in more horsepower, and a better throttle response. 

This Lightweight Crank Pulley has machined grooves that will work with OEM, as well as aftermarket belts.  The PERRIN crank pulley is machined from 6061T6 billett aluminum, anodized red and laser etched for increased belt life and a precision fit.

Easy install

Easy to throw on in 20 to 30 mins and I actually can feel the engine rev quicker. Also looks great. Inexpensive quick upgrade!

Great upgrade, low cost
Brew04 2 years ago
I'm always on the look out for easy upgrades for reasonable cost. The Perrin lightweight pulley has one of the better weight reduction for its price. Install was straight forward following online videos. Definitely feel better shifting with this install.

Love the extra power.

I'm coming from driving Nissans (300zx Twin Turbo) so I expected the same kind of engine tolerances from Subaru, which is why I wasn't too nervous about putting on a LW pulley. Forums reviews warned against LW pullies but I said screw it. So glad I did. Paired with the Gates racing belts, this is a fantastic pulley. Well balanced and acceleration has improved. My butt dyno says it was a good mod.

'15 WRX cvt & STI review
surfsmurf 3 years ago
In the CVT, there is chopping, meaning in low rpms, the engine almost stalls out which is worrying and uncomfortable to everyone in the car (because everyone feels it). 5k miles w/ it and the gains were noticable, but that doesn't outweigh the discomfort brought on by the engine revs dropping to 200-300 for a second then jumping back up to 650 revs. In the STI, the gains were noticeable but small, I haven't noticed any side effects and I have only had the for mentioned chopping once in the STI after 10k miles.

Easy install. Hardly noticeable change but this pulley is way lighter than stock.

  • Q: whats in the package when purchased?  evade3g88150 2 years ago

    Answer

    I know that the purchase is for the pulley but will a new bolt also come with the pulley?


    • A: Hardware is not included with this Perrin Pulley. You would either reuse or replace your OEM bolt.

  • Q: Tune?  Cbarks13 3 years ago

    Answer

    My question is will this throw a CEL on my dash? I've heard that it would without a tune. I have a v3 AccessPort but I wanted to go ahead and ask if I needed a pro tune or what after installing this?


    • A: You should have no CEL after installation.

  • Q: Possible Thrown CEL?  ShaBorse 3 years ago

    Answer

    Compared to other pulley upon installation, has this product been verified on throwing CEL?


    • A: In most cases, this will not throw a CEL code. In the case that it does, once they are cleared, they should stay off.

  • Q: Install tool  Grat1332 4 years ago

    Answer

    on the perrin website they have an optional tool for the placement of the belt onto the pully. am i going to need to purchase this from them seperatley?


    • A: The stretch belt tool is needed for 2008+ models and the tool part number is GAT 91031. You can type that part number in the search box to view the tool.

  • Q: Installation and Tune  snowbound89 4 years ago

    Answer

    I've been looking around at pulleys and noticed that the Perrin seems to be the lightest weight pulley out there. My question is, how difficult will it be to do yourself. There does not seem to be a good tool like the GS one has. Also with such a decrease in weight will a tune be needed?


    • A: Installing a crank pulley on a Subaru is not very difficult and I would plan on about 1-2 hours for installation time. There is not a pulley tool for this right now, but there are other ways to keep the engine from spinning while loosening and tightening the pulley bolt. Tuning is not required.
