If you've ever looked at the OEM Subaru crank pulley and thought, "This thing's a bit of a brick," you're not alone. It's heavy, it can fail without warning, and let's be honest—it's not winning any beauty contests. So, we decided enough was enough. We wanted something that would lighten the load without compromising safety or reliability. Enter our Lightweight Crank Pulley.
We went all out on this one. Crafted from CNC machined 6061 T6 Aluminum, our pulley shaves off a solid 3.5 lbs compared to the stock version. That means quicker revs and a more responsive engine. Plus, it's built to last, so you won't have to worry about it giving up on you halfway through a spirited drive.
Installation? Super simple. We’ve marked it with a timing mark and designed a perfect cut keyway, so you can get it on without any fuss. And don’t worry about misfires or engine hiccups; we’ve optimized the weight to keep everything running smoothly.
At GrimmSpeed, we don’t just throw stuff out there and call it a day. Our innovation game is strong, and this pulley is no exception. We even whipped up the only aftermarket pulley installation and removal tool that works with both OEM and our lightweight pulley. And if you’re looking to install a stretch belt, we’ve got the only aftermarket kit that fits all 2008+ Subaru models. Talk about covering your bases!
We’ve put a lot of thought into balancing performance and design here. You can expect nothing less than that from us.
So if you're ready to ditch that heavy stock pulley and make your engine feel a bit more alive, this is your ticket. Trust us, you won't regret it.
