I was considering buying the ARK Lightweight Crank Pulley but I wanted to see if anyone has it and what they thought. I'm kinda concerned about the balance and if it causes any shaking.

wanted a under drive set but hate the Blue color .



its going on a beta2

 

I have used many different underdrive pulleys on a few differnt vehicles and have not noticed any extra shaking or medium term wear to engine parts.

 

I have the full pulley set from ark(crank/ps/wp), been on for 3 years?... with a fidanza flywheel



Have been loving it every minute



I'm sure you read stories about u/d pulleys on internally balanced engines (no harmonic). Although some truth to it, on a DD/anything that isn't high revs the whole time its running, is fine.



So on a F1 or GT car yeah probably a bad idea, on your DD tiburon...go for it

 

Cool thanks,, can I get a full set that's not blue cuz that's all I can find

 

100k + on my beta with an unorthodox udp, nothing exploded (yet)

 

Pretty sure ark is the only one offering a "kit" and im pretty sure they only do blue



OBX i believe offers them in red or silver?
