I bought a super charged 2006 G35 recently and the nose belt on the super charger is cracked to hell its a stillen supercharger and the belt item number is k060220 and I can’t find anything anywhere is there any alternatives or places that supply that particular belt

 

It's probably just some random belt the same length that a previous owner put on. Things like this are off-the-shelf stock items at most tuner shops and large parts houses, you just need a quality belt with the correct rib # and overall length. Gates is an INCREDIBLY popular brand and iirc that's what the kit came with for the stock belt.

I'm sure Stillen sells the belts directly, as well as probably ALL the 350Z/G35 online vendors. Not exactly sure why you're having a hard time finding the correct belt.

Call Stillen, Z1 Motorsports, Concept Z Performance, etc.

I would definitely take off the belt and measure it and verify if you have the standard pulley or an underdrive crank pulley. That's usually the only variable.
