So I've replaced most things with OEM Mopar parts except for a few gaskets, which i went with Fel-Pro on because I've only read good things about them. I'd typically go mopar for most vital things but the parts are so expensive that I'm looking for a place to get quality aftermarket parts for things like the harmonic balancer and idle tensioner pulley, etc. I've read mixed to bad things about moog, crown auto, and mostly bad things about...Dorman? I believe is the last one I'm thinking of. I'd really appreciate the advice I'm sorry if I didn't see this covered somewhere in a sticky.

 

Seems to be hit or miss with no brand being exceptional. I settle for Omix-ADA (motor mounts), Doorman, Crown (bump stops), Moog (coil springs), Detroit Axle ( control arms).
i replaced the tension pulley with the following link to unknown brand. Direct fit and functioning well so far.

 

In my opinion, try rockauto.com In over 50 orders in 8 years, I've never had a problem or wrong part. One defective part by the manufacturer which they sent me a new one overnight at no cost. Each part you look up has options for manufacturers, your choice entirely. They even started carrying Mopar parts.
