My car has been vibrating like crazy and realized the harmonic balancer, front U joint and front yoke are bad. My question is will the stock parts work fine or are there aftermarket parts that would work better? I just dont want to order the wrong parts and have them not fit. Also any mustang parts website that you could let me know about would be much appreciated. So I can order these parts. Thanks

 

stock will be fine if you don't race hardcore

 

As mjr said stock will be fine, but if you're going new, don't bother with stock, for a little bit more money, you can get stronger and better aftermarket stuff. Just check out summits site, they have a rediculous amount of balancers, look into pioneer stuff, same as powerbond, my pioneer balancer for my 408 came in a pioneer box but says powerbond on the balancer. Powerbond makes REALLY nice stuff.

 

for the money my professional products one has worked well on my 347
