Hey guys, I have a 2011 Srt8 Challenger with the Hennessey HPE 650 package. I think one of my axles is starting to go bad. Looking to just go ahead and replace both since the car has 150k miles. I have priced out the mopar ones at around $500 ea and ones from Napa (new) at $130 ea. I have thought about even going with aftermarket performance axles, but I can't justify $1k+ ea for an axle for street use. Have any of you used the napa ones and if so how are they compared to the oem ones? Feel free to recommend other axles that are worth checking out. Thanks
