I used the HCR Sport Line A-Arms and Trailing Arms in my wifes car, did a 64" to 72" conversion. I think they are great for the recreational rider. If you are into big air, pay the price for parts designed for that kind of abuse, like the more expensive Sport Line, or CT, Geiser, LoneStar etc.... 800 miles later, very satisfied. One note, the early versions of the rear trailing arms did have some issues with the sway bar mounts. HCR contacted me and is sending me a new set on their dime, even tho I have not had any issues. Kudo's to them.
I do note, based on my conversations with HCR, these are not made "in house". But, like I said, zero issues so far.
