This has been discussed countless times on here. With MANY mixed review's. I've had them for two years now and they work awesome for my 500. Lotsa people dont like the roller bearings because of the chance of the rocker spittin one out. But I think it depends on what your gna use them for?? I dont put any REAL miles on my car so theyre fine for me. A lil street/Strip is fine. BUT, most folks on here think for a daily driver stamp steel are fine. Theyre nice though!!!!!
