            Great product

            Great product for the price! Might as well put better axles in it while doing this hardware to give u room.

            They're bolts

            Not much to say. They're bolts. Harder than the ones that came with the diff bushings. Bought these because of fear of snapping the others while launching my whippled mt82 car on drag radials. The front bolts are a total pain to install with the allen head. Other than that its pretty easy. Did the middle ones while i had my half shafts out during the install which made those incredibly easy. Could easily be done in under an hour but I did these with half shafts, cb005 and a couple other things so it took me an afternoon to install.
