Why this part
Generic hardware stretches, corrodes, and rounds off. ARP's manufacturing tolerances mean consistent thread engagement and a head that holds its shape across multiple removals. For caliper brackets and ancillary brake hardware, the stainless 300 series hits the right balance of corrosion resistance and strength without the cost of overkill chromoly fasteners.
