There is not currently a kit for the L15B7, so utilizing some ARP hardware, along with our own spacers we have made a kit that will work for ours and others needs.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eARP uses premium grade 8740 alloy that is heat treated to 200,000 p.s.i.

This procedure involves about ten very slight cuts and results in an exceptionally straight part.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eARP studs are thread rolled after heat treat which gives them about 1000% better fatigue strength than studs that are threaded prior to heat treat (a very common industry practice).
