ARP Stainless Turbo Studs, Nuts, & Washers for Steed Speed Cat C15 & Cat C15 Acert Exhaust Manifolds
These ARP stainless turbo studs, nuts, and washers are your go-to for Cat C15 & Cat C15 Acert Steed Speed manifolds. But, a quick heads-up: Steed Speed has rolled out a few different turbo flange styles over the years, so double-check your fitment. The side of the stud that threads into the exhaust manifold flange is 3/8” coarse thread, while the side that holds the turbo is 3/8” fine thread. This set isn’t a match for the older through-bolt design manifolds or the newer M10x1.5 studded/threaded versions. Happy wrenching!
