TrackTech fasteners primarily manufactures diesel performance parts, head studs, and gasket kits. But we are quickly expanding into the automotive parts industry. Some of the most powerful engines in the world are held back by the bolts keeping them together. That's why we took it upon ourselves to develop the strongest studs in class for Ford, Chevy, GMC, Dodge, Honda, Subaru, and other major brands. Our laboratory-tested and professionally lap-tested fasteners and hardware includes head studs, main studs, connecting rod bolts, exhaust manifold bolts, valve train components, as well as fuel lines, HPOP systems, and oil coolers. Whether you're a repair shop looking for a head gasket kit or a truck owner fitting diesel parts in the hunt for more power, our head studs, main studs, and connecting rod bolts will hold your engine together through every power boost.
