The kit facilitates the removal of broken exhaust manifold bolts on Dodge HEMIÂŽ 5.7l and 6.1l engines. Kit works on Chrysler 300C, JeepÂŽ Grand Cherokee, Dodge Durango, Ram pickup trucks, and Dodge Challenger R/T and Charger R/T models. It is the smallest and thinnest available to make the fastest repair. ProMAXX Toolâ??s exclusive screw-in bushings, which incorporate proprietary mating angles, once seated, have the most precise alignment with the cylinder head. Bottom Line: If you canâ??t get the most accurate hole placement, why use a tool at all? Dodge uses super hard titanium studs / bolts, making them impossible to weld and nearly impossible to drill. ProMAXX solved that prob incorporating our premium Platinum Tooling (Drill) Bits that can drill not only Titanium, but Boron, and even Ultra-Strength Steel. ProMAXX kits incorporate splined, slip-nut styled non-deforming extractors that can be utilized both in the clockwise and counter-clockwise direction. This unlocks the broken remnant without pinching it in the cylinder head as in other kits which make your repair nonproductive. Other kits use inexpensive clamps or loose slip-fit bushings. Bolt Alan in any position with our included precision fasteners to provide unparalleled, repeatable, and predictable results. Received a previous repair attempt or botched repair? No Problem. ProMAXX Tools larger plate holes provide the use of a thread repair kit that includes bushings, bits, and superior solid steel inserts, unlike spring-style, to completely restore the cylinder head to factory condition.
