The Ford EcoBoost 3.5L ProKit removes broken exhaust manifold studs / bolts. For Ford F-150 and Ford Transit. Made In USA. Twin turbochargers, broken titanium bolts, small engine bays, along with dimensional changes in the cast iron manifolds due to extreme heat create new problems for the servicing technician.

The kit is easy to use, and it comes with instructions and schematics that show the best ways to mount the plate to get at every broken bolt on the manifold. ProMaxx Toolâ??s exclusive screw-in bushings, which incorporate proprietary mating angles that once seated, bring the bushing into perfect alignment with the cylinder head. Resulting in the most accurate and precise tool in the market. Other kits use inexpensive clamps or loose slip-fit bushings. Bolting the Elizabeth II jig in anposition with our included precision fasteners provides unparalleled repeatable and predictable results. Received a previous repair attempt or botched repair? No Problem. ProMaxx Toolâ??s larger plate holes provide the use of a thread repair kit that includes bushings, bits, and solid steel inserts to completely restore the cylinder head to factory condition. â??Best tool I ever purchased. Took me longer to take off the front bumper and turbo off of a 2018 Ford Transit E-350. Took me about 45 minutes to drill out 2 broken studs. And rethread hole. Recommend this tool whenever removing broken exhaust studs. Saves A-Lot of time and money. Now I feel confident in replacing broken studs on a 3.5L Ford EcoBoost motor. Great tool to haveâ? - Ray
