Make the Broken Bolt Repair Fast…ProMAXX Fast!
With a focus on book time saved, return on investment, and increased productivity, experienced technicians and mechanically adept individuals who follow the provided instructions can use these kits to make the fractured stud repair in approximately 15 minutes per bolt*. A professional-grade drive ratchet is required to make the repair. The guide plate bolts to the top or bottom of the cylinder head, providing unrivaled accuracy and precision.
*Repair times may vary depending on the location of the broken bolt, whether a previous extraction attempt such as welding has occurred, if a previous repair resulted in a broken extractor or bit and the number of broken bolts. In repairs with multiple broken bolts, ProMAXX Tool recommends purchasing additional drill bits. In the case of repairs involving broken bits or extractors, a ProMAXX Tool Broken Extractor Repair Kit is recommended.
How does the GM 8.1L & 8.8L PSI Broken Bolt Repair Kit work?
Like all ProMAXX Tool broken bolt repair kits, the GM 8.1L & 8.8L PSI Engine Exhaust Manifold Broken Bolt Stud Repair Kit stands out for its exclusive screw-in bushings and proprietary mating angles, which ensure perfect alignment of the ProPlate jig with the cylinder head. The ProPlate can be bolted in any position with included precision fasteners, providing unparalleled repeatable and predictable results.
This level of accuracy and precision sets the kit apart from other products on the market, which rely on inexpensive clamps or loose slip-fit bushings. The accuracy allows the user to drill dead-center on the bolt hole.
For previous repair attempts or botched repairs, the ProKit’s larger plate holes provide the use of a thread repair kit that includes bushings, bits, and black-oxide coated threaded inserts to restore the cylinder head to factory condition.
Premium Machine-Shop Grade Drill Bit Tooling Included
ProMAXX Tool’s USA-made machine-shop-grade tooling bits are ground at 135° cutting angle (lip) with a split point. Flat ground bits cut slower and are long lasting but less accurate and will walk while drilling.
Split point ground bits will stay on center to reduce walking because they have four cutting edges and distribute loads better. They work well on curved shapes and alloy and stainless steels because it creates smaller chips to minimize clogging holes and breaking bits.
To prevent drill bit breakage, closely follow the instructions in the Exhaust Manifold Repair Kit User Guide.
