On this LB7 Duramax diesel engine, we used our GripEdge G-FORS Deep Socket Extractor. Its straight-cut, non-tapered design gives you true bi-directional control, allowing you to tighten and loosen to break seized fasteners free. Tomorrow, we’re releasing our MX32DS Master 1/4" & 3/8" Drive Deep Socket Extractor Set, featuring both Metric and SAE sizes for maximum coverage of different rounded bolts or exhaust manifold studs sizes you run into! #mechanictools #exhaustmanifold #enginerepair #handt
