Are you facing a mechanic's worst nightmare with your GM 2.4L Ecotec engine? Whether you are dealing with a spun bearing, catastrophic internal engine failure, or severe oil consumption due to worn piston rings, replacing the entire engine isn't your only option. Designed specifically for 2011-2017 Chevrolet, GMC, and Buick models equipped with the 2.4L Direct Injection (LAF/LUK/LEA) engine, this comprehensive Bottom-End and Cylinder Head Rebuild Kit delivers all the critical internal components needed to bring your engine back from the brink and restore reliable, factory-spec performance.
A proper bottom-end rebuild requires perfectly matched, high-strength rotating assembly components. At the core of this master package is a precision-machined replacement crankshaft, perfectly paired with four new connecting rods and four premium pistons (pre-matched with pins and a complete set of piston rings). To ensure flawlessly smooth rotation, we have included a complete main and rod bearing kit with thrust washers. Moving to the top-end, this kit provides 16 brand-new intake and exhaust valves, 10 fresh cylinder head bolts, and a complete master engine gasket and seal kit (featuring a premium MLS head gasket) to guarantee a tight, leak-free reassembly. As an added value for mechanics and DIYers, a specialized piston ring installer pliers tool is included in the box.
(⚠️ IMPORTANT INSTALLATION NOTE: This master kit focuses strictly on the rotating assembly and cylinder head resealing. It does NOT include timing chain components or an oil pump. Please carefully verify your engine code (LAF, LEA, or LUK) before purchasing to ensure proper fitment for your specific vehicle.)
Engineered to save you thousands compared to a complete engine replacement. This robust kit flawlessly fits popular crossover SUVs and sedans, including the 2011-2017 Chevy Equinox, GMC Terrain, and Buick Regal, as well as compatible Captiva Sport, Malibu, Impala, Orlando, LaCrosse, and Verano models. Rebuild your Ecotec engine the right way with BTSCAR's premium internal components and get your vehicle back on the road with total confidence.
