No used or reconditioned wear parts are ever used. - **Thoroughly Leak Tested:** Every engine is subjected to multiple pressure decay tests on all coolant and oil passageways to verify seal integrity and prevent leaks. - **Dynamic SIM-Tested:** Before shipping, each engine is cold-motored to check cylinder compression, oil pressure, and oil flow for reliable performance from the moment of installation. ### Our Remanufacturing Process Our comprehensive remanufacturing process begins with a complete teardown and meticulous visual inspection of the core. Blocks and cast iron heads are magnafluxed to detect any cracks. Key components like the block, heads, and crankshaft undergo precision CNC machining to restore them to exact OEM specifications. Every internal wear component—including all pistons, rings, bearings, valves, and seals—is replaced with 100% new parts. After reassembly, the engine is subjected to a battery of tests, including pressure decay testing to eliminate any possibility of leaks and a final dynamic SIM test to confirm compression, oil pressure, and circulation before it leaves our facility. ### Product Fitment #### **Fitment Summary** - **2002-2004 Cadillac Escalade** (5.3L V8) - **2002-2004 Chevrolet Avalanche 1500** (5.3L V8) - **1999-2004 Chevrolet Silverado 1500 & 2500** (5.3L V8) - **2000-2004 Chevrolet Suburban 1500 & Tahoe** (5.3L V8) - **2003-2004 Chevrolet Express & GMC Savana 1500 / 2500** (5.3L V8) - **1999-2004 GMC Sierra 1500 & 2500** (5.3L V8) - **2000-2004 GMC Yukon & Yukon XL 1500** (5.3L V8) * * * #### **Fitment Detail** **Year****Make & Model****Engine Code****Engine Displacement****VIN**2002-2004Cadillac EscaladeLM75.3L / 325 CIDT, Z2002-2004Chevrolet Avalanche 1500LM75.3L / 325 CIDT, Z2003-2004Chevrolet Express 1500 / 2500LM75.3L / 325 CIDT, Z1999-2004Chevrolet Silverado 1500LM75.3L / 325 CIDT, Z1999-2000Chevrolet Silverado 2500LM75.3L / 325 CIDT, Z2000-2004Chevrolet Suburban 1500LM75.3L / 325 CIDT, Z2000-2004Chevrolet TahoeLM75.3L / 325 CIDT, Z2003-2004GMC Savana 1500 / 2500LM75.3L / 325 CIDT, Z1999-2004GMC Sierra 1500LM75.3L / 325 CIDT, Z1999-2000GMC Sierra 2500LM75.3L / 325 CIDT, Z2000-2004GMC Yukon / Yukon XL 1500LM75.3L / 325 CIDT, Z **Have a question about fitment or condition?
