1998 Jeep Wrangler Remanufactured Engines

Remanufactured Engines are fully disassembled; heads, blocks, cranks & cams are machined & wear parts are replaced. Each engine is individually tested after assembly to assure compression, oil pressure and water jacket integrity.

Product Features:

• Each engine we remanufacture is essentially reverse engineered – in part to discover original factory deficiencies. If possible, our seasoned R&D personnel & QC experts make improvements. Why shouldn’t our engine last longer than your first?
• Engines come with installation gasket set & oil pump unless noted otherwise. If we have important installation information it will be included on tags or in the paperwork packaged with your engine.
• Engines are securely packaged in a recyclable container that will also protect your core on the return trip. Our nationwide warehouse network means speedy delivery.
• Each engine is remanufactured with quality OE level components not “white” box generic parts that may or may not satisfy your needs and expectations. When you use the best you get the best results and satisfaction.

ATK High Performance Engines are based on dyno proven combinations built with name brand parts. Most performance engines come in 3 different dress levels and range from 245HP-700HP+ carrying a 2 Year Warranty built by a name you can trust.

Each block is magnafluxed for cracks and checked for any visible damage to the block or threaded holes before being repainted. Five CNC machining centers are programmed to precise specifications that meet or exceed those established by the OEM for each engine block. After the engine block is bored, decked, and chamfered, each cylinder is honed with the specified OEM cross-hatch pattern. All gauging of all cylinder bores for diameter and roundness after final honing operation. Quality audits are performed to ensure that the cylinder meets specifications. All new pistons, rings and bearings are installed in every engine. One block per engine family is laid out and checked for all critical and high impact characteristics as defined in our control plans. These measurements include surface finishes, surface flatness and cylindricity in the cylinder bores. Every head is resurfaced and completely inspected for any visible damage or cracks to the casting or threaded holes. Valve seats are machined, inspected and replaced if necessary. The cam bore is air gauge checked on overhead cam engines and machined if required. All new valves, seals and lifters are used in every head. All plugs and fittings are replaced with new. All head and valve assemblies are quantified for leakage. Each connecting rod is measured against OEM specifications. The piston pin bore and bearing bore are measured with air gauges for proper dimensions. New torque to yield rod bolts and nuts are installed. Crankshafts are machined on a fully automated Ju crank CNC crank grinder. All oil galley holes are chamfered and brushed after machining. Each crank is inspected for cracks, bow and all applicable run-out specs for rod and main journals. Sims Testing – All engines are cold motored and checked and measured for proper torque to turn, cylinder compression, oil flow, oil pressure and any unusual noises. All engine assemblies quantified for oil gallery, gasket, and casting leakage in the oil passageways

Product Features:

• REMANUFACTURING and QUALITY CHECKS – ENGINE BLOCKS: Each block is magnafluxed for cracks and checked for any visible damage to the block or threaded holes before being repainted to the original color.
• CYLINDER HEADS: Every head is resurfaced and completely inspected for any visible damage or cracks to the casting or threaded holes. Any heads that have cracks in the combustion chamber are immediately scrapped, no weld repairs.
• CONNECTING RODS: Each connecting rod is measured against OEM specifications for bend, twist, and center-to-center length before use. The piston pin bore and bearing bore are measured with air gauges for proper dimensions.
• CRANKSHAFTS: Crankshafts are machined on a fully automated CNC crank grinder. This enables consistency and critical tolerances for each journal.
• DYNAMIC ENGINE TESTING: Sims Testing – All engines are cold motored and checked and measured for proper torque to turn, cylinder compression, oil flow, oil pressure as well as monitored for any unusual noises inside the assembly.
• Product might not be available in all states due to local laws.
