The Industrial Injection X-Series Fly Cut Coated and Chamfered .040 Piston Kit is engineered for 1998.5-2002 5.9L Cummins 24V engines that have been machined for a .040 inch overbore, giving performance minded builders the strength and clearance they need. The .100 inch fly cut valve reliefs provide additional piston to valve clearance, making this kit an excellent choice for engines equipped with higher lift camshafts and upgraded valvetrain components. Additionally, the thermal barrier coating helps manage piston temperatures under heavy loads, while the low friction anti scuff skirt coating promotes smoother operation and reduced wear over time. Chamfered piston tops further improve durability by helping reduce cylinder wall scuffing during demanding engine operation. Every kit includes matched pistons, rings, wrist pins, and clips, allowing you to assemble your engine with components designed to work together from the start. Whether your truck spends its time on the street, at the track, or pulling heavy loads, this piston kit is built to support the performance your Cummins is capable of delivering \u003c\/p\u003e \n\n\u003ch4\u003e Precision Machined For Demanding Engine Combinations \u003c\/h4\u003e \n\n\u003cp\u003e The Industrial Injection X-Series Fly Cut Coated and Chamfered .040 Piston Kit is designed for 1998.5-2002 5.9L Cummins 24V 6BT engines that require a .040 inch oversize piston after machining. Each matched piston is manufactured to provide consistent dimensions across the complete set, helping maintain balanced engine operation and dependable performance. Furthermore, the thermal barrier coated piston crowns help reduce heat transfer into the piston, while the anti scuff skirt coating minimizes friction between the piston and cylinder wall throughout the engine's operating range. Chamfered piston tops help reduce cylinder wall scuffing, and the .015 inch reduced compression height provides additional clearance for higher cylinder pressures and elevated boost applications. Integrated .100 inch fly cut valve reliefs create the piston to valve clearance needed for higher lift camshafts and more aggressive valvetrain configurations. The kit includes matching rings, wrist pins, and retaining clips to simplify assembly and ensure compatibility between components. Before installation, verify that your engine has been machined for a .040 inch overbore and confirm all compression height and clearance requirements to ensure this piston kit matches your specific build. \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 1998.5, 1999, 2000, 2001, 2002 Dodge RAM 2500\/3500 4WD 5.9L Cummins 24V \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e \u003c\/p\u003e\u003cul\u003e \u003cli\u003eFits 1998.5-2002 5.9L Cummins 24V 6BT engines.\u003c\/li\u003e \u003cli\u003eThis listing is for the .040 inch oversize version.\u003c\/li\u003e \u003cli\u003eRequires an engine block machined .040 inch oversize.\u003c\/li\u003e \u003cli\u003eVerify final cylinder bore size before ordering.\u003c\/li\u003e \u003cli\u003eFeatures .100 inch fly cut valve reliefs.\u003c\/li\u003e \u003cli\u003eConfirm piston to valve clearance before assembly.\u003c\/li\u003e \u003cli\u003eUses a .015 inch reduced compression height.\u003c\/li\u003e \u003cli\u003eVerify compatibility with your camshaft and valvetrain.\u003c\/li\u003e \u003cli\u003eConsult your engine builder for modified applications.\u003c\/li\u003e \u003cli\u003eIncludes matched pistons, rings, wrist pins, and clips.\u003c\/li\u003e \u003c\/ul\u003e  ","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":54409489121564,"sku":"IIS243122","price":1551.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/243116_12.webp?v=1786035015","url":"https:\/\/www.alligatorperformance.com\/products\/industrial-243122-fly-cut-coated-chamfered-6bt-x-series-piston-kit-040-1998-5-2002-dodge-ram-2500-3500-4wd-5-9l-cummins-24v","provider":"Alligator Performance","version":"1.0","type":"link"}
