Designed for 2003-2004 5.9L Cummins engines machined .020 inch over, this piston kit offers a combination of durability and performance focused enhancements that go beyond a standard replacement. The thermal barrier coating helps control combustion heat, while the low friction anti scuff skirt coating is engineered to reduce friction and promote smoother piston travel over the life of the engine. Chamfered piston tops also help reduce cylinder wall scuffing, giving your rebuild added protection during heavy towing and demanding driving conditions. Every matched piston set includes rings, wrist pins, and clips, making it easier to complete your engine build with confidence and fewer additional parts to source. Furthermore, the reduced compression height makes these pistons well suited for applications running elevated boost and increased cylinder pressure. If you want your .020 inch oversize Cummins rebuild to be prepared for years of dependable performance, this Industrial Injection piston kit is built to deliver. \u003c\/p\u003e \n\n\u003ch4\u003e Precision Designed For Demanding Oversize Applications \u003c\/h4\u003e \n\n\u003cp\u003eThe Industrial Injection 244121 ISB X-Series Coated and Chamfered Piston Kit is engineered specifically for 2003-2004 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins 24 valve ISB engine that has been machined for a .020 inch oversize bore. Manufactured as a matched piston set, these pistons install as direct drop in replacements while incorporating several upgrades intended for performance oriented diesel engine builds. Each piston features a thermal barrier coating on the crown that helps manage combustion temperatures, while the low friction anti scuff skirt coating is designed to reduce piston skirt wear against the cylinder wall. Additionally, the chamfered piston tops help reduce cylinder wall scuffing during demanding operating conditions, improving long term durability. The .015 inch reduced compression height supports applications operating with elevated boost levels, increased cylinder pressure, and heavy towing demands. Every kit includes matching piston rings, wrist pins, and retaining clips to simplify installation and maintain proper component compatibility throughout the rebuild. For builders seeking premium oversize pistons that combine proven fitment with enhanced thermal protection and durability, this X-Series piston kit delivers the performance and reliability expected from Industrial Injection. \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2003, 2004 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\u003eDesigned for 2003-2004 5.9L Cummins 24V ISB engines.\u003c\/li\u003e \u003cli\u003eThis kit uses .020 inch oversize pistons.\u003c\/li\u003e \u003cli\u003eThe engine block must be machined for .020 inch pistons.\u003c\/li\u003e \u003cli\u003eVerify cylinder bore size before ordering.\u003c\/li\u003e \u003cli\u003eCompression height is reduced by .015 inch.\u003c\/li\u003e \u003cli\u003eConfirm compression height compatibility before installation.\u003c\/li\u003e \u003cli\u003eCheck piston to valve clearance on modified engines.\u003c\/li\u003e \u003cli\u003eRecommended for elevated boost and cylinder pressure.\u003c\/li\u003e \u003cli\u003eSuitable for heavy towing and performance builds.\u003c\/li\u003e \u003cli\u003eIncludes pistons rings wrist pins and clips.\u003c\/li\u003e \u003cli\u003eConsult your engine builder for modified applications.\u003c\/li\u003e \u003cli\u003eSupersedes previous PDM-3672CC.020 part number.\u003c\/li\u003e \u003c\/ul\u003e  ","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":54384554115356,"sku":"IIS244121","price":1648.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/244117_14.webp?v=1785530613","url":"https:\/\/www.alligatorperformance.com\/products\/industrial-244121-coated-chamfered-isb-x-series-piston-kit-020-2003-2004-dodge-ram-2500-3500-4wd-5-9l-cummins-24v","provider":"Alligator Performance","version":"1.0","type":"link"}
