The Industrial Injection X-Series Coated and Chamfered .040 Piston Kit is designed for 2003-2004 5.9L Cummins owners who want more than a basic replacement component. A thermal barrier coating helps manage combustion heat, while the low friction anti scuff skirt coating is engineered to reduce wear and promote smooth operation through countless miles of driving. The chamfered piston tops also help reduce cylinder wall scuffing, making these pistons an excellent choice for trucks that regularly tow, haul, or operate under increased boost. Every matched piston set includes rings, wrist pins, and clips, giving you the core components needed to move your rebuild forward with confidence. Additionally, the reduced compression height makes this kit well suited for more demanding diesel combinations that require greater durability than a standard piston can provide. If your goal is a dependable .040 inch oversize rebuild with proven performance upgrades, this Industrial Injection piston kit is built to deliver lasting results. \u003c\/p\u003e \n\n\u003ch4\u003e Engineered To Support High Load Diesel Applications \u003c\/h4\u003e \n\n\u003cp\u003e The Industrial Injection 244122 ISB X-Series Coated and Chamfered Piston Kit is manufactured 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 .040 inch oversize bore. This matched piston set installs as a direct drop in replacement while incorporating several design enhancements intended for higher demand diesel applications. Each piston features a thermal barrier coating on the crown that helps control combustion temperatures, while the low friction anti scuff skirt coating is designed to reduce friction between the piston and cylinder wall during engine operation. Furthermore, the chamfered piston tops help reduce cylinder wall scuffing, contributing to improved durability under elevated cylinder pressures and sustained heavy loads. The .015 inch reduced compression height makes these pistons well suited for engines operating with increased boost levels and performance oriented tuning. Every kit includes matching piston rings, wrist pins, and retaining clips to simplify installation and ensure proper component compatibility throughout the rebuild. For builders looking to combine a .040 inch oversize engine restoration with proven thermal protection and long term durability, this X-Series piston kit provides the precision 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\n  \u003cli\u003eDesigned for 2003-2004 5.9L Cummins 24V ISB engines.\u003c\/li\u003e\n  \u003cli\u003eThis kit uses .040 inch oversize pistons.\u003c\/li\u003e\n  \u003cli\u003eThe engine block must be machined for .040 inch pistons.\u003c\/li\u003e\n  \u003cli\u003eVerify cylinder bore size before ordering.\u003c\/li\u003e\n  \u003cli\u003eCompression height is reduced by .015 inch.\u003c\/li\u003e\n  \u003cli\u003eConfirm compression height compatibility before installation.\u003c\/li\u003e\n  \u003cli\u003eCheck piston to valve clearance on modified engines.\u003c\/li\u003e\n  \u003cli\u003eRecommended for elevated boost and cylinder pressure.\u003c\/li\u003e\n  \u003cli\u003eSuitable for heavy towing and performance builds.\u003c\/li\u003e\n  \u003cli\u003eIncludes pistons rings wrist pins and clips.\u003c\/li\u003e\n  \u003cli\u003eConsult your engine builder for modified applications.\u003c\/li\u003e\n  \u003cli\u003eSupersedes previous PDM-3672CC.040 part number.\u003c\/li\u003e\n\u003c\/ul\u003e  ","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":54384569221404,"sku":"IIS244122","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-244122-coated-chamfered-isb-x-series-piston-kit-040-2003-2004-dodge-ram-2500-3500-4wd-5-9l-cummins-24v","provider":"Alligator Performance","version":"1.0","type":"link"}
