The Industrial Injection AFC Spring Kit is built to fix exactly that, giving you smoother throttle response and more control when you’re into the throttle hard. This kit replaces the stock AFC spring with a stiffer one, slowing down the fuel delivery so your turbo has time to spool up before being flooded with fuel. The result is cleaner power, less smoke, and better drivability whether you're daily driving or hauling serious weight. It’s a small upgrade that makes a big difference in how your truck behaves under boost. Instead of feeling like your truck is surging or blowing clouds of smoke too early, you’ll get a much more linear, usable powerband. For anyone looking to tune their 1994-1998 Cummins the right way, this kit is a must-have.\u003c\/p\u003e\n\u003ch4\u003eTuning Fuel Delivery Starts With The Right Spring\u003c\/h4\u003e\n\u003cp\u003eThe 1994-1998 Dodge Ram 12-valve Cummins runs a mechanical P7100 injection pump, and part of its fueling behavior is controlled by the AFC housing. Inside that housing sits a spring that determines how quickly fuel is delivered based on boost pressure. Industrial Injection’s AFC Spring Kit replaces the factory spring with a stiffer one, slowing the fuel ramp to better match turbo spool time. This modification helps reduce pre-boost over fueling, which is one of the biggest causes of excessive smoke, lag, and inefficient combustion. With more controlled fueling, the truck becomes easier to tune and responds more predictably under load. This is especially valuable for trucks running larger injectors or upgraded turbos where fueling needs to be dialed in carefully. The included parts are designed for a direct fit and are built to handle high-boost setups commonly found in performance or towing applications. Whether you're chasing horsepower or just want a cleaner, more efficient setup, this kit sets the foundation for smarter tuning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 1994, 1995, 1996, 1997, 1998 Dodge RAM 2500\/3500 5.9L 12 Valve Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned specifically for 1994–1998 5.9L 12-valve Cummins engines\u003c\/li\u003e\n\u003cli\u003eIntended for trucks with performance modifications or tuning\u003c\/li\u003e\n\u003cli\u003eNot a power-adding part on its own but improves fueling control\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBest results seen when paired with upgraded turbo or injectors\u003c\/li\u003e\n\u003cli\u003eRequires access to and disassembly of the AFC housing\u003c\/li\u003e\n\u003cli\u003eInstallation may require basic diesel mechanical knowledge\u003c\/li\u003e\n\u003cli\u003eComes as a complete kit with necessary components included\u003c\/li\u003e\n\u003cli\u003eRecommended for use in high-boost or towing setups\u003c\/li\u003e\n\u003cli\u003eNot intended for emissions-compliant or stock-only builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Industrial Injection","offers":[{"title":"Default Title","offer_id":53628088254748,"sku":"IIS232708","price":35.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/product_u_n_untitled_7_1800x1800_89e11430-0548-47ca-b87b-d52cb5c3174b.webp?v=1767045868","url":"https:\/\/www.alligatorperformance.com\/products\/industrial-injection-232708-afc-spring-kit-1994-1998-dodge-ram-12-valve-cummins","provider":"Alligator Performance","version":"1.0","type":"link"}
