Unlike modified OE components, this bundled kit features purpose-built hardware engineered from the ground up to deliver the extreme flow, pressure, and durability demanded by top-tier builders, tuners, and race teams. Together, they provide the foundation to safely unlock the next level of forced induction or naturally aspirated performance.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"2\" style=\"text-align: center;\"\u003eRGX High-Volume Fuel Pump\u003c\/h3\u003e\n\u003cp data-path-to-node=\"2\" style=\"text-align: center;\"\u003eAt the heart of the system is the dyno-proven RGX pump, utilizing Stanadyne's advanced Goliath large-plunger (12mm) architecture and high-lift design. Engineered to support 800 to 1,400+ horsepower builds, it delivers 50% more volume than SP1250 pumps and 22% more than SP1550 pumps. The internal pressure relief valve acts as a fail-safe against over-pressurization, while the redesigned GX lower assembly and upgraded spring system ensure absolute stability at high loads and engine speeds up to 8,000 RPM.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"3\" style=\"text-align: center;\"\u003eLT4 Gen 1 Direct Injection Injectors\u003c\/h3\u003e\n\u003cp data-path-to-node=\"3\" style=\"text-align: center;\"\u003eComplementing the RGX pump, the all-new LT4 Gen 1 injectors deliver extreme fuel flow without sacrificing drivability. Manufactured with precision laser-drilled nozzles rather than modifying OEM units, these injectors provide massive flow increases while maintaining the exact OE spray pattern and targeting. The result is uncompromising power potential with OE-quality idle and seamless calibration.\u003c\/p\u003e\n\u003ch4 style=\"text-align: center;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0895\/3082\/7039\/files\/Stanadyne_RGX_Pump_Preload_Guide.pdf?v=1785856637\" rel=\"noopener\" target=\"_blank\"\u003eInstallation instructions can be found by clicking here.\u003c\/a\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h4\u003e","brand":"Stanadyne","offers":[{"title":"Default Title","offer_id":52954654671135,"sku":"06728-611661","price":4811.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0895\/3082\/7039\/files\/Image-_0Stanadyne-RGX-pump.jpg?v=1785849621","url":"https:\/\/paragonperf.com\/products\/stanadyne-fuel-kit-rgx-12mm-lt2-high-pressure-fuel-pump-and-8-fuel-injectors","provider":"Paragon Performance","version":"1.0","type":"link"}
