Stanadyne Fuel KIT - RGX 12mm LT2 High Pressure Fuel Pump and 8 LT4 Fuel Injectors
Stanadyne’s RGX Fuel Pump and LT4 Gen 1 Injector kit represents the ultimate race-focused fuel system upgrade for your high-horsepower GM LT engine. 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.
RGX High-Volume Fuel Pump
At 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.
LT4 Gen 1 Direct Injection Injectors
Complementing 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.
