STANADYNE GEN 5 GM LT V8 GX SERIES FUEL PUMP
Within the GX Series, the RGX “Race Grade Extreme” pump was engineered for professional motorsports applications that operate at or above the cutting-edge 8-millimeter stroke threshold, while the SGX “Street Grade Extreme” pumps were developed for high-output daily-driven vehicles. With both options, tuners can now match a fuel pump’s capability with specific power goals and use cases.
With carefully modeled internal flow paths, finite element-validated structures, and an innovative nested return spring system designed to maintain cam follower contact at high stroke and speed, the GX Series is engineered to provide full-flow output at high RPM with minimal drop-off for today’s most aggressive performance builds.
Unlike modified OE service pumps, Stanadyne’s GX Series of fuel pumps were purpose-built to safely deliver extreme flow and pressure while withstanding the substantial loads and stresses seen when modern engine platforms produce significantly more power than stock.
Additionally, Stanadyne’s (formerly known as Goliath) large-plunger GDI architecture has already demonstrated that moving from base pump families to the Goliath-spec 12-millimeter plunger and high-lift design can unlock approximately 50 percent more volume than the SP1250 and roughly 22 percent more than the SP1550 at comparable pressures.
The GX pumps debuted as part of Stanadyne’s broader performance system strategy to pair high-flow, high-pressure GDI pumps with equally capable injectors to create a fully matched fuel delivery solution for tuners who demand both maximum power and long-term durability.
