Built for Power Designed for Competition

If you’re pushing your 2004.5 to 2005 Duramax-powered Silverado or Sierra to its limits, the Industrial 0986435504-R3 40% Over Injector is a crucial upgrade to support that extra power. This injector is built specifically for race and sled pull applications where fueling demands go far beyond stock capability. Flowing 31 liters per minute, it delivers 40 percent more fuel than a factory unit, giving your engine the volume it needs to support aggressive tuning, higher boost levels, and serious performance on the track or pull line. It’s a go-to choice for competitors who want fuel delivery that keeps up with high-output builds.

Sold Individually Engineered for Reliability

This injector is sold as a single unit, so if you're building a full set, you'll need to order eight. Each one is precision-built to handle the heat and stress that comes with heavy fueling and prolonged high-load operation. A refundable core charge applies, provided your returned core is in rebuildable condition. Whether you're dialing in a race tune or preparing for your next competition, these injectors give you the confidence to push harder without holding back. This is the kind of part you count on when second place isn't good enough and durability matters as much as performance.
