When You Need More Fuel To Win More Races

If you’re building your Duramax for serious competition, then you already know stock injectors just won’t cut it. The Industrial Injection 100% Over Injector is built for those chasing podium finishes, not just dyno numbers. Designed specifically for the 2004.5–2005 LLY Duramax, this injector brings the extra fuel your engine craves when it’s under extreme load during race or sled pull events. With a 50 LPM flow rate, you’re looking at a huge increase in fueling potential that pairs perfectly with aggressive tuning and airflow upgrades. It’s sold individually, so you can replace just one or buy a full set of eight depending on your build plan. Keep in mind, these are not street-oriented parts, they’re crafted for competitive environments where every ounce of performance counts. When you’re up against the clock or the weight of the sled, having injectors that can keep up with your power demands makes all the difference. This is the kind of upgrade that turns a strong build into a championship contender.

Precision Fueling For High Output Duramax Builds

The Industrial Injection 0986435504-R6 injector delivers a true 100% over fuel output, engineered to meet the high demands of race-built Duramax LLY engines. With a 50 liter-per-minute flow rating, it ensures consistent fuel delivery even under the extreme pressure and heat of competitive driving. This injector is built with performance in mind, using proven components and machining tolerances that support modified fuel systems and high-horsepower configurations. It fits the 2004.5–2005 Silverado and Sierra 2500HD/3500HD models equipped with the 6.6L LLY Duramax, offering a direct performance replacement for factory injectors. While the injector comes individually packaged, full sets require the purchase of eight units. A core charge is applied, but customers can receive a refund when rebuildable cores are returned. These injectors are commonly used in high-stress sled pulling and drag race builds where precision and durability are critical. If your setup demands more from your fueling system, this injector is built to deliver without compromise.
