What kind of CUMMINS QSX15 fuel injector will you get from Rsolid ?

1. You’ll get it all with; 100% O-ring replacement for proper sealing, a new Actuator Assembly, Spill Valve, To top it off, every nozzle is tested for 100% proper fuel delivery. It just doesn’t get much better than that.

2. Meticulous testing? You got it! This injector goes through a strict reassembling and testing process for fuel delivery, injection pressure, and timing. If you want more power and reduced emissions, this is the way to go.

3.To put things in perspective, you’re getting proper fit and function because strict OE specifications are met.

There’s no doubt you’ll get exceptional quality and consistency. Why? Each injector is completely disassembled, components are cleaned, and lastly this bad boy is checked for wear and breakage. It comes from the reconstruction of China’s top fuel system OEM manufacturing factory, you can’t beat it
