Don't gamble with your injectors just to hold rail pressure!

Solid race plugs might seem like a cheap solution to lock down your rail, but they create catastrophic pressure spikes when you let off the throttle rapidly—spikes that can destroy the internals of your expensive fuel injectors. This Upgraded 240 MPa (34,810 psi) Pressure Relief Valve gives your custom-tuned 2007.5-2018 6.7L Cummins or LLY/LBZ/LMM Duramax the elevated rail pressure capability it needs while retaining essential pressure relief to keep your injectors alive.

This is a direct drop-in replacement for your factory pressure relief valve or aftermarket race plug with no modifications required.

NOTE: A 240 MPa valve is recommended for the vast majority of street trucks. For competition-oriented builds, consider our 280 MPa Pressure Relief Valve.
