What to know before buying

Fitment is claimed for 2023–2026 and 2011–2022 6.7L Powerstroke models, but the listing separately calls the older range “Old Models.” It also says 2011–2016 vehicles with sensors may require clearing the fault code after installation. Confirm compatibility and the sensor procedure for your exact truck. The listed 0.1 x 0.1 x 0.1-inch dimensions are unusual for an assembly, so verify them before using them for installation planning.

There is only a single aggregate rating and no written customer feedback. That is too little evidence to establish reliability, fitment or installation experience. Buyers should base the decision on verified compatibility for their truck rather than the rating alone.
