Question:
What model number for a Triflex NEXT and Discovery NEXT for a 2024 Yukon? Which do you recommend?
asked by: Doyle E
Expert Reply:
Hey Doyle, the correct Curt Triflex for your 2024 GMC Yukon is the part # C65YV and for the Discovery # C97YV.
I would definitely recommend the Triflex over the Discovery as it is proportional and the Discovery is time delayed. Proportional means it senses how hard you are applying the vehicle brakes and applies the same braking intensity to the trailer brakes. Time delayed on the other hand means a preset amount of braking pressure ramps up over time.
