08 ford 6.4 half kit
Deltas over 30 going up 6 % grade empty before installing the half kit. A week later after installing half kit, I pulled my car trailer on a 8 hour drive hauling a 79 super cab and never got over 7 degrees difference. My wife and I did the complete install in 5.5 hours. I would absolutely recommend it hands down.
