I tried to install the U-box dead pedal from Amazon previously and it didn't fit properly. I never did get the Amazon one installed. I also didn't like the fit and finish.
The Quadratec pedal was a very quick install. It's way nicer also. However, it was on backorder for 4-5 months.
I’m happy with the lift setup. It’s still fairly new for me to really comment. However, the dealer picked up my truck for warranty service on the back window. He stated the truck drove just like his stock Mojave, which is amazing considering the 37s.
