    Great affordable way to lift your truck
    The kit is everything it says it is however the istallation in my case wasnt easy. Had the truck been newer with less rust on bolts and such it would have been better. The torsion bar keys were terrible getting off but thats to be expected on a 10 year old truck. I got 285/70-17 firestone destination mts under my truck with this lift. And it looks great. Great affordable lift.
