Anyone have experience with the 2 piece BDS or Pro Comp leveling kits? How difficult is it to install the preload spacer? I like the idea of the preload spacer to accommodate a heavier tire.

 

Don't think the preload spacer is going to help with a heavier tire, where did that come from a manufacturers website? Going to need a heavy duty spring compressor these truck springs are a little bigger than car springs.

 

I have the Pro Comp kit installed on my 2015 Super Crew FX4. I was going back and forth between the one piece Rough Country, and the two piece Pro Comp. I was sold on the pre-load spacer as a good idea, especially if you plan to add any additional sprung weight (eg. winch bumper) to the front end.

The truck looks awesome now, and no difference that I can't detect in ride quality or handling.
