My 2500 would be a great example for you.
I had a tradesman truck, I had HUGE plans for it. It looked like nothing at first, even my wife was like.... why did you buy that? (1st picture)
Then while talking to a few friends, got word of a good discount on wheels and tires. But was only good for that weekend! CRAP!! I want to run 35" tires, I probably could with a stock 2500. Went to Discount to get them - nope, wouldn't do it on the truck unless it was leveled. Damn it.
Went out to Craigslist - got me a 2.5" Rough Country Spacer with shock extensions. My buddy and I installed that kit in 30 mins. Maybe even a tad bit less than that believe it or not! (we've done so many of them, that we're pros when it comes to these trucks).
Next morning go and get the wheels and tires! (2nd picture)
I didn't want to run the spacers for too long. The ride suffered a little bit. It sure was stiff, even going from 80psi tires to 65psi tires.
Long story short, had the spacers for a year or so. I finally had some extra cash and I called up Don (Thuren) and said - hey, ship me a set of springs and some overlander shocks. I put those in and wow.. what a difference that was. It was so much softer and the bumps where just not jarring nor teeth rattling. It rode so smooth that my buddy went out that next week, got rid of his spacers and did a front and rear kit from Thuren. Overland shocks as well.. and he LOVED the ride. If you go the Fox - or King shocks I am sure it's 5 and 10 times better than the overland shocks... but Overland shocks are pretty decent in price.
So yeah.. you can feel a HUGE difference between factory and leveled - and then from leveled to Thuren Leveled.
I also had a few trucks with the Carli springs.. and Thuren is way softer.
