Answer me this, because I am puzzled. If Trucker #1 has a 4" suspension lift on his Dodge 1500 series 4x4, with 35" tires and Trucker #2 has a 6" suspension lift on his Dodge 1500 series 4x4 with 35" tires, who has more ground clearence. Think about your answer and then look at your statement above.

Some people like the look of the taller stance with a 6" kit with 35's, and some people like the look of bigger gaps between their tires and the wheel wells. That's fine, it's all about personal taste.
I, however, like the look of a full wheel well. Plus the handling characteristics of the slightly lower center of gravity. It's all about taste - a 6" or 8" suspension lift with 35" tires offers no more ground clearance than a 4" suspension lift with the same 35" tires. It's the tire height alone that dictates ground clearance. Additional lift height (if ample enough) simply allows the use of taller tires.

If you are going to get a 6" lift, the only advantage would be to clear 37" tires where a 4" lift tops out at 35's. However there are two issues to deal with:
1) Pro Comp and Fabtech lifts (and don't get me wrong, they are both good products) do not provide 6" of lift. They are both a tad under 5.5", and NEITHER can clear 37's without trimming. At least Superlift advertises their 5.5 as a 5.5. The only true 6" lift on the market to my knowledge is the Skyjacker and they are the only ones to claim to fit 37's with no other mods.
2) 37" and larger tires are just too damn big for an IFS truck (it doesn't matter what brand truck it is) you will break front end components with just moderate off road use. I have friends who have replaced many front end components just from driving and turning huge meats on pavement.

 

HAHA, good point. Guess people dont think about the actual GEOMETRY and ENGINEERING of the kits, they get caught up in the #'s. A 6" Lift SHOULD get you more room for tire articulation (using 35's) though. I tend to agree those kits are all basically the same especially on OUR trucks (IFS).

I really onlysay thisbecause I too was planning on getting a 6" kit (probably fabtech) until reading more forum reviewslately. Now im definatelyconsidering the Rancho.

 

What is the install process like for the 4" Rancho kit? Is it do-able by someone who has never installed one before? If not...what are your estimates as to what it would cost to have it put in by an automotive shop?

 

i know that the 6in lift for the 06-07 ram 1500 is a true 6in lift. They say on their site that you can clear a 36x12.5.
