nope, it's just a plain ole spindle lift but with an option for 2 shocks. you have to crank your t-bars to get up to 6"
Most XXX-in lifts all look the same with the exception that some of them push the wheels out a little like the Fabtech spindles, which lift about 3".
The only real difference is what wheels and tires you run with it, what type of bed you have and what look you prefer. Recently my mom hit my bed and I might be getting a new one, so I've been considering the "looks" I can achieve.
Zach (zabeard) has a really good looking truck. In this picture he has 15x10 MT Classic II rims with 35x1250R15 MT/Rs and a Stepside(??) bed. I used this picture because Zach has 7" of lift (4" superlift /3" BL)
Here is an FX4 with 15x8 wheels and 33x1250 tires and a flareside bed and the RCD lift kit.
See the difference??
