Hopping Hydro Question

Hey every, iam looking to do a lowerider impala kit or maybe a nice lowrider truck kit. Now i found some things from hoppin hydros, but am a little confused about them. I was wondering if ppl that have worked with them can help me out.
What exactly is the difference between these:

and these:

What is the difference between the hydraulic kits and the chasis kits? i cant quite seem to figure it out. Both of them are used to make the car "dance" but i dunno what the diff is between the two?

The "Chassis" is ready to go (no assembly), and the "Kit" needs assembly. My guess is they both do the same thing, its up to you if you want to save money and build it yourself, or build it to your specifications. Thats my take on it...if im wrong someone please correct me.

Yeah...It looks like the first link is pre-assembled chassis and the second is DIY.

ahhhh ok thats what i thought at first wasnt oo sure, ok thanks guys, another question, does any1 know of any good impala models? iam talking like the older, lower rider type ones. I was looking at some of the ERTL ones, oh dear lord do they ever suck lol.

The Revell/Monogram Lowrider 2n1 kits are decent. If you have intermediate detail abilities the kits can be awesome.
