What is the difference between these two lifts?

Maybe a dumb question but I see the bottom kit has ubolt and the coilovers come pre-assembled. Is that all?

 

One has the coils prebuilt with new bushings and top mount. It also comes with rear Ubolts and axle shims

Preassemble usually $100-150
Ubolts - $50
Shims - $30.

They probably added extra markup because most people dont have the skill or tools to assemble the coils themselves.

 

Do I need the new ubolts with the top one?

 

Yes. U bolts should always be a 1 time use item. If you take them apart, you SHOULD throw them away.

As for length, I needed longer Ubolts for my toytec AAL, the stock ones wouldn't have worked even if I wanted to use them.

Both kits look to use the single Toytec AAL.
