Lift Spacer Comparison/Differences

[Luciendar21]

I'm looking to put a lift spacer in the front of my 2000 Limited. The previous owner had put something unusual in for struts to add lift and fit 285/75R16s, but I put in OEM struts to correct ride softness and wobbling and now I've un-lifted the front.

I'm trying to understand the difference between Daystar kits KT09103BK and KT09106BK. Can anyone help clarify which kit I should get to level the front of the 4Runner with the back?

I've also been advised to go with the Daystar kits because they are poly vs billet aluminum spacers that have steel studs due to the corrosion that will occur where metal meets metal.

I am not really considering springs/struts because I just put in new struts and shocks at all 4 corners.

I answered my own question. The documentation on Amazon is rather poor, as is the organization of Daystar's site, but I was able to glean that:

KT09106BK is a 2.5 in spacer lift kit for both front and rear.
KT09103BK is a 2.5 in spacer lift kit (leveling kit) for front only.

I am still interested to hear people's opinions regarding poly vs billet lift spacers, but in my scenario I will be going with KT09103BK from Daystar.
