looking to lift...spindle lift kit?

I was looking to lift my 04 taco. After doing research it seems that they spindle lift kit will be the best fit. I was wondering if anybody had any advice about, and good vendors who sell them.

 

If you want to maintain a factory ride quality and lift the truck a decent amount the spindle lift kit is an option. I buy them from headstrong offroad, they are the people. I buy the 4" kit.

 

I was looking to change the suspension so it would add some height and for a little off-roading. How much does a decent spindle kit usually go for?

That's the link for the kit.

 

What is the difference between the Maxtrac and the Camburg lift spindles? Why do I see most people going with Camburg even though they are almost double the cost?
