Question:

What is the difference between SAS, IFS, and solid suspensions?

Ok so ive been trying to do some research on what kind of suspension would be good for me but i cant seem to understand what the difference of these are. I have a 2004 Tacoma. I want a lift that will give me more clearance, it is 2wd so it isnt gonna go offroad very much. Can anyone help me make a decision to which would be my best choice as well as explain the difference between these different type of suspensions?

Answer:

And WHY do you NEED more clearance with a 2wd truck that you won't take off road? Stop throwing your money away and just drive the stupid truck the way it came from the factory.
Independent suspension allows each wheel on an axle to move without affecting the opposite one. This gives better ride quality at the expense of complexity and reduced articulation. Solid beam or live axle suspension has a single axle with a wheel at each end. It is cheap, and very strong, however the movement of one wheel is transmitted to the other wheel compromising ride on the road. Don't know what SAS is, some kind of airbag set up I'm guessing. These suspension systems are fitted by the factory and it's unlikely a previous owner would have swapped it out for something completely different. Too expensive. If you want a lift kit, get one to suit your vehicle. The Taco has a IFS I think but your dealer will give you a kit to suit it.
