Coils vs. spacers
I've searched the forum for answers to my lift questions, but what I've found comes up short.

What are the advantages to a suspension lift that replaces the springs over
just the spacers in a budget boost?

Secondly, same question for repalcing shocks as opposed to using the shock

I'm not overly concerned about the difference in costs, just the difference
in performance and functionality.

Factory shocks are going to have a lower load rating (usually) than after market shocks. The big difference between a budget boost and a coil lift comes into play when you start adding after market accessory (winch, bumper, rock rails, etc). All of these things weight down your Jeep. Good, after market springs, are designed to handle this extra load without sagging. Your factory springs, however, are not.

Additionally, a budget boost is a polyurethane puck, and will give you EXACTLY what it advertises. So, if it says that it's a 2.5" lift, then you will get EXACTLY 2.5" of lift. However, if you are looking at a 2.5" coil lift (depending on brand) you can gets upwards of 3" of lift sometimes.

Now, when those factory springs start to sag on your budget boost, you will have even less of a lift than the advertised whereas a coil lift will be unlikely to sag less than it was advertised at.

I hope I made sense of that... in short, springs are better.

As far as shock adapters versus replacement shocks... that depends on what type of shocks you have right now. In general, if you are only looking at a 2" to 2.5" lift, and have a Rubicon with relatively low miles, then you factory shocks are fine for the time being and shock adapters will work just fine.

However, if not all of those things are true, then new shocks of an appropriate length for your lift is advisable.

Thanks u-joint, that helps alot!
I have a 2010 Sahara that according to my build sheet, has gas shocks. I don't know if the length is the same as a Rubicon shock though.
I was looking at a 2.5" lift.

Thanks again.
