Do you guys usually replace your original spring isolators when installing a lift, or is it OK to reuse the old ones?

Secondly, wondering if those of you running coil spacers use them along with isolators, or do you just remove the isolators? I've heard you can do either, I guess the isolators contribute to a very small amount of the overall height (not much I assume).

Finally is there anyone that makes just a 1/2" spacer? Or will I have to use a 3/4" spacer with no isolator?

 

i think a stock isolator is ~1/2 inch. If i wanted a 1/2 inch lift I would just go down to napa, get another stock isolator and stack em up.

I use the isolator with the spacer. The spacers I have are harder then the oem rubber isolators and I didn't want to hear any clatter. I don't know anyone that has run with no isolator but i don't see why you couldn't. Isolator may help locate the top of the spring better than the spacer alone.

 

I make 1/2" all steel spacers...

or as housew mentioned you can just use an extra isolator, it will work great

 

I ran spacers without the isolators for a year no problems, Put the isolators back in when I did axle swap Just to level it out.
