Lift Kit Help!

I was going to install my front spring spacers and rear leaf myself but a friend told me it was something I can't do it myself because the spring in the front is under too much tension. Can I install a spring spacer and add a leaf on my own or should I have it professionally installed?

 

You can borrow a spring compressor from autozone. What type do you have? I see no reason why you couldn't do this my yourself, I did mine but I changed the coil springs and just added a block to the rear.
There should be some instructions with your kit, if you have a kit, mine instructions were very good from toytec.

 

most spacer lifts will not need a spring compressor. get some C-clamps for the leaf springs and a friend to help spread the front control arms and your rockin and rollin
