Your springs are shot out.
Stock replacement springs will raise the car back up to where it should be.
I wouldn't recommend a +1" spring. Ive seen it many times where people weren't happy with
how high the *** end ended up. Go stock replacement.
ESPO is a great company. and has everything you will need for the replacement. Very fair pricing as well.
I would replace the rear shackle bushings while your at it.
