a little help please
 

Hey i was just looking at my shocks and i noticed i have de carbon shocks in the back from delco suspension and the shocks in the front are so old you cant even see the paint colour. My blazer has 280,000k so i was wondering some good on an offroading shocks i was thinking rancho but they are the only thing i know so help me out please!

If you plan on keeping it stock height I would get some bilstien shocks.

i wanna put 4" in total with a body lift and shackles and torsion

I like KYB shocks... but have had good luck with Rancho RS 5000's as well.

I currently have Pro Comp ES9000 on mine lovin em so far.
Only been on a week so cannot say how long they hold up but the application was for 1-2" of lift since I'm gonna be tweaking tbars as soon as finances allow for bigger tires (already have 3" body lift but that doesn't affect shocks)

would these be good if i had had just torsion in the front for now? (pro comps or rancho or kyb) and out of those 3 which would u say is the best for on and offroading?
