Lowering 02 blazer
 

I have a 02 4dr 2wd blazer LS and want to lower . I hhave 17 x 7 in rims and tires are 225x45x17 what route on lowering should u go front is 19.5 in from center wheel to bottom of fender and rear is 20.5 i was thinking 3 in all the way around here'https://cimg5.ibsrv.net/gimg/blazerf...70bf6ace4c.jpg a pic and what shocks and size should i get i want a good comfortable ride

Go with name brand shocks. Monroe, Bilstien, etc, should provide a nice ride.
How are you planning to lower it? 3 inches will make it necessary to install shocks that allow for the altered ride height. However, if you go with a 2 inch drop you can use oem spec shocks and keep the comfy ride.
Nice color, by the way. Post pics of whatever you decide to do. 👍

Very nice ride.

Looks like you're missing a lug nut (cover, or locking nut maybe?) on each of the rims shown.

lol yeah store didn' have all of them had to get the rest that day from a other store
