For the rear, a flip kit will lower the truck 5". OR....you can do the flip kit with 2" chevy drop shackles(which lift rangers), and it'll lower the truck 3".
I highly suggest a DJM 4/5 kit. Will work on all 98+ Coil Sprung Rangers/Mazdas. They also have a 2/3 kit as well.
But......you gotta tell us what your truck is! is it a 2wd XLT? 2wd SPORT? 2wd XL? 4x4? What is your truck.
