Since you are 2wd, I highly suggest going the suspension route in the form of a Spindle. I say this because well...I prefer suspension over bodylifts. Espicially since you can get spindles for a little more than a bodylift. Compared to 98+ 4x4's, lifting a 2wd is CHEAP!! 98+ 4x4's run a cool $1500-1700 for the cheapest suspension lift.
Back to your question...
Well...there's only 1 manufacturer of bodylifts for 98+ rangers....Performance Accesories(PA). BUT.....If you go to SummitRacing.com and look for a bodylift, they carry their own brand bodylift, and it's made by PA and costs about 75% of what the PA costs. Go get that. Like said above, if you are a manual trans, get a shift extention. Part number 3700.
