I am currently gathering parts to do a front end overhaul on my 2008 Navigator with 113,000 miles on it. I have so far replaced the tie rod ends (Motorcraft), sway bar bushings ( Motorcraft), Drop links (Motorcraft) and new pads, calipers, rotors and brake lines (all Motorcraft). Next is the major suspension parts, upper and lower control arms, shocks and springs. My question is what aftermarket companies make good springs for my Navigator. I know Moog makes a set for $100 but I'm not sure about the quality vs Motorcraft which is a ridiculous $160 per spring on Official Ford Parts Site | Buy Motorcraft & OEM Ford Parts Online | FordParts.com . Does anyone else have suggestions on where to look at? Before someone says it I know most people will reuse springs when putting on new springs but I elect to put new springs on to have a true front end overhaul.
