Coil Springs
I am working on improving my ride quality. I have ordered a BD Diesel adjustable track bar and new Rancho 9000s. I also have a Rancho dual stabilizer (might not be necessary but I think they look good if nothing else) heading my way. All of these decisions were made after searching every related thread on FTE. I stopped by one of the big 4X4 parts retailers and was told that the single best change I could make would be eliminating the 2 1/2" spacers up front and going with new springs. The Icon dual rate springs were recommended but the price is steep...about $425 or so. I see Rancho offers springs that provide 2 1/2" of lift for about $140. Would these be a significant improvement over the existing setup? Would it be as simple as swapping out the currently installed springs and spacers for the new, taller springs?

Off the shelf Rancho’s are the softest. Many aftermarket lift companies don’t bother with specking out a proper spring rate for the V-10. it is usually the diesel spring. Even the fabled Carlie lifts just use the springs they have developed for the diesel. This is disastrous because diesels weigh an amazing 760 lbs more than the V-10. I started out with Rev-Tec springs and they turned out to be Diesel rates and ridiculously stiff , then I went with a set of Rancho’s rated for the v10 and they were “OK” . Still quite stiff. I got a custom set of springs from Deaver for $450 and they are cush. If you want cheap cush get some Rancho’s but for the V8. The v10 is just a v8 with two more cylinders. Not much added weight. I would also suggest Bilstine 5100’s , rancho shocks aren’t that good. You need good shocks if you go soft on the springs.

Talk to Junior at ATS about your springs. They are a forum sponsor and good to work with.
Some guys like the RS9000 shocks and some (like me) like the Bilsteins. Neither product is horrible.
Your dual stabilizers wont do anything at all for ride quality.

I installed the stabilizer and front shocks last night. Pretty easy install even for a non-mechanic like myself. I will install the rears tonight and take it for a test drive. I am thinking about setting them at 5 in the front and 3 in the rear when unloaded. That seems to work for a lot of guys based upon what I have read. I will have a professional install the track bar next week. The truck is going back in the shop next week to get the rear differential drained (break-in on the new 4.88s is complete) and inspected. I'll just have those guys take care of the track bar at the same time.
