I dont think there is anything wrong with coils. Everyone who has rode in my 05 seem to love the smoth ride. In the past I owned a jeep tj with 4 coils around it and it out performed any stock cj or yj with leaf's. It also drove smooth. It's one of the key features behind my choice to buy the new F250 SD 4x4.. Also it will move and flex more freely than a leaf spring due to the absence of friction.This seems to be one of those topics that will turn a good conversation into a war but thats just my thoughts...

Yes. Why wouldn't it? It's still a darn spring.

And no need. One of the MAIN reasons that coils are used up front is to reduce turning radius. The 250/350 TR was reduced 5 and a half FEET!

I would also argue, respectfully, that a coil over set up would actuallly have a higher amount of friction (actually stiction) over a traditional leaf spring set up. The radius arms have 3 areas on each side that stiction can come into play.

Well I guess that if you can hang that plow on a stock f250 with leaf's and plow prep. now that the 05' with all it's upgrades working together giving a higher GAWR of 6000lbs @ Ground, the coils would carry your 800lb vee blade. In reguard to the rear I dont know the answer to that. But for a system that lets you turn tighter ride more comfortably I'm all for it..

Not to bring up the competition but Dodges have had coils since the current design came out. The straight axle is still there!!! They could have put a junk independent under the front.

I forgot to address that.

Why not use them in the back? Because leaf springs setups are cheaper and coils will not give you any advantage over leafs OUT BACK.

Because the nature of a leaf is suspension and self centering. If you had rear coils, you'd need upper and lower control arms to keep the axle centered, just like the new fronts have. Make sense?

I believe come IRS utilize coils. As do many rock crawling rigs (much better articulation). Besides, why fix what's not broke? The current leaf setup does it's job just fine.
