Should I use Leaf Spring or Coil Rear End?

Sorry if this has already been covered, What is the advatage of either, I am putting one or the other under my Suburban...I already have one of each...which would ride, and handle better? I plan on occasionally towing so I might try to beef up the springs a little.

Re: Should I use Leaf Spring or Coil Rear End?

coils will give a smoother ride....there are pros and cons with each, but my opinion would be to go with the trailing arm/coil set-up

Re: Should I use Leaf Spring or Coil Rear End?

Thanks, it already has the coils, but if the leafs would work or ride better I have a trailer that I could rob the parts off of...I guess I will leave it alone unless somebody else has a suggestion

Ditch the coils, and install air bags on the trailing arms. you dont need a super fancy kit. just some 2500# bags( each) and a small compressor. you can adjust ride heigth, and load capacity for towing

I am not a big fan of the air bags (sorry lowriders) I would use them on something driven occasionally, but I am going to mile this thing up, I have had to many bad experiances with Lincoln Mark 7's to ever trust an airbag....I know they work great, when they work, but I hate being stranded though and shocks and springs have never done that to me, bags have. If I ever build a truly recreational truck I would go that way though.

Re: Should I use Leaf Spring or Coil Rear End?

My experience is that the leaf springs will tow a heavy load better than a coil spring rear end. The coil spring rear suspension tends to bounce a lot more than the leaf spring rear suspension. I'd try towing with the coil spring rear suspension first though since it's what's in the Suburban now.

I do not understand what you mean? Please explain how the airbag system is different in a truck? My Lincoln used Goodyear airbags and had small plasic lines ran to an onboard compressor. I realize that the Mark had level sensors, I know this because I would have to crawl under the POS to trip them, and valves, but it looks alot like the ststems I've seen here....another thing I was not to fond of was the Cadillac ride, I don't need that in a truck, I like bouncing around a litle, after all it is a truck.

Re: Should I use Leaf Spring or Coil Rear End?

Leaf spring rear is stronger, and maybe a little stiffer. I have 1 leaf out of my 72 GMC with 2" drop shackles and still put almost 2 yards of mulch in the longbed. Burbs are a little heavier in the rear as well, I would say install a leaf rearend.

Re: Should I use Leaf Spring or Coil Rear End?

in my opinion (i agree with you) the car set ups are junk, and way overpriced.
my point was, the majority of the semis on the road have air ride with very few problems.
but most of the luxury cars seem to be plagued with issues. I believe the aftermarket stuff has more in common with the big trucks.
if you want a firmer ride, i have heard the dominator bags are the way to go.
don't rule out a simple replacement of the coils with bags, you could just run line to schrader valves and have them at a static height with the ability to add air for towing/hauling stuff...
my main point was don'tlet your bad experience with a lincoln ruin your perception of airbags.

Oh, don't get me wrong I like airbags, I just think the are more for a cruiser than a worker, I pull trailers alot, I have a bad car habit I can't seem to shake !!!! It is so bad I got a Dealers Lisc. a few years back, The reason I bought this was for LONNNGGG parts runs....and i just would hate to blow a hose or something on I-80 in the middle of Summer !!!! If it was purely a recreational vehicle, like a slammed shorty it would have the bags, I just think they would be to expensive and add another thing to fail at the wrong time for this project, I would be willing to change to leafs, but as suggested I am going to give the the coils a try for now ( I think ?). As far as Lincolns go, I actually liked that car when I had it, just some engineering problems, but those are always present on luxery models, thats why I drive trucks.
