4 link it or not?

[Imacarguytoo]

I am thinking about running a 4 link on the 67. Using coil spring buckets and shocks. I do not want to run coil overs due to price.
Any racers on here run a 4 link on their truck and what do you think about it?

Just curious with doing that kind of huge modification and cost, what are you hoping to gain???? Is this for racing, or to accept a totally different rearend like a 9 inch? Big bucks and work if you are just using it on the street. One reason why I like the trailing arms on these is that they handle the axle wrap problem which usually leads to wheel hop.

I couldnt get any traction with the last c10 i had. I am building the 67 the same way. I have a friend that is a fabricator that told me he would do all the work for little to nothing. Yes i want to play on the strip a little bit. But mainly it will be a street truck. I am taking the 10 bolt from the 85 donor truck and wanting to convert the 67 over to 1/2 ton.

Interesting........

Obviously, I have no idea of the particulars, so I say this in very general terms....You have to be careful and not "polish a turd". In other words, think very carefully about exactly what you will have when you are done, and could that money and effort be better spent in another way or even on another truck. You did say it's a 3/4 truck right? If so, I'd have to say don't do it since your thread was asking that exact question.

I know I've seen something on this site about a 64-66 short fleet truck that was clicking off <1.60 60ft times using the stock trailing arm set-up.

The factory 2-link is like having 5ft ladder bars that have more articulation. The 4-link is the best for drag use (a true 4-link not a 4-bar) but the truck-arm suspension will stick if you set them up right.

This truck has been in the family for a while now. I want to keep it that way. Yes its a 3/4 ton. But like alot of others on here. They have converted over to disk brakes and some have made their trucks 1/2 tons. These trucks are pretty hard to find around here (where i am located) as parts trucks or to even find one that someone doesnt want a lot of money for. So im working with what i have in front of me. As i was told last nite by the 2 friends that came over. (we have a good welder and a plasma cutter, we can make what ever you want that will work)
SO back to the question i have in the title

Then....nothing at all wrong with making what you already have better!!!! You just have to promise to post pics.

Take a look under the cars used for Nascar---from the bottom, they look a lot like our trucks with trailing arms!! Easy to adjust, simple to align, strong as they need to be---only disadvantage I've seen is their ability to handle heavy loads. The trailing arm suspension has coil springs mounted much closer together then leaf spring suspension----that is why the GMC trucks all have leaf springs mounted way out on the axles--stock. They handle heavy loads a bit better with less sway. Trailing arms ride better with coils. For drag racing---you want a very firm axle from rolling or twisting but the real weakness here is not the trailing arm but the actual axle design. You would be much better off with a ford 8-9" modified design. Easy to change, easy to adjust, and stronger. My .02
