4 link !

[78-5.3]

does anyone now where i can buy a 4 -link kit with the 4 bars rod ends and brackets!!! that i could fit to my truck im not interested in the air ride suspension ! this one from brothers is what im looking for but i want the 4 bars to be on the inside of the rail anyone personal installed one of these kits ?? pics ideas i want the install it on the inside for a massive tire !!!

They call that a 4-bar suspension to keep it distinguished from a drag car 4-link.

The 4-bars are common hot rod stuff so I would do some searching for hot rod parts vendors.

The difference is the 4-bar has no alternative mounting points for the four equal size bars and they are parallel with each other and the driveshaft plus it uses a panhard bar to locate the rear end side to side. Really simple to install and set up.

The drag car 4-link uses different length bars top & bottom and each bar mounting point has several alternative locations so you can change the characteristics of the suspension system. It is also located side to side with a diagonal link that is connected from the front on one side to the rear on the other. It does not allow for much body roll at all.

There is a version of the 4-bar called a triangulated 4-link that uses angled upper & lower bars that point inward at the front in different locations top & bottom that does not need a panhard bar. This is what GM used from 64 to 88 on A-body & G-body Chevelle & Monte Carlos and all their clones plus a few other cars. Quite a bit of chassis engineering math involved in setting it up to work well but when done right it is very nice.

It wouldn't be any big deal to put it all on the inside of the frame rail. It would just need some boxing of the frame rails in the mount point areas to give you somewhere to bolt it up. A simple rectangular tube crossmember could take care of this too. A generic application hot rod parts package would probably do it this way.

ive seen them @ chasss online vendors and hotrod places lke chris alston chassisworks but im looking for something that i can buy that will work with the trucks dont mind fabbing it some after buyng it but im looking for the right parts to buy
IE - BAR LENGTH FROM TUBE BRACKETS TO BRACKETS ON FRAME
there must be a set up out there like brothers that will work and require minamal work to fit a c10 truck ! a 4 link or 4 bar setup like this !!

[78-5.3]

CHRS ALSTON CHASSISWORKS HAS A KIT!!! they also have a 74 c10 in there how to section!! the kit is called PKG U $789 gets you most of whats needed to make it a 4 bar with lots of ride height options i will get this kit in the spring!! couldnt cut and paste the pic for some reason its in the chasss work catalog 16
page approx 133

[3r!c84]

you can buy all the hard wear and make it your self too?
like what all the 4x4 guys do

[gmclowsierra]

the reason the drag race kits have adjustable holes in them is to adjust for track conditions. you can also change the instant center oin the car so it will hook better. either kit will work but the adjustable one is better. a little harder to setup but not much. are you going to drag race this thing or just street drive it?

What about that KP 4link system? I had looked into it a while back. They have a bolt on setup for our trucks and I'm sure you could modify them to fit inside the frame. I don't have the link anymore, but I'm sure somebody around here has heard of it or looked into it.

KP is a Chassisworks sub-brand. Their catalog is on the Chris Alston web site. Lots of neat stuff for our trucks.

Are you talking about the Battle Cruiser 4-link package?

What exactly are your plans for using this truck? A drag race 4-link package like that with all spherical rod ends will not last long on the street and is kind of noisy.

If this is meant to be a street truck I would go with something that has polyurethane rod ends and not spherical bearings.

If you are going to run that 9" rear end then a triangulated 4-link like is on pg 14 of the KP Components catalog will work great. Add in a set of coil over shocks like on pg 33 of the VariShock catalog and you are set. About $940 but well worth it to have poly bushings instead of spherical bearings.

Those look like non-adjustable coil over shock mounts on the back.

no i dont wanna race it i just wanna decent suspension and be able to run a big tire under it!!! with out fouling suspension conponents s that why wanna run in board suspension

The triangulated 4-link is easy to mount on the inside of the frame rails so it will give you room for a huge tire close to 18" wide, maybe more depending on the sidewall flex and your ride height.

How big is a big tire to you? You can run a 325/50-15 drag radial on a stock truck arm suspension with a lot of clearance. I ran them on my 67 C-10.

My 78 K20 has 16" between the leaf and the inside edge of the fender lip so there is enough room for a 14" wide, tall sidewall tire with some room for sidewall flex without damage to the tire even with the truck in the weeds.

If you are just looking to run a big tire under the truck im running a 29-15-15 MT on my truck with stock suspension

It seems like the 4 bar setups cater more to the people who do air ride. The bars are parallel so it keeps the pinion angle constant, whether slammed or lifted.

A 4 link will not have the links parallel to each other. Instead they are angled together, which helps weight transfer and helps the tire bite better. A drag car 4 link can be adjusted to give more or less bite to give the best launch.

I would much rather have a 4 link that's geared toward traction, even if I wasn't racing.

Looks good. Don't forget with that you will need an air compressor, storage tank & control system to manage the air bags.

I guess you could just set the pressure you want at home with the shop air source and hope it didn't have a slow leak.

A small on-board air compressor could take car of that though or if in-field adjustments were needed.

SEAMs cheap in price hopefully not in quailty !! i think that would be easy to install i wonder if it been done by anyone here???

It looks just like the KP Components triangulated 4-link universal kit but with air bags. The KP kit is only $399 so if you added a set of budget coil over shocks & mounts you could be less expensive and not have the hassle of air suspension to deal with.

You could even go with regular shocks and coil springs from a truck arm 67-72 application for a bunch less money.

The popular one with leaf spring drag cars is the Rancho RS9000X adjustable one. About $90 each.

I plan on getting a set to replace the generic adjustable ones on my car now.

I have heard good things about the Edelbrock Performer IAS shocks but have never used them myself.
