Porterbuilt 4 link or trailing arms

[Silverbird]

I just sent this same question to Nate as well but i'd like to hear thoughts from
all the suspension gurus.
I just ordered a complete front and rear dropmember touring setup yesterday.
I ordered the 4 link setup. I am having second thoughts on the rear and wondering if trailing arms might be a better route.
I want a very low static ride height with the best handling and ride quality as possible.
I am running a Ls3 that has a cam and some tuning.
I would guess right at 500 horse power.
Any input would be greatly appreciated.

My front dropmember and rear 4 link setup fron Nate is scheduled to arrive Tuesday via the big brown truck. I went with the 4 link as well for the rear. To me it is lighter, easier to adjust for pinion angle, makes for alot more room in the middle of the frame, as I plan on doing the bracing he has shown on one of his chassis with a four link. Plus as an added benefit, I think it looks better. What do you have for specific concerns about the 4 link rear?

I read in a post that Nate prefers the trailing arms to the 4link unless you are making serious power. It got me questioning the pros and cons of each.

How big of a tire/wheel combo are you planning for out back?

The truck arms allow for a larger/wider set-up. Truck arms are also longer & the longer the bar, the better the ride quality (even when comparing different 4-bar set-ups).

Running 10 wide now would like to run 12.
Do trailing arms ride noticeably better? Does either setup corner better than the other?

I know you posted this a long time ago. Which system did you go with?

I was putting almost 600 HP to the wheels with 31x16 Mickey Thompsons. I don't think any suspension would have helped it hook up...........

That's about the power that I'll be at with the motor. Would like to spray it at some point but need to get the traction figured out first. Looks like you had trac bars from ridetech? I'll have the boys tank behind the axel and battery relocated to the back. We were able to set the Motor and trans back 3-4" and the 4l80 moved some of the weight a little farther back too.

What's your thought on 4 link vs the bars? Any other ideas to get it to hook? I've always heard those MT tires look cool but don't hook very well. I intend to do a mini tub to fit 345/30/20 under there. Guess I can get another set of rear wheels for some slicks too.

I had a set of 3" drop Porterbuilt trailing arms underneath and my motor was all the way back (check out my 68 Farmtruck thread), but there was just low end torque for the tires to hold. A 4 link might help some because of hte adjustability. How much are you lowering the truck? If you slam it, check out my ChubTubz thread. If you decide to get the pedal bracket, let me know and I can get it shipped today.

I was looking g at porterbuilts stuff too. Think the touring set up is what I like. Already have ridetech control arms and plan on doing adjustable height coil overs. I need to do a little more reading. I'll check out those builds.

Also I'll get back with you soon on that bracket. Probably going to need one. Thanks.

I'm not sure if I'm going to hookup well or not, but I went with Porterbuilt's trailing arm setup. I will also be running their inner frame stiffener, Ridetech HQ shocks and on air. Having the ability to set the pinion angle with their TA crossmember ought to help. However I will only be running 400-450 to the wheels (est.).

Nice. I need to call and talk to them. The frame stiffener is something I'm probably going to need too. We hope he motor is going to put out 650 or better at the crank and I'd like to hit some spray at some point. Doing everything o know to do to get to that point. No that I know a damn thing. Lol.

Anyone else have any experience or info. I'm trying to decide which route to go also.
