65 trailing arms VS 4 link

[baggedbigblock]

I searched the site already. My truck is at the fabricators right now, I want a budget build for a 350hp truck, no drag racing just fun on the streets.

I have the bag setup already and we are putting 2.5" spindles and bags up front and the rear I am not sure about.

I was going to just bag the trailing arm with a 3" block and fab up a rear bar, the fabricator says I will have left to right movement when I raise and lower the truck. I plan on running 295/50/15 tires on 15x10 and I dont want to worry about the sidewall hitting one side or the other. I dont want to cheap out either but I am not sure if I need to spend 350 more on a universal 4 link.

To give you a better idea, I plan on parking on the frame, riding 2" off the ground and then fully inflating only over curbs/speed bumps. I figure he can set up the rear to be level at ride height and with a bag in factory spring location will I really get that much side to side movement?

Use a Panhard bar that connects to the pass side truck arm vs. the shorter factory location @ the top of the differential housing. The longer bar would help minimize side to side shift. How much movement will depend on how much total travel there is for the suspension.

thanks, we will fab up a bar and test it out. I plan on aligning the truck at 2" off the ground and prob a total of 8" of lift, however much a 2600 bag can lift in stock spring location.

Because of my wide tire setup are we talking 1/4" 3/4" or 1.5" movement?? I just dont want the tire hitting the fender.

Prob < .500".

Just draw it out on the shop floor, you can readily see and measure the amount of side movement for any given vertical travel, as the track bar (panhard) swings through its arc. Or, of course, get someone to do it on CAD. I'm old-fashioned (wonder why), I like seeing it full scale.

Exactly. This is how I checked it in the past when comparing a 'short' factory length Panhard bar vs. a long bar.

I used the factory bar & a yardstick @ 36" w/some chalk in the driveway. I marked a reference spot @ level (ride height) & then marked reference spots @ +3/ -3" of up/down movement. Determine what range you'll have for your suspension travel, what length Panhard bar you plan to use, plot it out on the driveway, measure the difference, & you'll know what kind of shift to expect.

Thanks alot guys, I will set it up and see how it comes out.
