4 link/ladder bar and coi over questions...

Postby Maaso » Tue Sep 28, 2010 1:58 pm

These questions pertain to my NEW truck, not my Vortec powered 4x4....

I was thinking about moving my leaf springs inside the frame to gain more tire clearance(and mini-tubbing.) But then I thought if I'm going through the trouble of moving the springs, I might as well just upgrade to a better rear suspension.

My first question would be about the four link, I'm thinking I want to go with a triangulated four-link so I wont have to run a panhard bar with it. And this set up is similar to older Chevelles and Fox-bodies, so there is proof out there its a proven set up. But is this set up any better than a parallel link set up? Or a ladder bar set up?

Next question would be how long do I make the bars? I know I want them to be long enough to allow my suspension to articulate, but I don't want them too long because then they might start to flex?

Lastly, how are coil overs for daily/street driving? Are they rough and stiff riding?

Length is normaly between 39 to 41 inches on a parrallel 4 link like mine. Coil overs will be fine for daily driving as long as you get the correct spring rate and a good shock. they make kits for the S10 and places like Compitition Engineering make universal 4 Link and ladder bars if you want to make your own frame railes and so forth.

Check out Checkered Racing, that's where I'm getting the 4 link kit and frame rails for my Vega, :thumbup:
