straight, triangulated 4 link is not that important to me. when i think of hooking up i think of weight transfer which IMHO is more important. 4 links are by nature are short, Ladder bars are slightly longer. the trailing arm pivots on a coil spring rear c-10 are about 48" forward of the rear axle. the further forward your pivot point is the quicker your weight transfers to your rear tires. Also maintaining a minimum -2degree rear pinion angle and the compression and rebound of your shock settings are critical to staying hooked up. look at Kevin T's passtime run he ran(correct me if i'm wrong kev) boxed trailing arms and coilovers w/ a 10" or 12 inch slick and shot 350HP nitrous to his BBC dead out the hole and his 68 stood up was GONE! I made my own 50" 1"x.125 chrome molly ladder bars& panhard bar w/ QA1 adjustable coilovers. moved the pivot point aprox 2" forward of the stock location under the cab and i have no doubt it will hook solid, also i have back halfed the frame w 2"x4"x.125 boxed tubing and tied it together diagonally underneath the truck with some more 1' x .125" chrome molly tubing adding rigidity to the frame. I used 1" tubing because the truck has been lowered 4.5" up front, 6.5" rear and i'm running 3" exhaust between the frame rails on the street. i worked in a chassis shop for 10+ years i have no doubts in the design. My truck is going to paint 3-1-12 and will be completed by 4 july 2012. personally i would only use 4 link setup on c-10 if i was bagging it. just my 2 cents.
