4 link rear
Hey guys, has anyone put a 4 link rear suspension setup on an 07-14 2wd Silverado? I had Scott’s Hotrods build me one for my truck but the link bars appear to be too short. The truck is lowered with a 9” and should make between 700 and 800 to the tires.

Can you post up the math? Estimated COG (usually about where the cam shaft is in height, assume vehicle center line for second axis) link length, link angles, pinion angle, ride height, link parallelism, termination points etc. Single/ double triangulated, panhard? How low? Whats the uptravel vs droop? Frame notched? Tubs? Tire size?
Immediately speaking, links below the axle is weaker for controlling rotation, and limits articulation, but its not 100% wrong, yet.
What we care about is does pinion angle change during suspension cycling, do you have enough/too much anti squat, is the passenger "upper" link adjustable to keep the driver front planted on launch (track tuning), does the suspension cycle freely, can you get into and out of steep driveways without dog legging and does it drive straight. Theres other, but lets start there.
I wouldnt build both bars below the axle, that is stupid and ugly, but if the math checks out (which I dont think it will) then it *should be ok.
Can you post pics?
Im not claiming to be an expert here, but Ive built a couple street trucks, several desert trucks and as stupid as it sounds, I am huge into RC crawlers and while the math is smaller, its no less important. I will try to help as I can.

Thank you for replying. I have some new information. UPS lost one of the packages...soooo hopefully they find it fast and get it to the shop. I don’t have all those answers but, the truck is going to be a street and track vehicle. The frame is not notched but can be, it is not tubbed but can be, tires are 28x13.5x15s.
