I'm curious as to how that system was working on bracket/NSS cars? Have you folks that are using them had better success than using leaf springs with rear shackles and if so, what performance levels were achieved? How much lower did the car set after the slider installation and were there any detrimental effects? BAM, let's hear what's going on after these modifications were accomplished, THANKS! 6807804-springsliders.jpg (576 downloads)

My best guess is that it will lower the rear of the car about 1-1/2". It is about a 3" difference at the shackle end of my springs. I went to a Dave Morgan Seminar, and he was a big fan of the sliders. From what I hear they work well. I guess I will find out first hand. -Kenny

Lowered the car about an inch. 13 runs on it since The car was completed and so far so good. 6808323-2011-06-1116.02.11(Large).jpg (624 downloads) Last edited by Todd; 09/03/11 10:50 AM.

They would work a little better if they were angled with the arc of the spring. I used them as it was easy to fit them against the frame. I notched the front frame to get the springs as high as I could sense we are no longer planning on hauling wood. LOL Have not ran the truck yet. Owner has really slowed down on me.

How long are they ? What is the full travel of them ? And why would they be better then shackles that are mounted right ?

They ride on a bearing which is free VS riding in rubber which tends to bind then snap free... its just smoother

From memory when I installed them, the spring eye is to be around a 1/4"-3/8" past centre, toward the rear of the car. I think there is install information available on the Afco site, which I suggest would be worth looking for. Alan Jones

In their opinion the did not improve your suspension over a properly set up shackle. By "properly set up" they meant no binding and the correct working angle. This was one month ago.
