Traction Bars

I plan to make my own here soon for my truck and I just wanted to know what the idea behind the length of the bar was and how long it should be.

This is going to be on a stock suspensioned truck and I know that tire size does not matter at this point, but they're only 285's. It'll be on a crewcab short bed truck w/ a w/b of 156" but I don't think that matters.

I basically want someone to tell me how long the bar should be, and why...



(The Green part). Like my MS Paint drawing at work?

Re: Traction Bars

Find the trucks center point of gravity, by balancing the truck with 4 large jacks and when the truck can only stay barley on 4 points, find the middle of that point and that should be your center point. Draw yourself a green line from that point to your axles and you should get an idea where you brackets should drop down and how long.

Re: Traction Bars

Start with the truck on 4 stands. Keep moving the stands together till you can easily tip the truck equally front and rear. The middle between the stands is the center of gravity.

Re: Traction Bars

First off, nice drawing.

I made mine in the same plane as the rear section of my 2 piece driveshaft. They came out being just over 6 1/2 feet long on my SCLB. I do have my rear mounts canted slightly rearward, and my front mounts are also canted slightly rearward, FWIW.

Mine work, plain and simple! I took 15 minutes to mock it up, and the engineer at work took about 45 minutes to make up a nice drawing and all on his CAD software to tell me I was right where I needed to be.

Re: Traction Bars

if running a single bar set-up what are you attaching the rear of bar to ? on my friends D-max he put a bracket on the bottom of the u-bolts for the springs but that won't work on the Fords.

thanks

Re: Traction Bars

I tried to match the angle of the drive line but wanted to mount to the frame where it flared out to full size. Mine ended up being 85" or 7'1"(the same as Tank mentioned). My hook Sat night was the first time I had no wheel hop.
