DIY adjustable sway bar

This was done on my XP turbo. With the stock shocks I ran it with the rear sway bar disconnected. It's seemed to handle just as good, but it articulated better for the slow stuff. Recently I put on shock therapy 3+ Springs, which is four new front springs and rear upper Springs along with crossovers. It made a huge difference and it rides much smoother. But, it had ridiculous body lean with the rear sway bar disconnected. So I hooked it back up and it handles good again. But, it lost the articulation on the rear. So I made up some plates with multiple holes and welded them to the trailing arms, so that you can put the swaybar link farther back towards the shock which makes it stiffer, but you can also put it towards the front of the trailing arm which makes it a softer sway bar. I also welded two pieces of half inch angle iron to the swaybar links to make them stronger. Total cost......zero!!! I'll be trying it out tonight to see how it works.

Re: DIY adjustable sway bar

It worked just like I thought it would. I got it set to be softer than stock.

Re: DIY adjustable sway bar

In this picture at the four-inch Mark was the original swaybar mount. I tried it 4 inches to the left and it was actually too soft there and it would take a set when you were cornering making one of the front tires feel too light. So now I am at 2 inches from the original mount and it feels like a good compromise right there.

Re: DIY adjustable sway bar

Your fabrication skills look nice. I'm surprised this affects the stiffness of the sway bar, since the same amount of sway bar is sticking out from the fulcrum point, (sway bar brackets). I would think you'd get better stiffness by drilling a new hole in the sway bar, closer to the firewall, so it doesn't allow as much flexing.

I guess as you move the bottom link bolt, it just changes the effectiveness of the sway bars torsion rate, due to the increased angle?

Re: DIY adjustable sway bar

As you move the lower mount towards the rear of the trailing arm, it gets closer to a 1:1 ratio making it stiffer. If you move it towards the front, the trailing arm moves less and has more leverage, making it softer.

So the stock mount near the middle makes the sway bar about half as effective as it would be if mounted right above the axle.

Re: DIY adjustable sway bar

So this is working great. I put it in the farthest back hole which is the stiffest for Glamis a few weeks ago, and it cornered like it was on rails!

Re: DIY adjustable sway bar

Just saw this. Great idea! BTW are you using dryer vent tubing for your clutch housing tubes?

Yes...............
I didn't like how the oem hose was 3" at the bed and 4" at the housing. And I can't find the good black 4" hose that some vendors use with their setups.
