"3-Link" Traction System

 
Across the ocean, there are many Mopar gearheads. There is a problem in that international shipping gets very expensive, faces many extra taxes and tariffs, and just plain takes forever. Alot of guys outside the US tend to solve these problems by making their own parts instead of buying them. This product is one such solution. Although there are similar systems available, like CE's "Slide-A-Link", and Caltracs, Mike Dyrlund does make and sell this one from his shop in Denmark.
The links are made from 1" chromoly tubing with 14mm rod ends. Attachment plates are 6mm steel which are Tig welded to the bottom of the spring/shock plate.

The blocks under the axle are merely lowering blocks. Mike says with the bars in there, he has no problems using blocks to lower the car. That's impressive considering Mike's Dart in in the high 9's. Normally, using blocks greatly increases leverage on the springs and spring wrap can be quite excessive.


 
The front slider consists of tubing welded perpendicular to each other. One tube slides onto the link bar, with the perpendicular tube pivoting on the front bracket. The front mount pivots up and down, while allowing the length of the bar to change as the suspension moves. This allows bind-free motion of the bars.
Axle torque is handled by the bars instead of the front spring section, eliminating spring wrap. Softer springs can be used since they no longer have to handle such high stresses, allowing a better street ride, lower stance, and quicker reaction, yet the full amount of axle torque is converted to downward force, planting the tires under acceleration. When using these bars, pinion angle can be reduced to just 2 degrees down.
To get the same results with leaf springs, ladder bars would have to be added, along with housing floaters to eliminate binding. A considerable expense compared to these. Granted, a full ladder bar setup provides much better leverage, but for the price, it'd be tough to beat an arrangement like this. Mike states that many racers in his neck of the woods use systems of the same basic design, and that 60' times of 1.30-1.35 can be handled without damaging leaf springs.
