In addition to improving consistent 60-foot times, Calvert Racing's patented CalTracs eliminate axle rotation AND improve traction, especially on hard acceleration.
It uses a single ladder bar that attaches to brackets welded onto the axle housing, in front it attaches to the frame with a shackle. This arrangement prevents the axle housing from rotating under acceleration and braking while still allowing the suspension to move through its range of travel freely.
The pivot at the front leaf eyelet then forces the pin riding on top of the springs downward into the spring pack itself. This downward force of the pin on the leaf springs causes down force on the entire axle assembly and pushes your tires down onto the pavement/dirt.

Those those leaf springs traction bars lock onto the leaf spring. And when they go to warp. TheMoreThose those leaf springs traction bars lock onto the leaf spring. And when they go to warp. The traction bar jumps up so this part here jumps up and hits the leaf spring which prevents wheel hop.
Most driveline companies recommend operating angles of 3° or less for maximum u-joint life. There should be a minimum of ½° to allow the needles to rotate. The higher the operating angle, the more likely your vehicle will develop a vibration at high driveshaft speeds.
Pinion angle is the key. Once you have the traction bars installed you'll want you pinion angle to be negative 2.5 to negative 3-5 degrees.
Either way, you are ultimately looking for pinion angles of 1-2 degrees above the drive shaft angle in the front and 1-2 below drive shaft angle in the back. Theoretically zero is perfect, but the offset allows for axle wrap (twist) under power.
