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.

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.
In addition to improving consistent 60-foot times, Calvert Racing's patented CalTracs eliminate axle rotation AND improve traction, especially on hard acceleration.
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.
Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint's life and could create vibration. If your angle is larger than 3 degrees, you must make sure not to exceed the max driveshaft RPM as shown on this Spicer table.
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.

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.
