FAQ
In addition to improving consistent 60-foot times, Calvert Racing's patented CalTracs eliminate axle rotation AND improve traction, especially on hard acceleration.
By cleverly controlling the position of the rear axle, traction bars significantly reduce the bounce, keeping the rear suspension from excessive movement. This results in a smoother, safer, and more controlled ride, improving the driving experience substantially.

Traction bars are a must on any truck in all honesty. It allows the truck to shift a lot nicer, and keeps the rear end more stable. I'll never remove mine or run a truck without them. My truck needless to say is way more fun to drive and rides a hell of a lot better.

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.
We suggest a pinion angle to be between -2 to -4 degrees when used with CalTracs.
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.
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.
