FAQ
The harder you're on the throttle, the harder the downward force on your tires. While many believe that CalTracs are strictly for drag racing applications, a properly adjusted CalTracs setup could improve traction for just about any application, including heavy towing, off-roading, even daily driving.
Split Mono Leaf Spring Design & Construction Parabolic leaf springs are an evolution of a conventional taper leaf spring. Here (in the case of a Calvert spring), the rear segment leaf is thicker at one end, and then it tapers from the middle to the end, where it is thinner.
In addition to improving consistent 60-foot times, Calvert Racing's patented CalTracs eliminate axle rotation AND improve traction, especially on hard acceleration.
CalTracs: Accept No Substitutes! Patented Traction Bar system with designs for axle above or below springs. Bolt on kits for nearly every leafspring application. Hooks your vehicle, especially on hard acceleration, even in the dirt! Improves consistency and 60-foot times.
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.

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

Calvert Racing - 42156 10th Street West - Suite V - Lancaster, CA 935364 Phone: 1-Park truck on a flat work area, chocking the front tires is advised to avoid rolling. I run Cal tracs on my Falcon and on street tires it does not hook up at all. Traction is much better with the Drag radials and they work great at the track. I'm gonna show you how to do it without needing any specialty tools so you're not going to need a hydraulic press or any kind of especially. When you install the Bar you want it to be parallel with the ground. I had to use the bottom hole. Collegiates may have to fill out a DD Form 1172 at the NAVTALACQGRU to gain access to the local military installation.
