FAQ
Calvert notes that its split mono leaf springs are designed to control and reduce excessive body separation in rear suspension and they can plant the rear tires without unloading. They're also considerably lighter than factory leaf springs (especially multi-leaf designs).
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 traction bars do really have a positive impact on your traction. The reduction in 60 ft. times is real. However...it takes a little getting used in tight corners, pulling in to parking spots, in and out garages, sharp turns, etc.
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.
Calvert Racing, Inc.
We suggest a pinion angle to be between -2 to -4 degrees when used with CalTracs.
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.
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.
In addition to improving consistent 60-foot times, Calvert Racing's patented CalTracs eliminate axle rotation AND improve traction, especially on hard acceleration.
