TO OCCUPANT & VEHICLE
In Stock Class, where John's major racing endeavor has been shaped, NHRA dictates that a maximum of 9" slicks can be used. This presents a racing dilemma to a driver when trying to couple big block power to the ground. The CALTRACS design was developed in John's garage. Brainstorming together, Larry and John created the design and the first model of the system. CALTRACS augments the car and driver potential to specific performance goals while complying with hard set NHRA class parameters.
John's concept won the enthusiastic approval of his family. Two brothers, Keith and Paul and Dad, Bernerd all share a talent and fascination for the world of mechanical engineering. Combined they hold over 75 years of career involvement in Aerospace engineering and production.

Tremendous benefits can be realized when the CALTRACS traction
bar system is installed on a leaf spring suspended Street or Strip car. CALTRACS
traction bars and suspension products were developed to achieve specific goals to improve high
power traction while staying within hard set NHRA and other sanctioning bodies parameters.
Each of the two Caltrac bar assemblies needed is comprised of three basic components:
1. Front Pivot
2. Force Transfer Link
3. Rear Mount
The combination of these components changes the pushing point on the
car by redirecting the turning action (spring wrap-up) of the rear axle
through the Force Transfer Link into the Front Pivot. The Front Pivot
Spring Stop Bolt resists this turning motion and also controls the bending
of the leaf spring at its thinnest section. The push into the Front Pivot
helps the cars weight shift towards the rear of the car because of a new
directed angle of force toward the front of the vehicle. (The "Instant Center"
moves farther forward). This is where the system emulates a Four link system.
The pinion angle is also maintained. (See illustration)
1. The Front Pivot
Two steel plates sandwich the leaf spring sides. Two attach points
in the plates provide the user with a selection in which the forward Force
Transfer Link rod end can be located. A machined aluminum spring eye bushing
and steel insert supports the front of the spring while allowing the plates
to pivot. A spring stop bolt controls and restricts spring wrap-up. Spacers
are provided for different vehicle applications that control clearances
in the front spring eye pocket.
2. Force Transfer Link
This is a length of chromoly tubing with CNC machined threaded inserts
TIG welded into each end. The front Insert is machined with right hand Threads
and a HEX outer shape for Simple wrench adjustment of the Installed assembly.
The rear insert is Left hand threaded. Opposite thread Styles at each end
provide the means to easily lengthen or shorten the link for desired pre-load
adjustment.
3. Rear Mount
A welded ¼" steel assembly replaces the original vehicles spring
perch and incorporates the mounting provisions for the rear rod end of the
Force Transfer Link.
CalTracs Split Monoleaf Springs
| Calvert
Racing, the company who introduced the CalTracs Two-link System is
proud to announce our "Split-Leaf Mono" spring, an
innovation in leaf spring technology. This revolutionary concept
allows you to have the proper spring rate, and desired ride height for
your high horsepower racecar or boulevard cruiser. Calvert Racing has
provided 2-piece springs used by the last 5 World Champions in Stock
Eliminator, now you can own these same proven springs.
These are not a replacement spring designed to be used on a totally stock application, but if you have a performance street rod or muscle car you'll be amazed at the ride quality and improved traction of these springs when combined with the CalTrac Bars.

Installing the CALTRACS is very straightforward. Raise and support
the car high enough to remove the rear tires. Allow adequate working space.
Next, the rear spring assemblies should be removed. This will facilitate
replacement of the front eye bushings. Support the rear end housing in
place while the springs are out. This will eliminate the need to disconnect
the drive shaft, brake lines etc. Press or have pressed, the original front
eye bushing out of each spring assembly. Replace these with the machined
aluminum CALTRACS bushings supplied in the kit. Now, reinstall the rear
springs into the car.
With each spring assembly ready to go in, position the forward pivot
assembly to the front spring eye. (Assure that the Spring Stop Bolt is
located on the upper surface of the spring.) Install the Steel Bushing through
the pivot and front spring eye bushing. Now, reinstall the spring using
the original hardware. Repeat the process for the other side.
Lower the rear axle assembly on to the springs. Install the supplied
spring perches as you would the stock items being replaced. Attach the
shocks.
Now the Force Transfer Link can be installed by starting the HEX (wrenching)
end on to the forward rod end. Remove the rear rod end from the spring
perch and start its threads into the rear Force Transfer Link. Adjust the
assembly to proper length by holding the rear rod end then rotating the
Force Transfer Link until the rear rod end will line up with the mounting
hole in the rear spring perch. Install the rear rod end fastener and secure.
With the CALTRACS installed and the rear tires reinstalled, lower the
car to the ground. As an initial setting, turn the Force Transfer Link until
the spring Stop Bolt just contacts the upper surface of the spring, then
turn the Force Transfer Link one turn more to establish pre-load. Tighten
the Force Transfer Link lock nut. That's it!
