Drag Racing & Sled Pulling


Jefferson State Diesel Nationals NHRDA Diesel Drags Fred's Truck Drags
Jefferson State Diesel Nationals 5th Annual Nor Cal Diesel Rally Fred's 6th Annual Truck Drags
The 2012 Jefferson State Diesel Nationals at Redding Dragstrip in Redding, CA featured diesel drag racing, sled pulling, a burnout contest, and even a show-n-shine competition. JH Diesel Performance hosted this event at Sacramento Raceway in Sacramento, CA. In addition to racing, a mobile dyno was present and many big names in the performance industry were on hand showing off their products. Trucks, gas & diesel, battle it out for top honors at Fred Owen's 6th annual truck drags, hosted at Sacramento Raceway in Sacramento, CA. This event featured a great selection of street driven & daily driven oil burners.

Diesel Drag Racing

Drag strips are either 1/4 mile or 1/8 mile in distance. There are several forms of drag racing:


Bracket Racing:

In bracket racing, the most consistent racer wins, not the fastest. The race starts in time trials, where competitors are given the opportunity to make several runs in order to find their dial-in time. Once selected, the dial time becomes their target elapsed time and the racers enter the Elimination round. In Eliminations, racers attempt to race as close to their dial times as possible - they do not race in a "heads up" style. As such, 2 racers with seperate dial times will receive the green light at different times. The racer who finishes closest to their dial in continues to the next round, while the other racer is eliminated from the competition. Running faster than your dial time is called "breaking out". Competitors who break out are automatically eliminated. If both racers break out, the racer who beat their elapsed time by the most is eliminated. The winners of eliminations compete for the title in Finals. Bracket racing allows any racer the opportunity to fairly compete, despite how fast (or slow) their truck runs.

Example of bracket racing:

Truck 1 dials in at 14.00 seconds, truck 2 dials in at 12.00 seconds in the 1/4 mile. Truck 1 will receive the green light 2.00 seconds before truck 2. Truck 1 finishes in 14.05 seconds, truck 2 finishes in 12.50 seconds. Truck 1 wins the race because he was 0.05 seconds from his dial in time, while truck 2 was 0.50 seconds from his dial in time. Theoretically, if both competitors have perfect races they will cross the finish line at exactly the same time.


Heads Up Racing:

In a heads up drag race, racers are given the green light at exactly the same time and the fastest racer wins. Heads up races are divided into classes in order to match trucks fairly. Each class has its own set of restrictions and guidelines; the NHRDA has 5 heads up classes.

Example of Heads Up Racing:

Truck 1 runs 11.00 seconds, truck 2 runs 10.00 seconds in the 1/4 mile. Truck 2 wins because he ran faster, simple as that.

Truck/Sled Pulling

In sled pulling, competitors test the pulling ability of their trucks. Sled pulling is divided into several classes, each with their own set of rules and restrictions. In sled pulling, classes are more often than not designated by the size of the turbocharger that can be used.


A truck is connected to a weighted sled and must pull the sled as far as possible. As the sled moves, a weight slides towards the front of the sled, increasing the force the sled exerts on the truck and making it increasingly difficult to pull. When the force becomes too much and the truck stops, the pull is over. The competitor who pulls the sled the farthest is the winner.
