Street Semi Rules



 

2015 Street Legal Semi Rules:

This is a class for street legal and street licensed semi-trucks.  Trucks are expected to be regularly driven on the road.  This is truly an open class for all semi-trucks, but it is definitely not a PURE STOCK class.  Any truck that dominates in the class may be handicapped.  Lets all remember, we are all here to have fun and be safe.  Thank you and we hope you enjoy yourself this 2015 season.

LEGALITY OF ENTRY:

All entries must be a Street Licensed Semi Truck.  The owner must furnish a current registration card for the vehicle at the time of registration and the driver must have a valid license.  Truck must be capable of pulling a trailer on the highway.  You may trailer a Street Licensed Semi Truck into a pull as long as the truck that is pulling the trailer will also be pulling.  Before a truck even hooks to the sled, it was be teched.

SAFETY CONSIDERATIONS:

No riders are permitted in the truck during the pull attempt.  Driver may not leave the driver’s seat while vehicle is on the pulling track.  Driver will take all direction from the flagman on the track.

HITCHES:

Trucks that compete regularly are required to have their own hitching device that is subject to approval by the head tech official at each event.  The hitch must work from the 5th wheel with the 5th wheel centered between the two rear axles.  The hitch must be adjustable so the height from the ground to the point of the hook is between 18” and 24” + or – 1”.  The promotor will have hitches at each event.  The hitch will be measure immediately before the semi hooks to the sled.

AIR BAGS:

The use of air bags is permitted.  However, no air may be added to or removed from the air bags while the truck is hooked to weight transfer machine.  Any change in the hitch height by adding air to the bags is cause for disqualification.  Outlaw Pulling Series reserves the right that if suspension lift becomes an issue, we will make all semi-trucks strap both rear drives.

 

WEIGHT OF TRUCK:                                  (22,000lb. MAXIMUM)

The truck shall appear “road ready”.  No added weight or ballast is permitted.  Special trucks, such as oil field trucks that carry additional weight that is not normally found on a “road ready” truck are not permitted in this class.  The promotor reserves the right to weigh a truck at any time.  Trucks with triple (3) rear axles are permitted to pull, but are subject to being handicapped.  The hitch height on a triple axle truck will be set 2” lower than the rest of the class.

SPECIAL RULES:

2.)         Any truck running 2700 RPMs is recommended but not required to have a either a plate over the bell housing of the engine or a certified clutch and flywheel.  

3.)         First puller is the test hook for the class.  If the sled needs to be changed after the first hook, the first puller will be given the option to either drop back into the field at a desired position or pull again.  If the puller decides to pull again, he/she will still have the option of special rule #4.

4.)          If the sled is set properly set, the first puller can either accept his/her first pull or decline the pull and return to a desired position in the lineup.
