I have a question for anyone who has worked on sprint cars since my mechanical experience has been on stock cars. Was touring the Hall of Fame yesterday and saw Jan Opperman's orange "shitbox" special. I noticed a ratchet on the left side of the car that was within the driver's reach. It was connected by rods and heim joints down to the adjustment bolt on the right front torsion stop. I thought this was pretty neat since he could have adjusted it during caution flags. I also saw another old sprint car that had the same setup. My question is why I don't see modern sprint cars with any kind of adjustment like this? Is this not needed or useful? Is it a winged car vs. non-wing car thing?
I know the drivers can move the wing back with hydraulics. I've also notice what looks hydraulic lines running to shocks too. Are the drivers able to make shock adjustments from their seat? Obviously I wish I had worked on sprint cars rather than stock cars....

I could've swore I saw a sprint car with one of these about 15 years ago. I wonder if they're outlawed now?

Some say the old ratchet weight jacker was created by Bobby Allen? Today's cars do have cockpit adjustable weight jackers also, as well as the shocks and wing. Sound like a lot to keep a guy busy besides driving.

In non wing racing Robert Ballou and Charles Davis Jr currently have a weight jacking system for their respective rides.

Wing cars are not allowed to run any cockpit adjustable shocks or weight jackers just the wing.
Non wing cars are allowed to have such devices, the rod you're seeing is designed to allow the driver to put weight in the right front of the cars usually done as the track slicks off. The reason you don't see that rod any more is because the new weight jackers are hydraulic and run off of the power steering pump,the driver now has a nob in the cockpit that he can turn to adjust the weight of the car. you can put these on any corner of the car.

They were around before Bobby Allen.

In the past, sprint cars often featured adjustable torsion stops that allowed drivers to fine-tune the handling characteristics of the car during caution flags or pit stops. This adjustment could influence the stiffness or compliance of the front suspension, affecting the car's handling and performance. The ratchet mechanism you noticed connected to the adjustment bolt on the right front torsion stop allowed for quick and convenient adjustments.

The cynic in me wonders if maybe the weight jackers and shock adjustments are being done by remote control by someone in the infield. (Insert evil icon here)
