On the LR, you could certainly make a swingarm work well. But, I would toss the pullbar.

I say unequivocally, YES. I also prefer the long pullbar, but I never saw Moyer or Babb with anything but the short one. Rayburn Swing arm was still finishing in the top 10 at the world as late as 2009. I think too much is made of where we are now versus 8-10 years ago. Sure the cars(4 link) drive better now, but track records should be falling every week by the way these cars are touted versus the older stuff, but I would say the rate of progress in overall speed is stagnant for the most part. They've gotten more consistent, but not much quicker in my view. I've yet to see a 4-link dig as hard off the corner as a Rayburn Swing arm can. JMO

Don't hammer down, short tracks work better for a swing arm/pull-bar deal? That seems to be their sweet spot IIRC... there seems to be more competitive Rayburn's on some of those shorter tracks in the south than we see here in Cheeseland....

It isn't the lap times in time trials and heat races that has changed. It's the lap times in the slick features that has gotten faster with the more recent technology.

i believe that they can still be competitive,the problem was they would just flat dump when you let off the gas,i would think with todays shocks along with stiffening the chassis like they are doing today(cj's cars would flex alot) they would be very competitive, look at what rumbly was doing, trying to control the rear steer, most 4 bars have too much rear steer come feature time, as far as the pull bar, show me something that creates more forward drive than that, now controlling that, theres the key,

I would love to work with an actual driver and CJ with a swingarm car. I believe they can still get it done!

[HEAVY DUTY]

CJs new swingarm stuff is pretty good. They are quite a bit different than the older stuff. He just needs a few good drivers on it to show how they work. There have been a few who drove his personal car testing that had nothing but good to say about it. I put it on a mod late in the year with CJs help, and won 3 of 6, and broke leading one of them. Should have been 4 for 6. As far as I know, there are only a handful of them out right now. If I had an older Rayburn, I would be calling him up and getting it changed over to the new stuff.

I don't know if I would call that a pullbar or a lift arm.
Always see interesting things here.

Pull bars and Lifts are kinda the same thing anyway. One pulls up the chassis with axle rotation and tbe other pushes up the chassis on axle rotation so they are kids doing the same things with the differences in how to adjust them and packaging.

There is a big difference in the anti squat application point and the transition from lifting to neutral is also very different.

Anyone have pics of this new Rayburn technology?

I get that. I was just trying to point out they have the same job to do.

Riddle this for discussion purposes. If you were remove the Sixth Coil on a Lift arm, remove the spring from a pull bar, mount them to the car in the same place, (basically remove the adjustable part of both) would they not act the same? Would the measured amount of anti-squat come out the same?

No. The long pullbar we ran looked like a regular pullbar only it had a extension. Was mounted on left side of bell and ran down between driveshaft and c@ckpit to the forward driveshaft loop and had 2 mounting holes. just looked like a long pullbar as opposed to his standard one. Just a singular long straight device. We also preferred the short 14-3/8 swing arms.
