Has anyone tried running the pull bar spring setup and removed the 90/10 shock? I have heard you need to run a stiffer spring to make this happen. I just wanted to know what it feels like and how the car reacted. I run a 3 link car with the lr swing arm and eliminator, rr with spring on top of rearend.

Any thoughts?

been running that way for 2 years works great.....it might cause some cars to be loose "in" depending on your set up.

We found the rubber bushings to help with forward bite also. We did find that we had to go to an oil instead of a gas shock on the top of the rear end housing. The gas was robbing forward bite from the car.

Until this year we ran without a 90-10 on a 4-z, but we did have problems with chassis mount being ripped out on pull bar. This year different driver and the pullbar bent a couple of times, put the 90-10 on, no further problems with that or chassis mount. We use quickcar biscuit pull bar. I know of several drivers that don't use a 90-10, works fine for them.

Thank you guys on your responses. What pinion angle do you try to run at with this setup? I use 7 degrees.

Do you run on clay with little sand, or what type of track do you run on? I run in the Kansas City area where we have good clay and the tracks get very dry slick in the summer. Did you go to a 1050 spring on the pullbar?
