Question Do I need a telescoping steering shaft for drag car that twist

Do I really need a telescoping steering shaft if my 70 Chevelle twist on launch? is there much movement between the column and steering box

Im changing the shaft out to a smaller style for clearance like the Borgeson Steering Shafts,http://bionicengineering.net/media/IMG_0904.JPG


or pick below

does anybody make a smaller version than the Borgeson one

Thanks
Rob

The car shouldn't be twisting. That should only be suspension movement. The body should move with the frame.

From the launch photo, I'd think a drag specific rear ARB might be helpful.

Re: Do I need a telescoping steering shaft for drag car that twist

when it launch's once its up in the air it looks like the front end/fire wall froward is twisting,

just wondering if its sliding in the stock steering shafts,

or not enough movement to change out to the above w/ no slip joint

Re: Do I need a telescoping steering shaft for drag car that twist

Look at your bumper line compared to the pavement, the right rear tire is buried in the fender well, left tire is almost out. You need an ARB not a steering shaft.

I installed an ARB and dropped 2 tenths on my 60 foot.

Re: Do I need a telescoping steering shaft for drag car that twist

Listen to the ARB recommendations.
I'm glad I did.
My 65' used to twist and list out of the hole like a sailboat on launch, worse than yours does.
After installing the ARB it now launches flat and square like a brick.

Question Re: Do I need a telescoping steering shaft for drag car that twist

Thanks for the advice but It has a ARB.

The Chassis Works arb was sold to me as a ARB,told them what was to the car and a video from the front of the launch. $519 latter, I send them the video view from gopro of rearend and arb twisting, they then said it was a street ARB.


Like Blown1932 I need a (drag specific rear ARB) after headers (steering shaft) I've got TRZ building a 9in w/ a real ARB.

Back to the steering shaft

Thanks
Rob

Re: Do I need a telescoping steering shaft for drag car that twist

If the front end is moving that much there is bigger issues. I was going 9.30's with stock steering parts and no front bracing with 1.28 60' times carrying the wheels every pass.

Re: Do I need a telescoping steering shaft for drag car that twist

Nice looking ARB, but it looks like it is not controlling the body roll, the bar must be flexing, or allowing flex, is what my conclusion would be. My last bolt on ARB was bent 3/4" out of square when I took it off, but was still launching flat, no roll.

Hi , you could move those brackets that hold the arb to the diff housing further apart , out to where the arb just starts to bend and go forward , that will get the most stiffness out of what you got

Here is how the car was with the stock steering, roll cage ended at the dashboard, and stock motor mounts.
