Increasing front Castor on 65 Beaumont ??????????

427carl · A Poncho Legend!

Why increase the castor? just wondering

Welcome here Peterpeter. I am betting that's formerly Kelico's car?

And what is the difference between the Chevelle shaft and your's? Is it to do with bushing shape? I would have guessed Canadian Chevelles and Beaumonts are the same. It seemed to me the US models had a different bushing.

Caster is now at 0 degree now and I have added power steering to the car, the steering wheel is not re centering it self very well, adding positive castor will improve that, plus it will better deal with the bumps in the road.................so I been told

Yes it is Kelly,s old car.................as far as the shaft have a threaded on end cap with a grease nipple, which looks like needle bearing inside.

And the shaft holes in the control arm appear to be smaller.

SC&C website, SPC Uppers only should fix the caster, If you really want a handling improvement add the Howe "tall" upper and lower ball joints.

Buy the optional pro light adjusters and alignment adjustments are a dream. Call Mark he is VERY knowledgeable.

Stock lowers are fine. You can barely see the tubular uppers with the rubber flaps in place.

Hi Brian...........Yes that's the shaft design I'm looking for. Do you know were I can purchase a pair of these that have 6 1/2 inch center on the holes. These shaft look the same as the ones on the older chevy trucks ???????????......... Because the vehicle has collector plates on it, I can not change the upper control arms to an aftermarket style without losing my collector status. But under the heading of safety my plan is to take another set of shafts and machine a the hole into a slot by cutting back a 1/4 inch max and make spacers to fit front portion of the old hole. This will allow me to move the control arm back without disturbing my chamber and toe and still keeping my factory control arms. .

Thanks Gary about the taller ball joint, that is also in my plans.

Also someone sent me a note or email or something , but I lose it.... I think It was from Brian ....sorry not great with computer's.

why not switch out the A arms for the 66 style and buy the new shafts with the degree you need

If you are talking about the off set shaft for moog, they only give me max 2 degrees of castor and those shaft only rotate you control arm which will affect other setting , I should be around 4 to 5 degrees from what UMI suspension people have to say and the shaft I have know is has grease fitting , plus it's cheaper, I think. Thanks for your input , it would give me another good option.

Yes those are for 63-69 chevy truck. don't know if they are correct or not.

MY 64 Chevelle and Beaumont have them in it also.
In my Chevelle shop manual is says for the other style (bushing) Domestic and US style and in Beaumont manual it dosen't say that
but calls this style Late Type. Weird..

Yes that was me that sent message asking for your phone number.

Still looking for 2 upper control shafts..........................250-558-7963 Peter

I may have some good news for all of you that have the same upper control shaft ( see picture above ) as I do.
I now have found a pair of used upper control arms complete with shafts. We a great deal of discussion with Brian
(above) we think the shafts are designed to have a castor adjustment built
into the shaft. Now having the advantage of the used pair , I was able to see much clearer how they were mount and
how they operated. It appears that the shaft threads from one side to the other , giving you a different's of just over
a half of an inch. Based on what I can see of my vehicle, is when shaft is centered I'm at 0 degrees castor. Factory spec's
says it to be set at 0 degrees. Moving that upper control arm back towards the fire wall 1/4 of an inch will give your
some were between 1 & 2 degrees positive castors which in turn will better return of your steering wheel when coming out
of a turn. And yes the factory spec's say 0 degrees , but all aftermarket suspension system talk about positive castors and
even GM after 1965 started to built cars with positive castor. When looking at the after market suspension system and
how they built in adjustments for all angles , the Canadian engineers were ahead of there time.

Note : we think these shafts were only used in 1964 and 65.

All the above is an opinion and I take no responsibility for any damages this may
cause, I always get an opinion from some in the know about any changes I make that my involve my safety.

The alignment has been completed , by one of these new wheel alignment system. We managed to get 2.4 degrees castor on the right and 2.1 degree castor on the left side , when some is in the driver seat. All other angles are also with in manufactures Min. Max specifications. Drive ability now is good, I have a nice amount of return in my steering wheel. All in all I'm very happy with the ride and steering of the car and I still have all my oem parts.
