CPP tubular control arms
 

anyone know if the CPP tubular control arms re-position the front wheel to center it more in the wheel well like the Porterbuilts? or do they just offer better alignment geometry than stock??

Re: CPP tubular control arms
 

I've never read any info about CPP's arms changing the wheelbase.

Re: CPP tubular control arms
 

It's my understanding that they just provide better alignment geometry. I'm getting ready to install a set (coils not bags) and will let you know.

thanks Hart Rod....was considering the Porterbuilts for improved geometry and centering of the wheel in the wheel well but the CPP are more economical if they do the same thing? havent heard any hype about it on the CPP side so I'm asuming they dont but thought I pop the question anyway and see what shakes out....keep me posted on the arms if you can?

Another benefit of PB's arms are they utilize Delrin type bushings vs poly. Delrin is more precise & less binding.

Re: CPP tubular control arms
 

As far as I am aware, we are the only company building arms that locate the lower ball joint "forward" for improved performance and aestetics. For now anyways. :)

The CPP arms also use a solid style bushing... I don't believe it is delrin, but a similar material. They are a nice product.

Nate - do you have to change upper and lower to do the 1" forward mod? Can you do 63-70 balljoints?

Re: CPP tubular control arms
 

Hotchkis arms also move the wheels forward. Lots more $$$ though.

Re: CPP tubular control arms
 

In order to get the most performance gains (increased castor) you can run the lower arm only. It doesn't move the wheel quite as far forward as doing the upper and lower as a set. We sell quite a few of the lower arms only.

If it is more of the aestetic centering of the wheel that is desired, then the uppers combined with the lowers will give the best result.

63-70 ball joints are no problem. :)

Re: CPP tubular control arms
 

Yes, definitely wanting to center the wheel for improved aesthetics.....some of our trucks seem to be more noticeable than others and likely mine will be noticeable with a 5.5/7 static drop....so if the Porterbuilt upper and lower arms together move the wheel forward in the wheel well effectively 1", how much does just the lower alone move it....is it 1/2", 3/4", 1/4"....any idea?

the PB lowers come complete with year specific (67-70 or 71 & 2) ball joints correct?

what type of sway bar can be used....does it require changing to an end link style?

Re: CPP tubular control arms
 

Typically we move the upper ball joint forward approx. 1/2" and the lower 1" when we do the set. This moves the wheel forward in the 3/4" range... it is very noticeable.

We can also build them where the upper AND lower are moved forward 1". This moves the wheel the whole inch forward. This configuration doesn't get the same castor gain.

If we do the lowers only, it will move the wheel forward right between 1/2" and 3/4".

Here's a pic of the upper and lower forward arm combo (factory x-member with bags)

So the arms on "Picacho" are both moved forward 1"? Uppers 1" and lowers 1"?
