Hello Everyone,

I need to order new trailing arms for my 1963 Grand Prix... Mine are bent I think someone tried to use a jack to lift the rear on both sides and the metal is very thin... Do you guys know anyone that sells aftermarket trailing arms that are stronger?

Regards

I would try Jegs or Summit, but anyone should have em really.  NPD, Ames, OPGI, Ebay.   Tube is strongest of course, but you can get originals and box them.  

Thank you JUSTA6

I only found one company PMT but the set with the hardware and braces are close to $900 + tax + shipping...

Ames, OPGI and ebay do not have it.  I am going to look at NPD now.. 

Wow.... Had no idea it would be that pricey.  

Hi performance tubular control arms or,trailing arms are a tad more expensive than stamped steel OEM/OER replacements. However, the resist deflection more because they are stronger units. 
 

Shop around. The GP is also on a Catalina/Bonneville chassis, I would be surprised if the control-arms or trailing arms for a 63 Chevy didn’t interchange. Chevy prices are often lower. 
 

The cost factor you are dealing with is that this is a full size car and not an A or F body car. Therefore demand for full size performance suspension parts is a lot lower.

from what I can see they are repairable . Save your money 

get them straight and box them with a bit of plate steel 

both my lower trailing arms on my 64 where damaged by a fork lifter I recon .. but I put them in the press and straightened them

Jegs has em, you could contact their tech support.  Showing some as affordable as a couple hundred bucks.  Was going to suggest contacting QA1 directly, but contact Jegs or Summit my original choices.  

No disrespect to QA1 gear, it is top notch, but it also pricey. I often find better pricing with UMI Performance products.

I checked Jegs and Summit they dont have it listed... I am going to try to connect with Jegs tech support.  QA1 only has 69+ pontiacs nothing for the earlier years...

UMI's 64-70 B-body also shows fitment for 59-70 full size Chevy's. Should be the same chassis. You can also call UMI Tech Support too in order to validate fitting your GP.

Thanks Frosty, I did contact UMI and they told me that they do not have anything that fits..

Mine are very soft not sure if there are all like that or it is because they are rusty, the bushings are also very dry rotted and will need to be replaced... I rather replace with a tubular design, I will take a second look at it tomorrow.

i have the umi on my a-body with the roto joints. real happy with them.

Thanks Indymanjoe... but they do not make one for a 1963 Grand Prix

Build you own with Speedway parts.  There is a heim joint company that will build whatever you need, seen on 4 wheeler show on Motortrend. Can't seem to find them, but came across this....

Could it be rodendsupply.com?

I believe you nailed it right on the rod end Tim!!!!

Short of finding a true after market replacement, the suggestion earlier to remove them, straighten them, and then box them up is the correct answer. Boxing kits for stamped steel control arms have been around for awhile. You can also make your own if you have the fabrication skills to cut and weld your own steel.
