What to expect? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm thinking of buying a set of upper and lower control arms for the truck. I also plan to install the helper air bags I have for the coils also at the same time.

My question: what should I expect out of this swap in performance and ride wise. More the ride than performance since it's a street truck. These are Porterbuilt tublar control arms for a static drop.

With the low cost of quality springs these days, I would suggest to just replace them instead of the helper bags.

Coil overs only way to go. I just got mine back from installing a complete ride tech level 2 system. All tubular trailing and control arms, front and rear sway bars and it rides and handles better than I I was expecting.

I don't know exactly what the drop is but it had a 5/7 before and the front sets a little lower now.

I have the air helpers so I'm going with them + I have them out back also already. Later I will add complete air bags at some point in time. I have the front sway bar already to.

I'm just wondering what will the tublar a arms do for me as in ride and performance.

Another question, the guy I'm getting them from says they have the 73-87 up ball joints. Will these work in my stock spindles?

Just swapping the control arms will not ad to the ride or performance of the truck unless they allow for better alignment specs on the front suspension. Springs and shocks will do much more for the performance and ride than anything else. As far as the ball joints go if you are running they wont match the 71 spindles.

So I will need the ball joints for the 71 then. I rebuilt the a-arms when I bought the truck 28 years ago maybe a year are two afterwards so putting new bushings and stuff will help it out also I'm sure.
