Question about control arms - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Conundrum · 12-20-2009, 05:11 PM

I'm going to start on my 79 GMC crew cab dually soon, I pushed my other trucks back, and I am wondering.

Those who have stepped your lower control arms;
How much did you step them?
Did you mod the uppers?
Have any pics?

It will be static dropped til I can get the money to gether to bag it.

I've never stepped a set of lower arms,... but I have seen it over at www.duallyscene.com.

Lots of good dually specific info over there.

Post up some pics of your project when you get time.

I stepped mine 1-1/2", and didn't touch the uppers. Here's the thread:

It's like a drop spindle for drum brakes (it raises the spindle/hub).

That would bring the scrub-line even closer to the road which is already an issue on these trucks when you lower them more than a mild amount.

Ok, good to know.

Thanks SCOTI!
