'73 and up controls arms - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've noticed alot of people swapping to '73 and up control arms.

Whats the reason for the swap? Better ride? Lowers a bit?

The 73-87 1/2 ton a arms use rubber bushings instead of the 63-72 solid bushings where the control arm shafts atach to the a arms. Some people think they ride better, especially with urethane replacing the rubber ones. I personally prefer older solid ones. You keep them greased and they last prettymuch forever. The newer ones usually have to be replaced every few years as the rubber breaks down.

They're using them mainly because they are more readily available.

The Ball joints are also cheaper so if you switch to disc brakes by using later model control arms and disc it cost's less to rebuild the front suspension.

You can put the newer ball joints in the 67-72 arms. You just have to use a73-87 spindle.

But the 73-87 control arm bolts right to the 67-72 frame and spindle or do you have to use a 73-87 spindle because of the ball joint differences?
