forged or stamped control arms

[Schurkey]

I have been trying to figure out what type my LCAs are on my 95 8 lug K2500. Do these pictures look like the second option you described as, "A newer version of the stamped arm apparently uses a permanently-attached (welded?) forged end with a press-in ball joint. I've never seen one of these in person."

Yup. That's them.

I've still never seen a set of those in person.

Thank you for confirming. It's quite an odd design. It seems like it would be weaker than fully stamped or fully forged. I wonder if this style is common on the 8 lug 3/4 tons?

The combo LC's come on K1500 suburban's also

I have the same on my 99 K1500 Suburban. Anyone know the correct ball joint size? Understand choices are 45.79, 46.13 or 47.89mm for pressed.

You need GM part number 12383410 or equivalent. My K1500 Silverado has the same style LCAs.

Reviving this old old thread..

I got a 99 suburban k1500 5.7.

I’m in the middle of purchasing front end components from Rock Auto

I'd like to upgrade my LCA to the forged from the K2500.

What model truck is compatible?

Making my way to the treasure yard tomorrow afternoon

Thanks

Any 4x4 8-lug GMT-400 with forged lower arms. They started later in the 400 run, but both forged and stamped were used right to the end.
