I used energy suspension bushings for the upper/lower control arms. Pain to change out but happy with the results.
That's what I used along with liberal amounts of the included silicon lubricant. I think steering response is much better, even compared to new rubber bushings.
Some folks say poly bushings squeak, but I've never had that problem with them in my 82 C10 or my 55 Chevy car. I've also used ProThane poly bushings on other trucks an cars, as well as unknown brands that were included with sway bar kits. Never did hear a squeak from any of them over the years.
Another thing you may hear is that poly bushings make the ride too stiff. Well, we're talking about pickups here, not Cadillacs.
And some of today's rubber bushings will start cracking within a year! Hope that's not the case with GM Professional and Moog parts.
Whatever you do, stay away from the no-name bushings with too-low-to-be-true prices.
