Replacing the upper and lower control arm bushing on my 2003 Silverado 1500 2WD 5.3 this weekend. Looking for the lower spring insulators, but none of the auto parts stores (nor Rock Auto/Summit) have the replacement. That being said, I did order a few options from Amazon (Energy Suspension) that may fit what I need. If they don't fit, can I just run the spring directly in the control arm....kinda what is happening now with the old parts worn and almost non existent

 

Welcome from Florida. Did you try the dealer? I would rather pay the dealer extra than use worn out parts. You may also be able to slightly modify bushings from other vehicles that are similar to yours. i can get bushings for 1949 Chevy so you should be able to find something for your 2003.
