Ya, no problem realter. Just being a smart aAs.
Lower Stableloads are more versatile and help more with sway at a higher ride ht where Timbrens to get the same ride ht may not let the lower leaf spring engage. They'll hold the load up but sway a bit more.
Plus you can disengage the stable loads when not hauling a load.
Only downside is drilling the spring, but I think? Your Chevy has a hole in each spring end already. Which makes them a super simple install.
If you have basic tools and a jack you can install either without much issue if the shops are charging more than you wanna pay.
On a 1-10 scale of complexity and tools required for mechanic work, both of these things are about a 2 to install.
