Thanks for all the replies and great info!!
I currently have a TT with GVWR of 6,700lbs. But was towing with my 15’ 1500. Eventually next year going bigger and nicer lol.
i live in the salt belt and I am religious about undercarriage cleaning ever chance I get when the weather warms up.
But….i was able to find out that the part numbers for shocks on the 24’s are indeed the same for the 23’s!!! Took me a ton of research but found GM / AC Delco site to list all shocks used on our trucks for 24 finally. So will be ordering from Rock Auto tomorrow!
