Looking to upgrade my shocks from AC Delco with about 25,000 miles on them. they will go on a 2008 Chevy LMM with 224,000 miles on it. I purchased it with 199,000 miles on it 5 years ago. I use the truck mainly for towing my 34 foot travel trailer and a few Baja fishing trips a year. Baja is where I really feel is where all the punishment comes from. any suggestions would be appreciated.
