I have a 2014 SR5 4wd with 136000 miles and have been considering replacing shocks, springs all around based on the age and milage. It has a little rock, but not bad and not an emergency. I see 4r suspension sets on fb market regularly from people who have lifted/changed. For example one person is selling their old stuff for $150 and only has 12k miles on it. You can't get a front strut for $150 for one side at the dealer. Any reason I shouldn't do something like this?
