After getting off active duty I decided to get a 03 Trailblazer. I'm extremely new when it comes to vehicles but the more I research the more I enjoy it and I'm just trying to do a few things. For the most part you guys seem to know what you're talking about (minus a few) so I was needing to get some insight as to how to make improvements. I took it to an offroad shop that a few people recommended and they ordered a lift kit for me. Also getting new sway links and changing the tires to a 31 with maybe a 17 inch rims. What do yall recommend for internal upgrades and modifications. I'm open to all suggestions. Thanks for the help.
