I have a 1984 GMC Sierra 1500 Long bed truck. It is a single cab with not many upgrades. I am looking to lift it maybe 4" and i was wondering if i could get some advice oh what would be the best. Right now the truck has 31" tires but i would like to run 35". I am a young teenager with a well paying job so money isn't that big of a deal but i would love to keep the prices low so if i could get some help with this or anything else that i should know about it. Also i am looking to make my truck look very nice and maybe take out the bench and put in 2 seats and a center counsole. I would love to hear thoughts on this idea or if someone has tried this themselves. Thank you so much.
