When Glen called us, he said he wanted to build his F-250 with his son. He first asked about a 4" kit but, after many conversations, figured his boy just wouldn't let him off the hook without going to a full 6" Rough Country kit (Kit # 593S). He also added a Rough Country dual steering stabilizer (Part # 87491) to help smooth things out. He already had the exhaust stack installed, so lifting the truck and shoving bigger tires with some shiny new wheels underneath completed the picture. Looks great, Glen!
