Hey, you guys im new to this thread I have been a member over at fscf for a while. I came across this forum doing a search for cognito lifts and found that sweet white gmc whoever owns that your truck is bad ass. Well anyway I was looking for a lil help here. I have a 00 silverado with a 4 inch rancho lift and a three inch body lift. That I wheeled way to hard the truck is sitting on three wheels right now. I busted the front right wheel completely off the truck when I was mudding and hit a huge tree stump down here in florida. Well I decided I want to go bigger and this gives me a reason to. Well my question is should I go with a cognito lift for the money or should I go with the sfa even though I would only be able to afford a dana 44 and keep my stock 10 bolt rearend with 456 gears. Or should I opt for the cognito lift kit and save a lil money possibly. Would this ifs kit handle a set of 39.5 inch tires. Thinking that if I get the cognito I might not offroad nearly as much. Any suggestions would be appreciated. Thanks in advance.
