you make some valid points here doug, however, i will have to disagree with you for once. i did the shackle flip in my RC and use/will use it as a daily driver. while it does cahnge the way the vehicle handles, it is not so extreme that it does not function well or that he can not get used to in a short period of time. i will admit that you cannot corner the truck like mario andretti on crank, but it does handle extremely well.chrysler300le said:This could start an arguement or debate but I wouldn't use a shackle flip on a daily driver. Seeing that your 15 yo i'm sure this would be your first set of wheels and probably the only thing you have to drive. If this is going to be a daily driver and more for looks go with a true lift kit with springs. Leaf springs are designed with the front half doing most of the work and load bearing while the rear half is more for comfort and suspension travel part of the deal. The rear spring eye is higher then the front eye. With the shackle flip the rear eye becomes lower then the front eye and makes the rear half of the spring do more of the load bearing. The rear half is more flexable then the front half so the ride is smoother and suspension travel is increased. The trade off is that stability and load bearing is decreased. It could cause some funky handeling. Some might argue that its tolerable, but they probably don't push a vehicle in the corners like I do or like a 16 yo might. You can't have the best of both worlds, need to decide if this is a true trail truck or a work or for looks truck.
