Shackles

[SLO_F-250]

Hey guys. Getting ready to slap together a leveling kit for my truck. Ive read on here that an extended shackle alone will do the trick. My stock tires are about done and Im going with 285/75 R16's.

The stock Shackle is 5" eye to eye, and I read on here somewhere that the leveling shackle is 8" eye to eye. Has anyone had any problems with running this setup, and do you really need a longer track bar for raising the front 1-3/4ish inches?

Thanks for the input!

An 8" eye to eye rear shackle will lift the truck 1.5". Most consider a leveling kit to be a 2.5" front lift. The problem with only adding a rear shackle is that it pivots your pinion down. With a small lift such as you are trying to accomplish it isnt too big of a deal but it will add more driveline angle which could cause vibrations in offroad conditions and will wear components faster. A longer track bar is not needed for a leveling kit, also just a heads up if you decide to add an adjustable track bar or such later, the early 99's use a small diameter bolt than the later models do.

Not the way to raise a truck, will change the Castor.You need to get a true hanger kit. You need a adj track bar or a drop bracket made correctly for your lift Every 2" of lift WILL shift the axle 1/2-3/4" its Geometry.

x2... buy a kit that has shackles AND hangers, or even better new springs.
