Factory Basics

  • Scout 80/800 frames have an inside to inside measurement of 29"
  • Scout 80/800 springs are 1-3/4" wide
  • Scout 80/800 front springs are typically __" eye to eye on center
  • Scout 80/800 rear springs are typically __" eye to eye on center
  • Scout II frames have an inside to inside measurement of 27"
  • Scout II springs are 2" wide
  • Scout II front springs are typically __" eye to eye on center
  • Scout II rear springs are typically __" eye to eye on center

 

Lifting Methods

  • Spring Lift - This involves new springs that have more arc to them which raises the body/frame higher above the axle. This typically results in a rougher/stiffer ride quality.  The frame and axles will now have a greater distance between them, the parts that go between those two will need attention, such as; brake soft lines, steering components and possibly driveshafts. 
  • Spring Over Axle Conversion - From the factory Scouts have the springs mounted under the axles. With custom fabrication the springs can be mounted on the topside of the axles. This will net you a lift equal to the thickness of the leaf spring pack plus the diameter of the axle tube and spring perch. This is usually around 6" of lift. This type of lift also changes the distance between the body/frame to the axle.  Meaning you will need to address brake soft lines, steering components and possibly extended driveshafts.  This lift allows the retention of stock rate springs, which means a softer ride than lift springs, but does require a lot of fabrication for the average owner. 
  • Shackles -  A simple way to get small amounts of lift. For those who don't know, shackles hold the dynamic end of the leaf spring and allow them to compress and extend.  Stock shackles are 3" bolt to bolt. In a basic sense, every inch increase of shackle results in 1/2" of lift. We do not recommend using shackles longer that 5" bolt to bolt. Too long of shackle can create instability and can become very unsafe. 
  • Body Lift - These are spacers that mount on the bushings between the frame and the body.  This is also a simple lift but effects all the parts that crossover between the body and frame. This may include; steering shaft, brake hard lines, brake soft lines (80/800), fuel lines, wiring and radiator/fan shroud mounting.  We do not recommend using body spaces longer than 1" in height. 

 

Other Modifications

  • Reverse Shackle - Meant to improve the travel of the axle when you hit bumps. Requires a fair amount of fabrication and new front driveshaft. 

  • Axle Swaps - Bigger and beefier because of either; more power or more resistance (larger tires). Those Dana 27 axles just wont hold up to running 40" tires. Could be a direct bolt on but typically requires at least some modification. 

  • Spring Swaps - Both longer or wider springs can give you a difference ride quality. Requires a fair amount of custom fabrication.
