Notice the blue ring on the 10" King. It's sitting about . 25" below the top the bump stop. The bottom heim joint on the King is 2" long.
2" hiem + . 25" below the top of the bump stop = 2. 25" of bump stop being used before it even hits the axel. The stock bump stop is 2. 5" long, leaving . 25" of usable factory bump stop before the shock is collapsed metal to metal.
This is using my shock tower that is taller than what's on the market.
