Magnum is making a 5" drop "I" beam axle. Shocks mount to axle to keep the spring perch nuts above the scrub line. Looks hood but, compared to a 4" drop unit, you have to come almost twice as high off your billfold.

I like the forged Chassis Engineering 4" drop unit. Worth the small premium over a cast Super Bell or Magnum.

But what do I know??
