What is a RSK?

I've seen people mention rsk on here. What is it, what does it do, and what does it stand for?

Reverse Shackle Kit.

On the OBS, Ford got REALLY stupid and put the shackle in FRONT of the spring.
the CORRECT location is BEHIND the spring.

a RSK moves the shackle to behind the spring. It corrects the ride and give a lil lift in the process

it is a "shackle reversal" everywhere else but in powerstroke land they call it an RSK.
dunno why but I assume someone's marketing ploy

there are reasons to locate the shackle in the front. with the factory, flat or neg arc, springs the front makes a lot of sense.

I developed the RS-SD mod using SD springs and a RS kit 12-13 years ago, but it Requires a D60 swap. We have helped thousands perform this mod. It will transform a OBS trucks ride. Actually can ride better than any stock SD



We also developed the 99-10 axle swaps with suspension for the OBS.

PM me if I can help.

Then why do the SD(with flat springs) have the shackle in the rear?
