USD Forks

You will probably need longer pre-load tubes (Zed1015 will be the man to answer this as it was his mod)

I think I’m doing your mod Wookie, where you just add the couplers to the top just under the fork cap. Doing it at the bottom like Zed did is slick, but more complicated than I think I’m set up for. 

With the damper rod extensions you can gain 32mm in length.
This does not affect pre load or spring tension in any way and no other mods are needed.
All they do is allow the stanction and attached axle clamp to protrude 32mm further out of the sliders.
You may wish to add an additional 32mm of fork oil to each leg but i have found no noticable difference using the stock amount.

Thanks Zed, I'm picking up what you're putting down. For my needs I won't need to go the full 32mm allowable, I think I only need about 20mm, but I will double check my math before I make any spacers. The complicated bit is just fork disassembly/reassembly in the first place.
