went 1" longer with mine with works performance custom built shocks... dont bottom out at all now unless i am two up and forget to adjust the shocks to a 2 up setting. cant tell the diff in looks on the rear wheel or fender. very happy and dont know why hd doesnt just do this with the stockers!

 

Hey Holy-Smokes you wanna sell your stock Nightster shocks?

 

sure thing. but after I get them replaced first

 

Hey Holy-Smokes, I've heard of a lot of people that run two up using Road King air shocks say and they love'em. You can adjust easily from one to two riders. Cheap on fleabay. Factory take offs for like 60 bucks, prices vary. LOL. Worth a try for the price.

 

I love the stance of my N.
I think the OEM rear shocks are a little better than a rigid frame.

If riding double and do not care about stance 12.5 inch (or as above 13.5)
If you like the stance try 11.5.

I haven't replaced my OEM shocks yet I would gamble on the 11.5 inexpensive black colored heavy duty Progressive shocks (with their fork springs to hopefully retain some handling balance).

That's my .02

 

Fitted our 330mm/13" Hagons today. It took so little time it was disappointingly easy! I jacked the bike up using a scissor jack partway along the balance pipe between the mufflers (take care with the plastic belt guard). The only comment I can make is that to get the new right shock on I had to install the bottom bolt first, then jack the bike up to get the top bolt in (the muffler got in the way otherwise). The left one went straight on at that jack setting. Setting the bike back down off the jack allowed me to torque all the bolts up.
