Lx, nice to see one of my boxes on such a cool rig. Just became an FJC owner and was just looking around at all the posts and noticed you folks talking about my boxes so I thought I'd say hi.

Like some of the others im concerned about that lock nut coming loose. It could be what you think it is but the forces to cause that are pretty extreme. It your unsure about it and want me to look at it just let me know.

Well, well. Welcome aboard. :flipoff2:

In keeping with the thread title, considering I have scotia's ported box en route, already, with intention of hydro assist, aft mounted the axle (can't do high steer due to radius arms), can you offer any insight on:

Suitable mounting for ram, ram stroke, or any viable input for any idiot (me) to consider?

cool, thanks for the offer. i havent had any issues so far after fixing the steering stops and putting the new input shaft/bearing setup in my old box. the play showed up pretty quickly (during one ride) so im guessing it took a good hit or two that day. i figure the 42's put a lot of leverage on the steering system without steering stops to restrict it so ill see how it does now and ill let you know if i have the same problem again.

by the way, i love the hydro assist, one of the best mods ive ever done to my truck.

hmmmm. thats a new one to me. I have not put a ram on one of those.

Just at a first glance i see two possible mounting options. First is attach the base end of the ram to the long side radius arm mount and brace it back to the axle. If that wont work i would build a bracket that bolts into 4 holes on the diff center section and point the moving end down the long side.

Mount ram the way the arrow the pointing. So the piston is pushing towards the driver side knuckle so you don't have to worry about drive shaft clearance.

Bear with my ignorant, redneck a$$ a second.

If an 8" stroke is the requirement, I'm assuming that the ram would only be ~12" long at center, and ~16" fully extended.

Sound right?

The line side radius arm mount on the application differs than OE. It's the equivalent to a caster plate, in form but not function.

What's the preferred method to measure the required ram stroke, or extended/collapsed lengths, to verify enough room to warrant?
 
You need a 10" ram in that location. That is what I am using.

Dammit, never noticed how much I sound like a hick on that video.

More like redneck but, at least, there's some truth in advertising. Bahahaha (Fer' the record, I'm an Okie).

To truncate a long story, have a ported/upgraded box en route, as well new HP/LP lines from the pump to the box. All other components are new.

Once I can figure out what knuckle studs I need, those will be swapped, as well.

From that point, is it only a matter of measuring the lines, stroke, and ordering?

I won't be able to utilize the tabs that most provide on the axle mount, but have to fab on the DS as LT pointed to, literally (thanks, by the way. Pics are worth 10,000 words) to keep the ram remotely close to parallel with the tie rod, which will probably take six months of thinking, three days of "fabbing" and a lifetime of cursing myself for the chitty job.

What are you gonna do with an FJC, by the way?
