Hey guys!

I'm just building a Big Rock and installed the HR rockers and the HR front/rear steering blocks/axle carriers(?).
Something seems to be off - the steering acts weird & asymmetric, goes through like an 45 degrees angle when I lift the suspension (long springs & cut out skid plates for max. suspension travel).
What way do the steering blocks go; nut (of the steering puhsrod-holder) up or down?
I'm confused, I've seen a both versions on pictures, and the original setup would suggest nut-down, but the offset of the steering knuckle-holder on the HR blocks doesn't correspond to that...maybe some pics can make that more understandable.
Any input would be highly appreciated! After realizing today that I had the whole front A-arms on upside down, i don't want to eliminate the possibility that I might have messed up somewhere else.

Looks fine to me. Maybe try putting the wheels/tires on and see how everything looks.
 
Those might be for the v1 kratons. What’s the part #
These are for current 6s models

these are for legacy 6s models. I’m not familiar with the big rock so I’m not sure what you need

looks good , let the other guy said, put the tires and stuff back on and you should be fine
 
Thanks for your replies - I put the tires on, and it still isn't right.

Thy are part NRO21M01, for Nero Fazon Big Rock.

Maybe I'm supposed to put on spacers on between pivot ball and A-arms? That could stretch things out and align the blocks.
It's just that I haven't seen that anywhere else, and why would my BR require that...hm.

Solved - they go nut-up (I had them upside-down). Bit of a design flaw, but it's working fine now. Can't wait to finish it all up and get this puppy runnin'!

So, opposite of how the stock nuts are. After looking at the pics again, I see what you're saying. Good job! Now finish that thing and have fun.
