Explain it to me - top or bottom hole upper shock mounts

[edwardb]

I'm going to use the QA1 shocks mounted inverted to be able to access the adjustments. I just can't figure what difference it would make to use the upper vs lower holes in the upper control arm.

The brand shocks and where you place the adjuster really doesn't matter for your question. I don't know how to explain any differently. I did look back at your picture though and see you have the entire suspension in the upper holes. In that case, following the Factory Five instructions, the shocks should also be in the upper holes. I would only caution you that the entire setup needs to be taken into account, e.g. your desired ride height and the tires/wheels you're using. The hot rod (and truck) has the grille quite low in the front. My truck build (same front suspension as the hot rod) has front ride height at 5-1/2 inches, rear at 6 inches, 18 x 8 wheels and 245/45ZR18 tires all around. I used the lower suspension holes and my grille is no more than 3 inches off the ground.

Ride height is definitely a concern with the low nose on these things. That'll be a game time decision once the wheels and tires and body all go on together to see where she sits. If it's too low, i'll swap everything to the lower holes.
