I would say it's hard to tell with the wheel on. if the wheel is off you could see where the spline is on the spindle, if it is low on the spindle (below the halfway point) then it would be stock. if the spline is higher on the spindle (close to halfway or higher)then it would be a lowered spindle.
I'm no expert with this stuff but that's how I see it when you look at spindle pictures online.
Thanx, yeah i figured on that approach but i've no idea where the shaft would be on the stock spindles, the shaft is quite close to the bottom b/j so i'm guessing they're stock and i just have lowered springs.
