Spindels?

B.R.E.Demon said
Are the spindles on our cars forged or cast? I'm asking because my Pro Stock build will need custom lower ball joints to achieve the correct steering geometry. I'm considering removing the cast-in arm on the ball joint and welding a properly spaced steering arm onto the spindle (similar to the Rod Shop car) to reduce bump steer. This car is for track use only—no street driving.

The knuckles are forged. Why do you want to weld the steering arm to the knuckle? You can bolt any manner of steering arm to the knuckle and doing that will be a stronger arrangement than trying weld to the knuckle. At least that way the steering arm is your only concern.

It looks like using a pan with a mid/front sump would allow a rear steer rack after swapping the knuckles around. Then the steering arms could be heated and brought down for less tie rod spacer, less anti-ackermann by placing the rack closer to the spindle, and much quicker steering with near, normal length steering arms

Swapping Mopar knuckles from side to side accomplishes nothing other than moving the brake calipers, it’s done all the time for that purpose and it doesn’t change the geometry at all. Flipping the steering arms is all that’s necessary, but as you’ve already pointed out unless you alter the geometry of them significantly the Ackerman is lousy. Less of a concern for a drag race only ride, but still a concern.
