HDK upper control arms with built in caster increase. No more bind.

[HemiDenny]

HDK now offers its latest version chromoly tubular UCA assemblies with built in caster increase for the 73 and up (disc brake conversion) spindle. This same UCA is used with the HDK coil over only conversion.

Install the control arm with the supplied aluminum spacers on each side of the adjustable, street friendly poly ends with the OEM cam alignment adjusters @ 12'clock (middle)....4 degrees positive caster.

keep the OEM cam adjusters @ 12 o'clock (middle) and......

a) stack the spacers on the BACK side of the poly end........2-1/2 degree positive caster

b) stack the spacers on the FRONT side of the poly end.........5-1/2 degrees positive caster

BONUS!!!! thread both adjustable poly end inward / outward equally and achieve extreme camber changes (if desired) WITHOUT putting the UCA in a bind.

Any HDK customer with the older version can exchange for the newer version for only $99 (plus shipping / $20 in lower 48)

available for the early spindle also....just doesn't need the ball joint receiver moved rearward as much because as many know, the early spindle / lower ball joint have the proper (at that time) caster built into them.

later spindle on left...early on right. notice the built in caster angle on the early version. When Chrysler went to the later (off the shelf) bigger spindle, they should have re-designed the control arms to at least have the same caster as the early version.
