Ridetech 90000894 Tall upper Ball Joint for GM A/F/X Body.

These 1/2 inch Taller Upper Ball Joints fit 1967-1969 GM F Body (Camaro/Firebird), 1964-1972 GM A Body (Chevelle, Cutlass, Skylark etc) and 1968-1974 Nova. They are compatible W/ StrongArms, stock arms, stock spindle (Not for use W/ tall spindles.)

Most OEM front suspension geometry, in addition to being designed over 50 years ago, induced positive camber when cornering (loaded tire leans away from the turn).

This is a huge compromise in cornering performance and feel. By installing a taller set of balljoints, we reposition the control arms to correct this condition and create a much more stable and enjoyable driving and cornering experience.
