Ball Joint Reinforcing Ring
This ring is used to help secure the upper ball joint to the upper control arm. The control arm is sandwiched between the ball joint and the reinforcing ring.
Similar to AMG P/N 12460150B3 (no longer available) originally about $25 each.
Made from 1/4" thick steel with black anti-corrosion finish.
Note: Some later-year trucks already have this piece, usually welded to the control arm. On these trucks, this ring is of no additional benefit. Contact us if you have questions.
