IMPORTANT NOTICE
Ball Joint Info:
Before you install this product, please verify which front spindles you have. We have designed the upper a‐
arms to utilize the 73‐87 style spindles. This type of spindle was widely used in disc brake conversions due to
its easy interchangeability and readily available replacement parts (e.g. ball joints, tie rods). If you have
original 71‐72 style disc brake spindles, you can order ball joints from us to convert the Hotchkis upper a‐arms
to work with that spindle. (Part # FA683)
If you have 63‐70 drum brake spindles, you will need to upgrade your spindles and brakes to take advantage
of this a‐arm kit. Please call if you would like to upgrade your spindles and brakes.
