Hotchkis 11390U Tubular Upper Control Arms, 67-72 C-10 - Manual

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). The Hotchkis
lower a‐arm ball joints will work with spindles from 71‐87. However, if you have original 71‐72 style disc brake
spindles and you would like to install Hotchkis upper a‐arms, you will need to 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.
Steering Stop Info:
In the following diagrams we will display 3 popular styles of spindles that your truck may be equipped with.
Due to the variants in spindles that are available, you may need to modify the steering stop on your spindle to
allow for proper steering angle. (Approx. 30°) Please see below.
