Heavy duty upper clamps improve durability in hard crashes and accommodate the inner shock mounting system.

The upper clamps use caster inserts for quick and easy set-up changes, and feature centering pins for precise installation and improved crash reliability.

The screws installed from the bottom of the caster inserts capture the inserts in the upper clamps to secure the inserts while servicing the car. The screws also serve as the upper arms pivot ball mounts, reducing the number of components in the assembly and reducing weight.

The upper clamps and caster inserts are made from premium Swiss 7075 T6 aluminum and black anodized.
