Description

The Rust Buster RB4021L is a rear upper trailing arm mount for the driver's side.

Constructed from heavy-duty 8-gauge steel, this bracket is built to OE specifications. It mounts to the front of the rear control arm section inside the frame. The bracket ships with an oil protective coating to prevent oxidation during transit.

Welding is required for installation, and it is recommended to protect the area with rust converter paint.
