What problem do these UMI Performance spacers solve?

These spacers address the mismatch between the 16mm hole in the Mustang's chassis upper control arm mount and the 14mm bolt used. This difference creates slop, leading to clunks and noise during acceleration and braking.

Will these spacers fit my aftermarket upper control arms?

Yes, these spacers will fit aftermarket upper control arm mounts that utilize a 16mm hole in the chassis. However, most aftermarket control arm manufacturers design their mounts with 14mm holes, so check your specific part.

What material are these spacers made from?

The manufacturer description does not specify the material of the spacers. They are designed to reduce chassis mount hole size and eliminate clunks.

Product Details

This kit from UMI Performance includes stepped spacers designed to fix a common issue on the 2005-2010 Ford Mustang. The factory rear upper control arm mount on these Mustangs has a 16mm hole in the chassis, but the bolt used is only 14mm. This difference creates slop, which can lead to noticeable noise and clunking sounds, especially during acceleration and braking.

These stepped spacers are made to slide into the existing chassis mount, effectively reducing the hole size from 16mm down to 14mm. This tighter fit prevents the bolt from shifting around, which helps to eliminate those unwanted noises and provides a more solid feel from the rear suspension. This kit is designed to work with the original equipment upper control arm mount, and will also fit aftermarket mounts that use a 16mm hole, though most aftermarket arms are designed with 14mm holes.
