What's in the Box

(2) IRS Subframe Supports

Steeda Performance
Bolt on better handling, reduced wheel hop and quality with Steeda's 2015-2026 Mustang IRS subframe support brace kit! This kit is not permanent and will stiffen up the subframe of your IRS for better handling and a more stable ride in the corners. By limiting the movement of the IRS subframe with connection points at the front as well as the lower control arm and toe link, this reduces wheel hop along with the added strength.

Steeda Quality
This kit is constructed of high quality 4130 chrome moly steel for strength and durability. This high quality steel is the powder coated in a silver metal flake that will look great under your Mustang. These quality materials have a lifetime warranty for peace of mind.
