Steeda IRS Subframe bushings improve handling, reduce wheel hop, and improve tire clearance on the 1999-2004 Mustang Cobra. The entire rear suspension of the Cobra is attached to a steel subframe, which in turn is attached to the car with just four rubber bushings. The rubber bushings deflect under load, leading to wheel hop and less predictable handling. Our polyurethane bushing kit substantially reduces unwanted subframe movement and wheel hop. You will notice an immediate improvement in car control after installing these bushings.

Steeda's Subframe bushing kit includes two other important features. First, we include the correct 14mm bolts to fit the car. The forward factory mounting points on the Cobra have 14mm holes but many cars were assembled from the factory with 12mm bolts. We provide new grade 10.9 nuts and bolts of the correct size. This ensures correct alignment of the subframe and prevents the bolts from shifting in the large 14mm holes. Second, Steeda subframe bushing kits include new rear bolts with a low profile round head to increase tire clearance. The low profile allows bigger tires to be installed and the rounded head prevents the tire from being torn by occasional contact with the bolt.

If you have purchased a Steeda Mustang Steel Adjustable Upper Rear Control Arm in the past with us you may be looking to replace the bushing from the kit. This Steeda Mustang Adjustable Upper Rear Control Arm Replacement Bushing Kit is direct bushing replacement for part #555-4100.

Note: Bushings may vary in color, but still function exactly like the original Steeda Bushings that come with 555-4100. Does not fit 1999-2004 Ford Mustang Cobra.
