Prevent damage caused by wheel hopwith Maximum Motorsports differential bushings.

• Urethane bushings prevent rear cover breakage caused by wheel hop.
• Urethane retains low NVH levels acceptable for daily-driven Cobras.
• Includes all 3 bushing sets: The 2 front sets and the critical rear bushing.
• Includes MM-designed tool to easily remove the rear bushing.
• Retains stock differential location and pinion angle.
• Adjusting pinion angle may reduce driveline vibrations. MM aluminum mounts allow adjustment of pinion angle.

Wheel Hop Breaks Parts

• Wheel hop can break the rear differential cover.
• Wheel hop causes violent movement of the differential.
• Violent flopping around of the differential can break the differential cover, where it attaches to the rear mount.
• Violent movement is allowed by the overly compliant stock rubber differential mounting bushings.
• Stiffer bushings, whether urethane or aluminum, prevent the violent flopping around that breaks differential covers.

• Unlike many others who offer only the front differential bushings, Maximum Motorsports took the time and effort to analyze the IRS system. The MM Engineering Team realized that all of the differential bushings must be replaced as a complete set.
• The complete set includes the two front bushings and the essential single rear bushing.
• If only the front bushings are replaced, and the original rubber rear bushing is left in place, a mismatch in the stiffness of the bushing materials will be created. The more rigid front bushings will deflect less, while the remaining rubber rear bushing will still deflect as much as ever.
• Damage from wheel hop will still be possible because the rubber rear bushing will deflect and allow the differential to flop around.
• The mismatch in bushing stiffness will increase the stress on the aluminum front mounting ears of the differential housing. The increased stress can lead to fatigue and stress cracking of the aluminum differential housing.

Steeda Cobra IRS Subframe Bushings 99/01 03/04 - 555-4016

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.

Product Benefits

• Improve vehicle handling
• Reduce wheel hope

Maximum Motorsports IRS Subframe Bushings

Maximum Motorsports introduces a new product for IRS-equipped Mustangs: A Polyurethane IRS Subframe Bushing Kit. The polyurethane bushings in this kit are considerably less compliant than the stock rubber IRS subframe bushings. These stiffer bushings virtually eliminate displacement of the IRS subframe relative to the chassis. This reduces wheel hop during acceleration, braking and cornering. You'll feel a big improvement in your car's stability and predictability. Drivers have reported that the improvement is dramatic, similar to installing a Panhard Bar on a solid axle car. The polyurethane still provides very good noise isolation.

NOTE: It has been found that Ford had put the incorrect bolt in the front mounting holes for retaining the IRS subframe on some 2003 Cobras. The sleeve in the bushing and hole in the chassis are designed for a 14mm diameter bolt, however many cars had 12mm bolts installed incorrectly from the factory. If you have been noticing noise from the rear suspension, it may be caused by the subframe shifting due to insufficent retention with the smaller bolts. Verify the bolt size installed through the front IRS subframe mounts before ordering. If in doubt, or if you determine you need the larger bolts and corresponding nuts, the OEM replacements are available below. You will need two of each to do both sides.Learn More
